Secondary Intraventricular Hemorrhage Research Articles

Neutrophil extracellular trap-mediated impairment of meningeal lymphatic drainage exacerbates secondary hydrocephalus after intraventricular hemorrhage.

Rationale: Hydrocephalus is a substantial complication after intracerebral hemorrhage (ICH) or intraventricular hemorrhage (IVH) that leads to impaired cerebrospinal fluid (CSF) circulation. Recently, brain meningeal lymphatic vessels (mLVs) were shown to serve as critical drainage pathways for CSF. Our previous studies indicated that the degradation of neutrophil extracellular traps (NETs) after ICH/IVH alleviates hydrocephalus. However, the mechanisms by which NET degradation exerts beneficial effects in hydrocephalus remain unclear. Methods: A mouse model of hydrocephalus following IVH was established by infusing autologous blood into both wildtype and Cx3cr1-/- mice. By studying the features and processes of the model, we investigated the contribution of mLVs and NETs to the development and progression of hydrocephalus following secondary IVH. Results: This study observed the widespread presence of neutrophils, fibrin and NETs in mLVs following IVH, and the degradation of NETs alleviated hydrocephalus and brain injury. Importantly, the degradation of NETs improved CSF drainage by enhancing the recovery of lymphatic endothelial cells (LECs). Furthermore, our study showed that NETs activated the membrane protein CX3CR1 on LECs after IVH. In contrast, the repair of mLVs was promoted and the effects of hydrocephalus were ameliorated after CX3CR1 knockdown and in Cx3cr1-/- mice. Conclusion: Our findings indicated that mLVs participate in the development of brain injury and secondary hydrocephalus after IVH and that NETs contribute to acute LEC injury and lymphatic thrombosis. CX3CR1 is a key molecule in NET-induced LEC damage and meningeal lymphatic thrombosis, which leads to mLV dysfunction and exacerbates hydrocephalus and brain injury. NETs may be a critical target for preventing the obstruction of meningeal lymphatic drainage after IVH.

Analysis of the diagnostic informativity of non-contrast computed tomography markers of intracerebral hemorrhage expansion in assessment of the individual risk of early neurological deterioration in patients with hemorrhagic hemispheric stroke

The aim of the study was to evaluate the diagnostic informativity of non-contrast computed tomography (NCCT) markers of intracerebral hemorrhage (ICH) expansion in assessment of the individual risk of early neurological deterioration (END) in patients with hemorrhagic hemispheric stroke (HHS). Materials and methods. A prospective, cohort study was conducted involving 333 patients in the acute period of hypertensive spontaneous supratentorial ICH on the background of conservative therapy. The level of neurological deficit was assessed using the Full Outline of Unresponsiveness (FOUR) coma scale and the National Institute of Health Stroke Scale (NIHSS). The computed tomography of the brain was used to verify the ICH volume, the midline shift (MS), the secondary intraventricular hemorrhage volume (IVHV) and NCCT markers of intracerebral hemorrhage expansion. As a combined clinical endpoint, END was considered (decrease of the FOUR scale score ≥2 or/and increase of the NIHSS score ≥4 or/and lethal outcome within 48 hours of hospitalization). Results. Early neurological deterioration was registered in 112 patients. On the basis of a comparative analysis, it was established that the specific weight of END was significantly higher in subcohorts of patients with individual NCCT markers of intracerebral hemorrhage expansion, than it was in subcohorts of patients without corresponding NCCT signs (p ˂ 0.0001). It was established that the following NCCT markers of ICH expansion are the most sensitive predictors of END: hypodensity, swirl sign and irregular shape (sensitivity >90.0 %). The most specific NCCT markers were island sign, black hole sign, blend sign, satellite sign and heterogeneous density (specificity >87.0 %). In accordance with the multiple logistic regression analysis, hypodensity (OR (95 % CI) = 13.56 (4.54–40.49), p < 0.0001) and island sign (OR (95 % CI) = 5.94 (2.05–17.16), p = 0.0010) are independently associated with the risk of END. A highly sensitive multi-prediction logistic regression model was elaborated in order to predict END in patients with HHS which takes into account the most informative NCCT markers of ICH expansion (hypodensity, island sign) and quantitative neuroimaging indicators (MS, IVHV) (AUC ± SE (95 % CI) = 0.92 ± 0.02 (0.89–0.95), р ˂ 0.0001). Conclusions. Non-contrast computed tomography markers of ICH expansion are associated with increased risk of END in patients with HHS. Hypodensity and island sign are independent predictors of END. The integration of NCCT markers of ICH expansion with quantitative neuroimaging indicators (MS, IVHV) in the structure of the multi-prediction logistic regression model allows to assess the individual risk of END with an accuracy of >85.0 %.

Intraventricular Lavage vs External Ventricular Drainage for Intraventricular Hemorrhage

Intraventricular lavage has been proposed as a minimally invasive method to evacuate intraventricular hemorrhage. There is little evidence to support its use. To evaluate the safety and potential efficacy of intraventricular lavage treatment of intraventricular hemorrhage. This single-blinded, controlled, investigator-initiated 1:1 randomized clinical trial was conducted at Aarhus University Hospital and Odense University Hospital in Denmark from January 13, 2022, to November 24, 2022. Follow-up duration was 90 days. The trial was set to include 58 patients with intraventricular hemorrhage. Prespecified interim analysis was performed for the first 20 participants. Data were analyzed from February to April 2023. Participants were randomized to receive either intraventricular lavage or standard drainage. The main outcome was risk of catheter occlusions. Additional safety outcomes were catheter-related infections and procedure time, length of stay at the intensive care unit, duration of treatment, and 30-day mortality. The main outcome of the prespecified interim analysis was risk of severe adverse events. Efficacy outcomes were hematoma clearance, functional outcome, overall survival, and shunt dependency. A total of 21 participants (median [IQR] age, 67 [59-82] years; 14 [66%] male) were enrolled, with 11 participants randomized to intraventricular lavage and 10 participants randomized to standard drainage; 20 participants (95%) had secondary intraventricular hemorrhage. The median (IQR) Graeb score was 9 (5-11), and the median (IQR) Glasgow Coma Scale score was 6.5 (4-8). The study was terminated early due to a significantly increased risk of severe adverse events associated with intraventricular lavage at interim analysis (risk difference for control vs intervention, 0.43; 95% CI, 0.06-0.81; P = .04; incidence rate ratio for control vs intervention, 6.0; 95% CI, 1.38-26.1; P = .01). The rate of catheter occlusion was higher for intraventricular lavage compared with drainage (6 of 16 patients [38%] vs 2 of 13 patients [7%]; hazard ratio, 4.4 [95% CI, 0.6-31.2]; P = .14), which met the prespecified α = .20 level. Median (IQR) procedure time for catheter placement was 53.5 (33-75) minutes for intraventricular lavage vs 12 (4-20) minutes for control (P < .001). This randomized clinical trial of intraventricular lavage vs standard drainage found that intraventricular lavage was encumbered with a significantly increased number of severe adverse events. Caution is recommended when using the device to ensure patient safety. ClinicalTrials.gov Identifier: NCT05204849.

Natural History, Pathophysiology, and Recent Management Modalities of Intraventricular Hemorrhage.

Intraventricular hemorrhage (IVH) is a clinical challenge observed among 40-45% of intracerebral hemorrhage (ICH) cases. IVH can be classified according to the source of the hemorrhage into primary and secondary IVH. Primary intraventricular hemorrhage (PIVH), unlike secondary IVH, involves only the ventricles with no hemorrhagic parenchymal source. Several risk factors of PIVH were reported which include hypertension, smoking, age, and excessive alcohol consumption. IVH is associated with high mortality and morbidity and several prognostic factors were identified such as IVH volume, number of ventricles with blood, involvement of fourth ventricle, baseline Glasgow Coma Scale score, and hydrocephalus. Prompt management of patients with IVH is required to stabilize the clinical status of patients upon admission. Nevertheless, further advanced management is crucial to reduce the morbidity and mortality associated with intraventricular bleeding. Recent treatments showed promising outcomes in the management of IVH patients such as intraventricular anti-inflammatory drugs, lumbar drainage, and endoscopic evacuation of IVH, however, their safety and efficacy are still in question. This literature review presents the epidemiology, physiopathology, risk factors, and outcomes of IVH in adults with an emphasis on recent treatment options.

Prediction of Permanent Shunt Dependency in Patients with Intraventricular Hemorrhage: Outcomes of Early External Ventricular Drainage Weaning Protocol

Hydrocephalus remains a common sequela of intraventricular hemorrhage (IVH) despite adequate drainage of the hematoma, including endoscopic surgery, intraventricular fibrinolysis, and external ventricular drainage (EVD). Moreover, the appropriate timing for conversion from EVD to ventriculoperitoneal shunt (VPS) is uncertain. This study aimed to evaluate the predictors of shunt dependency in patients with IVH based on the early EVD weaning protocol in our institution. We retrospectively reviewed medical records of patients who were diagnosed with primary IVH and secondary IVH from spontaneous intracerebral hemorrhage during the period 2018-2021. Predictors associated with shunt dependency were identified using a logistic regression model. The cutoff point of each variable was selected by receiver operating characteristic curve analysis. Furthermore, shunt complications were reported as a safety measure of our early EVD weaning protocol. The analysis included 106 patients. After IVH treatment, 15 (14%) patients required ventriculoperitoneal shunt, whereas 91 (86%) patients were shunt-free. The diameter of posttreatment temporal horn and the degree of IVH reduction were the significant predictors of shunt dependency. Moreover, patients with IVH reduction of >45% and temporal horn diameter of <9 mm had a lower probability of shunt dependency. Shunt failure was found in 2 (13.3%) patients. This study showed that a large temporal horn diameter and a lower degree of IVH removal were predictors of shunt dependency in patients with IVH. In addition, early conversion from EVD to ventriculoperitoneal shunt is safe and feasible.

A deep learning model for automatic segmentation of intraparenchymal and intraventricular hemorrhage for catheter puncture path planning.

Intracerebral hemorrhage is the subtype of stroke with the highest mortality rate, especially when it also causes secondary intraventricular hemorrhage. The optimal surgical option for intracerebral hemorrhage remains one of the most controversial areas of neurosurgery. We aim to develop a deep learning model for the automatic segmentation of intraparenchymal and intraventricular hemorrhage for clinical catheter puncture path planning. First, we develop a 3D U-Net embedded with a multi-scale boundary aware module and a consistency loss for segmenting two types of hematoma in computed tomography images. The multi-scale boundary aware module can improve the model's ability to understand the two types of hematoma boundaries. The consistency loss can reduce the probability of classifying a pixel into two categories at the same time. Since different hematoma volumes and locations have different treatments. We also measure hematoma volume, estimate centroid deviation, and compare with clinical methods. Finally, we plan the puncture path and conduct clinical validation. We collected a total of 351 cases, and the test set contained 103 cases. For intraparenchymal hematomas, the accuracy can reach 96 % when the proposed method is applied for path planning. For intraventricular hematomas, the proposed model's segmentation efficiency and centroid prediction are superior to other comparable models. Experimental results and clinical practice show that the proposed model has potential for clinical application. In addition, our proposed method has no complicated modules and improves efficiency, with generalization ability.

Outcomes of Combined Endoscopic Surgery and Fibrinolytic Treatment Protocol for Intraventricular Hemorrhage: A Randomized Controlled Trial.

Intraventricular fibrinolysis (IVF) and endoscopic surgery (ES) are the new promising treatment strategies to enhance the rate of hematoma clearance, which might improve functional outcome. This study investigated and compared the outcomes among these interventions. A randomized (1:1) double-blinded trial was carried out between August 2018 and December 2021. The intervention and control groups comprised patients receiving IVF and/or ES and external ventricular drainage (EVD), respectively. All participants had experienced primary or secondary intraventricular hemorrhage (IVH) from spontaneous intracerebral hemorrhage with obstructive hydrocephalus complications. The primary outcome was modified Rankin Scale score 180 days post treatment. Interim assessments were planned for every 50 participants enrolled to ensure safety and efficacy. After enrollment of 110 participants (55 participants in each group), there was a difference in 30-day mortality (2 [3.6%] vs. 13 [32.7%] in the EVD group, P= 0.002), reaching the predetermined boundaries for termination of the trial. We demonstrated a better favorable outcome (modified Rankin Scale score 0-3) at 180 days in the intervention group, compared with the control group (35 [63.6%] vs. 24 [43.6%], P= 0.04). Participants in the intervention group experienced a higher IVH removal rate (91% [9.0] vs. 69.5% [38.0], P < 0.01) and had lower shunt conversion (1 [1.8%] vs. 16 [29.3%], P < 0.01). Treatment complications were comparable between the two groups. This study demonstrated that combined ES and IVF is safe and effective for the treatment of IVH. In addition, it concluded that aggressive but safe procedures used to remove IVH could improve clinical outcome in patients with IVH.

Study protocol for ACTIVE study: safety and feasibility evaluation of external ventricular drainage with ACTIVE fluid exchange in intraventricular hemorrhage—a phase 2, multi-center, randomized controlled trial

BackgroundPrimary intraventricular hemorrhage (IVH) or IVH secondary to intracerebral (ICH) and subarachnoid hemorrhage (SAH) are known to have a very poor prognosis, with an expected mortality between 50 and 80% (Hinson et al. Current Neurology and Neuroscience Reports 10:73–82, 2010). Clearance of IVH might improve patient outcome.MethodsThe study is designed as an investigator-initiated, comparative, prospective, multi-center, 1:1 randomized phase 2 trial evaluating the efficacy and safety of active irrigation in external ventricular drainage (intervention arm—IRRAflow) compared to passive external ventricular drainage (control arm—EVD).The trial will enroll 58 patients with primary or secondary IVH. Major eligibility criteria include age ≥18 years of age, IVH documented on head CT or MRI scan (Graeb score ≥3), need of cerebrospinal fluid drainage, deterioration of consciousness or medical sedation at the time of enrollment, and indication for active treatment evaluated by the treating physicians. Exclusion criteria included patients with fixed and dilated pupils and pregnant or nursing women.The primary endpoint of the study is catheter occlusion evaluated by time to first observed occlusion from VC placement. Secondary endpoints include clearance of ventricular blood as measured by head CT scan, rates of catheter-related infection and shunt dependency, length of intensive care unit stay, functional status—Extended Glascow Outcome Scale (eGOS) and modified Rankin scale (mRS) at discharge to rehabilitation and 90 days—and mortality rates at 30 days and 90 days.DiscussionWith no standardized treatment for IVH and a poor prognosis, new treatments are needed. IVH patients often need CSF drainage to treat hydrocephalus and to decrease ICP. Standard treatment with passive external ventricular drainage is related to an increased risk of infections which is found in up to 22% of treated cases. The passive VC is known to have a risk of occlusion and is seen in 19–47% of the cases.We hypothesize that the use of active fluid change using the IRRAflow system will be safe and feasible and will reduce the occlusion and infection rates in patients with IVH.Trial registrationClicalTrials.gov NCT05204849.

Lower serum cystatin C level predicts poor functional outcome in patients with hypertensive intracerebral hemorrhage independent of renal function

We explored the association between the serum level of cystatin C (CysC) at admission and short-term functional outcome in patients with hypertensive intracerebral hemorrhage (HICH) without chronic kidney disease (CKD). A total of 555 patients with HICH were consecutively recruited after admission and were followed-up for 3 months after admission. The primary outcome was poor functional outcome (modified Rankin Scale [mRS] score ≥ 3). The median serum CysC level in our cohort was 1.03 mg/L (interquartile range, .89-1.20). Patients were categorized into four groups according to the serum CysC quartiles. Multivariate logistic regression analysis revealed a negative association between serum CysC and poor functional outcome at 3-month follow-up (quartile [Q]1 vs. Q4: adjusted odds ratio [OR] = .260, 95% confidence interval [CI] = .098, .691, p < .001). The negative association between serum CysC and poor functional outcome at 3 months was more pronounced in subgroups with smaller hematoma volume (≤ 30 mL), and absence of secondary intraventricular hemorrhage (IVH). Addition of serum CysC to a model containing conventional risk factors improved the model performance with net reclassification index (NRI) of .426% (p < .001) and integrated discrimination improvement (IDI) of .043% (p < .001) for poor functional outcome. Serum CysC was found to be a negative predictor of poor short-term functional outcome in HICH patients independent of renal function.

Integral neuroimaging criteria for predicting the outcome of the acute period of spontaneous supratentorial intracerebral hemorrhage on the background of conservative therapy

The aim of the study was to develop criteria for predicting the outcome of the acute period of spontaneous supratentorial intracerebral hemorrhage (SSICH) on the background of conservative therapy, taking into consideration the lesion localization in conjunction with neuroimaging parameters of the quantitative severity assessment of the damage to cerebral structures. Materials and methods. Prospective cohort examination of 314 patients in acute period of SSICH on the ground of conservative treatment. Clinical and neurological examination consisted of using the Full Outline of Unresponsiveness coma scale and NIHHS, neuroimaging with the help of computed tomography with detection of SSICH localization, volume of intracranial hemorrhage, secondary intraventricular hemorrhage and midline shift. Disease acute period outcome was evaluated on the 21st day by the Rankin scale. Results. It was detected that integrated neuroimaging SSICH’s type considering its localization and quantitative severity estimation of cerebral structure injury was closely associated with the disease acute period outcome on the ground of conservative therapy (χ2 Pearson = 308.6, Р &lt; 0.0001). Thus, mortality rate was the highest in patients with posteromedial type of thalamic hemorrhage (50.0 %), global type of thalamic hemorrhage (91.7 %) and massive type of striatocapsular hemorrhage (89.8 %). Unfavorable functional outcome as the modified Rankin scale score 4–5 on 21st disease day predominated among patients with posterolateral types of thalamic hemorrhage (76.5 %) and striacapsular hemorrhage (64.3 %). Whereas the frequency of favorable outcome was the highest among patients with anterior/dorsal type of thalamic hemorrhage (100.0 %), posteromedial (88.0 %), middle (95.0 %), lateral types of striatocapsular hemorrhage (61.9 %) and lobar (74.5 %) hemorrhage. Conclusions. Posteromedial type of thalamic hemorrhage, global type of thalamic hemorrhage and massive type of striatocapsular hemorrhage are the predictors of lethal outcome of the acute period of SSIСH on the background of conservative therapy. Criteria for unfavorable short-term functional outcome are posterolateral types of thalamic and striatocapsular hemorrhage, while anterior/dorsal type of thalamic hemorrhage, posteromedial/middle type of striatocapsular hemorrhage and lobar hemorrhage are associated with favorable outcome of the acute period of the disease.

Changes of Electrocardiogram and Myocardial Enzymes in Patients with Intracerebral Hemorrhage.

Purpose Cardiac complications are common in patients with spontaneous intracerebral hemorrhage (ICH). The present study is aimed at observing the incidence of cardiac complications after ICH, so as at improving the understanding of the relationship between cardiac complications and ICH. Methods This is a retrospective study on analyzing electrocardiogram (ECG) and serum myocardial enzyme of 208 patients with ICH admitted to a tertiary hospital from 2018 to 2019. For each patient, demographics, medical history, clinical presentation, ECG, serum myocardial enzyme, and head CT on admission were reviewed. Mortality was noted. Results Among the 208 patients, 145 (69.71%) had one or more ECG abnormalities. The top three abnormalities were corrected QT interval (QTc) prolongation 52 (25%), ST depression 48 (23.08%), and T wave inversion 38 (18.27%). One hundred and thirty-nine patients (66.83%) had increased serum levels of at least one kind of myocardial enzyme, which were high-sensitive cardiac troponin T (hs-cTnT) 79 (37.98%), lactic dehydrogenase (LDH) 80 (38.46%), creatine kinase (CK) 57 (27.40%), and creatine kinase-myocardial subfraction (CKMB) 57 (27.40%). The logistic regression analysis showed the following: secondary intraventricular hemorrhage (SIVH) (odds ratio (OR) 5.32; 95% confidence interval (CI) 2.55–11.08; p < 0.001) and hematoma volume > 30 ml (OR 3.81; 95% CI 1.86–7.81; p < 0.001) were independent predictive factors of QTc prolongation; thalamus location (OR 5.79; 95% CI 1.94–17.28; p < 0.05), hematoma volume > 30 ml (OR 24.187; 95% CI 3.14-186.33; p < 0.05), insular involvement (OR 19.08; 95% CI 5.77-63.07; p < 0.001), and SIVH (OR 2.62; 95% CI 1.69-5.86; p < 0.05) were independent predictive factors of ST depression; insular involvement (OR 2.90; 95% CI 1.12–7.50; p < 0.05) and hematoma volume > 30 ml (OR 1.98; 95% CI 1.06–3.70; p < 0.05) were independent predictive factors of increase of CK; Glasgow Coma Scale (GCS) (OR 0.86; 95% CI 0.78–0.98; p < 0.05) and insular involvement (OR 5.56; 95% CI 1.98–15.62; p < 0.05) were independent predictive factors of increase of CKMB; SIVH (OR 2.05; 95% CI 1.07–3.92; p < 0.05) was independent predictive factor of increase of LDH; age (OR 1.03; 95% CI 1.01–1.06; p < 0.05), blood glucose on admission (OR 1.10; 95% CI 1.01–1.20; p < 0.05), and history of antiplatelet drug use (OR 3.50; 95% CI 1.01–12.12; p < 0.05) were independent predictive factors of hs-cTnT. All the injury indexes were not related to in-hospital mortality. Conclusion The study suggests that insular involvement, hematoma volume > 30 ml, and SIVH are the strongest risk factors for ECG abnormalities and elevated myocardial enzymes after ICH followed which are the risk factors such as GCS, age, admission blood glucose, and ICH location in the thalamus.

Associations between Intensive Lipid-lowering Therapy and Outcomes of Intracerebral Hemorrhage

Background: The intensive lipid-lowering therapy (ILLT), targeting an low-density lipoprotein cholesterol (LDL-C) &lt; 1.80 mmol/L, was a crucial strategy for the secondary prevention of cerebrovascular diseases. But the associations between ILLT and the outcomes after intracerebral hemorrhage (ICH) were unclear. Materials and Methods: Data of the consecutive patients with acute ICH and past medical histories of ischemic stroke from 2017 to 2019 at an academic stroke center in China were analyzed. The study patients were classified according to their baseline LDL-C levels: &lt; 1.80 mmol/Lvs. ≥ 1.80 mmol/L. The outcomes of ICH were compared between the two groups. Multivariate linear mixed effect model with repeated measures adjusting for ICH scores were used to determine the associations between LDL-C levels and the change in NIHSS scores; baseline ICH scores were adjusted in the multi-variable models Results: A total of 197 patients were included in the study, 31 of them had LDL-C &lt; 1.80 mmol/L and 166 had LDL-C ≥ 1.80 mmol/L. We did not test any significant differences regarding the demographic characteristics or vascular risk factors. Medians of the baseline National Institutes of Health Stroke Scale (NIHSS) scores (8 vs. 9, P = 0.79) and ICH scores (1 vs.1, P = 0.26) were similar. But the patients with LDL-C &lt; 1.80 mmol/L had higher risks of secondary intraventricular hemorrhage (13% vs. 4%, P = 0.03). Outcomes of the hemorrhagic stroke at discharge were similar, except the patients with LDL-C ≥ 1.80 mmol/L had significant improvements in their NIHSS scores at discharge (estimated change in means: -2.4, 95% CI: [-4.3, -0.5]), while patients with LDL-C &lt; 1.80 mmol/L did not (estimated change in means: -1.4, 95% CI: [-5.9, 3.0]). Conclusion: ILLT achieved LDL-C &lt; 1.80 mmol/L was associated with limited improvements in the neurological deficits in the patients with ICH.

Prognostic value of serum S100B concentration in patients with acute spontaneous supratentorial intracerebral hemorrhage

Aim of the work – to evaluate the informativeness of serum protein S100B levels in detection of short-term prognosis in patients with acute period of spontaneous supratentorial intracerebral hemorrhage (SSICH) on the background of concervative therapy. Materials and methods. Prospective cohort study of 90 patients with acute SSICH on the background of conservative therapy was done. Level of neurological deficit was evaluated using Full Outline of Unresponsiveness Scale, Glasgow Coma Scale and National Institute of Health Stroke Scale. Computed tomography was done to detect the intracerebral hemorrhage volume (ICHV), secondary intraventricular hemorrhage volume (SIVHV) and total volume of intracranial hemorrhage (TVICH). Laboratory blood samples were taken within 24 hours of hospitalization. Levels of S100B protein in serum were measured using immunoassay analysis. Unfavorable variants of course (early neurological deterioration (END) during 48 hours from hospitalization) and disease acute period outcome of ICH (modified Rankin score 4–6 on the 21st day of the disease) were considered as endpoints. Statistical processing of the obtained results included correlation analysis, logistic regression analysis and ROC-analysis. Results. Neurological deterioration during 48 hours after hospitalization was detected in 18 (20.0 %) patients, unfavorable SSICH acute period outcome was revealed in 49 (54.4 %) patients. It was detected that serum S100B protein correlates with ICHV (R = 0.34, P ˂ 0.01), SIVHV (R = 0.39, P ˂ 0.01) and TVICH (R = 0.45, P ˂ 0.01). Thus, the patients with unfavorable SSICH acute period course and outcome are characterized with the higher S100B protein levels (P ˂ 0.0001). High sensitive multipredicive logistic regression model that integrates prognostic value of serum of S100B protein concentration with informativeness of clinical, neurological parameters (National Institute of Health Stroke Scale score, SIVHV) was elaborated. It helps to detect the individual risk of unfavorable acute SSICH period outcome on the ground of conservative therapy with the accuracy 90.0 % (AUC ± SE (95 % CІ) = 0.95 ± 0.02 (0.89–0.99), P ˂ 0.0001). Conclusions. Serum S100B protein levels in patients with SSICH on the 1st day after hospitalization is the informative additional parameter in verification of short-term prognosis on the background of conservative therapy.

Прогностична цінність сироваткової концентрації васкулярного ендотеліального фактору росту а у пацієнтів в гострому періоді спонтанного супратенторіального внутрішньомозкового крововиливу

The aim of the study – to evaluate the informativeness of serum vascular endothelial growth factor A levels in detection of short-term prognosis in acute period of spontaneous supratentorial intracerebral hemorrhage on the ground of conservative treatment. Materials and methods. Prospective cohort comparative study of the 89 patients in acute period of spontaneous supratentorial intracerebral hemorrhage was done on the ground of conservative treatment. The evaluation of neurological deficit level was performed by using Full Outline of Unresponsiveness coma scale, Glasgow scale and National Institute of Health Stroke Scale. Cerebral brain structures visualization was made by computed tomography. During 24 hours of hospitalization serum samples were collected and vascular endothelial growth factor A (VEGF-A) was measures by using ELISA method. Early neurological deterioration and unfavorable acute spontaneous supratentorial intracerebral hemorrhage period outcome (4-6 score by modified Rankin scale on the 21st day of the disease) were registered as combined clinical endpoints. Statistical operation was made with the help of correlation analysis, logistic regression analysis, ROC-analysis. Results. Patients with unfavorable course and spontaneous supratentorial intracerebral hemorrhage acute period outcome were characterized by higher serum VEGF-A values on the 1st day from admission, that correlates with the volume of intracerebral hemorrhage (R=0,21, p˂0,01), volume of secondary intraventricular hemorrhage (R=0,29, p˂0,01) and total volume of intracranial hemorrhage (R=0,31, p˂0,01). It was detected that evaluation of VEGF-A serum concentrations together with neurovisualization parameters (midline shift severity, volume of secondary intraventricular hemorrhage) as a part of multipredictive logistic regression model allow to detect individual risk of early neurological deterioration with the accuracy 89,9% (AUC±SE (95% CI) = 0,91±0,04 (0,83-0,96), р˂0,0001). Conclusions. Serum VEGF-A levels in patients with spontaneous supratentorial intracerebral hemorrhage on the 1st day from admission is an informative additional parameter for prognosis of early neurological deterioration on the ground of conservative treatment

Diagnostic and prognostic value of serum hepcidin concentration in patients with acute spontaneous supratentorial intracerebral hemorrhage

The aim of the study was to evaluate the diagnostic and prognostic value of serum hepcidin concentration in patients with acute spontaneous supratentorial intracerebral hemorrhage (SSICH). Materials and methods. Prospective cohort study of 88 patients with acute SSICH receiving the conservative therapy was conducted. Level of neurological deficit was evaluated using the Full Outline of UnResponsiveness Scale, the Glasgow Coma Scale and the National Institute of Health Stroke Scale. Computed tomography was performed to detect an intracerebral hemorrhage volume (ICHV), secondary intraventricular hemorrhage volume (SIVHV) and total volume of intracranial hemorrhage (TVICH). Laboratory blood samples were taken within 24 hours of hospitalization. Hepcidin levels, serum iron concentrations and total iron-binding capacity were determined, followed by calculations of transferrin saturation coefficient. Early neurological deterioration (END) and unfavorable variants of the acute period of SSICH (lethal outcome, modified Rankin score 4-5 on the 21st day of the disease) were considered as endpoints. Statistical processing of the obtained results included a correlation analysis, logistic regression analysis and ROC-analysis. Results. It was identified, that serum hepcidin level in the patients with SSICH was correlated with ICHV (R = 0.44, P ˂ 0.01), SIVHV (R = 0.45, P ˂ 0.01) and TVICH (R = 0.57, P ˂ 0.01). Hepcidin serum concentrations in the patients with ICHV &gt;30 ml exceeded the value of those in cases of ICHV ≤30 ml by 69.0 % (P ˂ 0.0001). Serum levels of hepcidin were significantly higher in the patients with an unfavorable course and outcome of the disease in the acute period on the 1st day of admission (P ˂ 0.0001). Informative multipredictor models were developed via multiple logistic regression analysis, which include hepcidin values coupled with clinical and neurovisualization findings and are predictive of lethal and unfavorable acute period functional outcomes (AUC = 0,93, P ˂ 0.0001). Conclusions. The level of serum hepcidin in patients with acute SSICH is associated with the severity of cerebral lesions. The integration of serum hepcidin concentration with clinical and neuroimaging findings in the structure of multipredictor logistic regression models allows to determine the vital and functional prognosis of the acute period of SSICH with an accuracy of &gt;85 %

Abstract P462: Intensive Lipid Lowering Therapy May Lead to Worse Outcomes of Intracerebral Hemorrahge

Background: Intensive Lipid-lowering therapy (ILLT) is a crucial strategy for secondary prevention of ischemic stroke. While current evidence of the risks of intracerebral hemorrhage (ICH) after ILLT were contradictory; morever, insights into the associations between ILLT and the outcomes of ICH were also limited. Methods: Data of consecutive patients with acute ICH and histories of ischemic stroke at an academic stroke center from 2017 to 2019 were retrospectively collected. The study patients were classifed according to their baseline low-density lipoprotein cholesterol (LDL-c) levels: &lt;1.8 mmol/L vs. LDL-c≥1.8 mmol/L. Results: A total of 197 patients were included in the study, 31 of them had LDL-c &lt;1.8 mmol/L and 166 had LDL-c≥1.8 mmol/L. We did not tested any significant differences regarding the demographic characteristics or the medical histories (Table 1). Medians of baseline National Institutes of Health Stroke Scale (NIHSS) scores (8 vs. 9, p=0.79) and ICH scores (1 vs.1 , p=0.26) were similar. But patients with LDL-c&lt;1.8 mmol/L had higher bleeding volume (11 (19) vs. 10 (52), p=0.03) and higher risks of secondary intraventricular hemorrhage (13% vs. 4%, p=0.03) (Table 2).Outcomes of the ICH events at discharge were generally similar (Table 3), except that patients with LDL-c≥1.8 mmol/L had significant improvements in their NIHSS scores at discharge (estimated change in means: -2.4, 95% [-3.9, -0.9] ), than patients with LDL-c&lt;1.8 mmol/L (estimated change in means: -1.4, 95% CI [-4.7, 0.5]). Conclusions: Achieving LDL-c&lt;1.8 mmol/L was associated with bigger bleeding volume, higher risks of secondary intraventricular hemorrhage, and worse neurological improvements.

To Investigate the Effect of Catheter Drainage and Urokinase Dissolution for Severe Ventricular System Hemorrhage

Objective: To investigate the decrease of mortality and disability rate of severe ventricular system hemorrhage by catheter drainage and UK dissolution. Methods: From January 2015 to January 2020, 78 cases of primary severe ventricular hemorrhage and 47 cases of thalamic hematoma had broken into the ventricular system by admitted, all of which were caused by hypertension arteriosclerosis. A respectively adopt the double eminence F10 silicone tube line hemorrhage or hemorrhage drainage, drain and intraoperative all press automatic drainage device, and at the same time CT directional line thalamic hematoma drainage, pipe emptying and postoperative introcerebral hematoma and interior cavity at different times each injection urokinase solute 30000-50000 units, and lumbar puncture or with lumbar cistem catheter drainage, large cavity of thalamic hematoma and the original secondary intraventricular hemorrhage drainage time respectively for 3-4 d and 4-5 d, an average of 4.5 d extubation time. Results: After 6 months of follow-up, GOS and ADL grading were used to evaluate the recovery and self-care ability. GOS grading was 5points in 72 cases, 4 points in 41 cases, 3 points in 12 cases. ADL grading was Grade I in 69 cases, Grade II in 40 cases, Grade III in 5 cases, Grade IV in 6 cases, and Grade V in 5 cases (including 3 deaths). Among the 3 cases who died after operation, either 2 case suffered from primary whole ventricular hemorrhage combined with cerebral hernia, 1 case suffered from secondary hemorrhage combined with respiratory and circulatory failure caused by dilated hemocast of four ventricles. Sometime whith association communicating hydrocephalus in 3 cases that is underwent brain-peritoneal cerebrospinal fluid shunt. Conclusion: Empty and drainage of ventricular system hemorrhage and paraventricular thalamic hematoma which is can significantly reduce the morbidity and mortality.

PREDICTORS OF EARLY NEUROLOGICAL DETERIORATION IN PATIENTS WITH ACUTE SPONTANEOUS SUPRATENTORIAL INTRACEREBRAL HAEMORHAGE

This study was designed in order to improve diagnostic approaches in acute period of spontaneous intracerebral haemorrhage based on the elaboration of prognostic criteria for detecting early neurological deterioration under the conservative treatment. This prospective study included 339 patients having the first intracerebral haemorrhage. Clinical neurological examinations were carried out over the course of acute period of the disease by using Full Outline of UnResponsiveness scale and National Institute of Health Stroke Scale. The volume of intracerebral and secondary intraventricular haemorrhage, presence and severity of midline shift were detected by neurovisualizing techniques. Early neurological deterioration was chosen as a cumulative endpoint. We considered the signs of deterioration under the therapy during the first 24 – 48 hours following the admission to the hospital: decrease in Full Outline of UnResponsiveness scale score ≥2; increase in the National Institute of Health Stroke Scale score ≥4; lethal outcome. Logistic regressive analysis and ROC-analysis were used for elaboration of the prognostic criteria. Results. Neurological deterioration under the conservative therapy for 24 – 48 hours since the hospitalization was detected in 29,2-33,6% of cases. Multiple logistic regression analysis showed that initial degree of midline shift and volume of secondary intraventricular haemorrhage are the most informative parameters for evaluating risk of early neurological deterioration in patients with hemorrhagic stroke, who received the conservative therapy.&#x0D; The volume of secondary intraventricular hemorrhage &gt;13,5 ml (sensitivity 70,5-72,7%, specificity 80,8-82,8%) and mean value of septum pellucidum and pineal gland shift &gt;4,5 mm (sensitivity 60,6-60,7%, specificity 85,8-89,2%) were the predictors for early neurological deterioration. The above-mentioned predictors were integrated into the mathematical models for early neurological deterioration prognosis during 24 hours (AUC (95% CІ) = 0,85 (0,81-0,89), р˂0,0001) and 48 hours since the hospital admission (AUC (95% CІ) = 0,87 (0,83-0,90), р˂0,0001). Conclusions. The informative neurovisualization criteria for early neurological deterioration in patients with spontaneous supratentorial intracerebral haemorrhage were elaborated. They include the integrated degree of midline shift and the volume of secondary intraventricular hemorrhage. These criteria enable to determine the individual cumulative risk of unfavorable outcomes of acute period of the disease under the conservative therapy following 24 – 48 hours since the hospitalization with the accuracy of 81,7-82,9%.

Early neurological deterioration prediction in patients with hemorrhagic hemispheric stroke on the ground of quantitative evaluation of secondary interventricular hemorrhage severity

The early neurological deterioration criteria in patients with hemorrhagic hemispheric stroke (HHS) were elaborated on the ground of quantitative evaluation of secondary interventricular hemorrhage (IVH) severity. The prospective study with 339 patient’s involvement with the participation of patients with an average age (64.8±0.6) years old with spontaneous (hypertensive) supratentorial intracerebral hemorrhage. The diagnosis was made by brain computed tomography with quantitative evaluation of secondary intraventricular hemorrhage severity by using Graeb, Leroux and Intraventricular Hemorrhage (IVH). Early neurological deterioration (END) was taken as a combined clinical end-point. END was detected as one of the following criteria onset: reduction of the summary score according to Full Outline of UnResponsiveness coma scale &gt; 2; increasing of the summary score on National Institute of Health Stroke Scale &gt; 4; lethal outcome. Statistic processing of the results was made with the use of Mann-Whitney criteria and ROC-analysis. Combined clinical end-point was registered in 29.2 % cases. It was detected that patients with END are characterized with higher values of summary score according to Graeb (7 [4–8] vs 0 [0–4], p&lt;0.0001), Leroux (9 [5–12] vs 0 [0–5], p&lt;0.0001) and IVH scales (17 [13–20] vs 0 [0–12], p&lt;0.0001). While the mentioned scales do not differ in diagnostic informativeness when individual END detection prognosis in patients with HHS (AUC is 0.80-0.81). Summary score according to Graeb &gt; 5 (Se = 68.7%, Sp = 82.9%), Leroux &gt; 4 (Se = 76.8%, Sp = 74.6%) and IVH &gt; 13 (Se =72.7%, Sp = 80.8%) scales are predictors of END in patients with HHS. It was detected that in case of FOUR score &lt; 13, volume of intracerebral hemorrhage &gt; 40 ml and midline shift &gt; 5 mm, positive predictive value of these criteria exceeds 90%, while in general cohort – does not reach 65%. The threshold values of summary score in Graeb, Leroux and IVH scales are the informative criteria of END prognosis in patients with HHS.

Early Administration of Desmopressin and Platelet Transfusion for Reducing Hematoma Expansion in Patients With Acute Antiplatelet Therapy Associated Intracerebral Hemorrhage.

To investigate the hemostatic efficacy of combined desmopressin (1-deamino-8-D-arginine vasopressin) and platelet transfusion in reducing hematoma expansion in acute, spontaneous intracerebral hemorrhage under antiplatelet treatment. Single-center, nonrandomized study, performed between 2006 and 2014. Tertiary University Hospital of Tuebingen, Germany. Adult patients with intracerebral hemorrhage under antiplatelet treatment and follow-up CT at 24 ± 12 hours were included. Exclusion criteria included other intracerebral hemorrhage causes, anticoagulation, coagulopathy, or immediate surgery after baseline-CT. Treatment with IV 1-deamino-8-D-arginine vasopressin (0.4 µg/kg) + platelet transfusion (2 U) within 60 minutes of intracerebral hemorrhage under antiplatelet treatment diagnosis on brain imaging. Primary outcome was relative hematoma expansion from baseline to follow-up CT. Secondary outcomes included secondary intraventricular hemorrhage or hydrocephalus upon follow-up CT, thromboembolic events before discharge, and the 3-month functional outcome (assessed by modified Rankin Scale). One-hundred forty patients were included, 72 treated versus 68 controls. Times of symptom-onset-to-baseline-CT (hr) (median [interquartile range]: 3 [4] vs 5 [5]; p = 0.468) and follow-up CT (26 [18] vs 19 [12]; p = 0.352) were similar between groups. No between-group differences of total intracerebral hematoma expansion (%) (median [interquartile range]: 8.5 [12.4] vs 9.1 [16.5]; p = 0.825), intraparenchymal (10.7 [23.1] vs 9.2 [20.7]; p = 0.900), and intraventricular hematoma expansion (14.5 [63.2] vs 6.1 [40.4]; p = 0.304) were noted. Among patients with hematoma expansion greater than or equal to 33% compared with baseline, 16 (52%) received treatment versus 15 (48%) controls. The occurrence of hematoma expansion greater than or equal to 33% was similar between groups (p = 0.981). Rates of secondary intraventricular hemorrhage, hydrocephalus, and thromboembolic events were similar between groups. Treatment with 1-deamino-8-D-arginine vasopressin + platelet transfusion was not associated with the 3-month functional outcome (adjusted odds ratio, 1.570; 95% CI, 0.721-3.419; p = 0.309). In line with the randomized Platelet Transfusion Versus Standard Care After Acute Stroke Due to Spontaneous Cerebral Hemorrhage Associated With Antiplatelet Therapy trial, our results suggest no hemostatic efficacy of early platelet transfusion in intracerebral hemorrhage under antiplatelet treatment. Contrary to results of preclinical and clinical nonintracerebral hemorrhage studies, adjunct 1-deamino-8-D-arginine vasopressin showed no benefit in limiting hematoma expansion or improving functional outcome.
