Usefulness of antegrade foam sclerotherapy for portal hypertensive variceal bleeding.

This study investigates the usefulness of antegrade variceal embolization using sclerosant foam to evaluate technical success and clinical outcomes in cases of hypertensive variceal bleeding. A total of 16 patients underwent percutaneous antegrade variceal embolization using foam sclerotherapy from August 2019 to January 2022. Among the patients, 12 cases were of gastroesophageal varices, two were rectal varices, and one case each was duodenal and jejunal varices, respectively. Sodium tetradecyl sulfate (STS) foam was used as a detergent for variceal bleeding sclerotherapy at various anatomical locations. The detergent was used in a foam form to promote clinical outcomes and enable the effective embolization of the entire blood vessel wall, including the ventral side, against gravity. Furthermore, STS foam could be used to help sufficiently deliver the drug to distal segments. A balloon catheter was also used to block the antegrade flow and prevent the dilution of the sclerosant. Technical success was defined as the completion of sclerotherapy for variceal bleeding as planned before the procedure to achieve the disappearance of variceal bleeding. Clinical success was defined as the complete obliteration of varices without recurrent bleeding during the follow-up period after the procedure. Technical success was 81.3%, and clinical success was 84.6%. Additionally, 15/16 of the procedures were emergencies, and there were no complications related to the procedure. Antegrade foam sclerotherapy using 3% STS for variceal bleeding is clinically safe and effective. Moreover, antegrade foam sclerotherapy can be a useful treatment option for patients with active variceal bleeding in emergency cases.

Analysis of the prognosis and survival of patients with acute-on-chronic liver failure

Objective: To explore the influencing factors and the impact of artificial liver treatment on the prognosis and survival of patients with acute-on-chronic liver failure (ACLF). Methods: Clinical data from 201 cases with ACLF from January 2016 to December 2019 was retrospectively analyzed. The survival rate was calculated by the Kaplan-Meier method, the log-rank test of univariate analysis, and the multivariate analysis of the stepwise Cox regression forward method. Results: The median survival time of patients was 6 months, and the survival rates at 6, 9, and 12 months were 51.2%, 38.3%, and 29.9%, respectively. In univariate analysis, age, presence or absence of hypertension and upper gastrointestinal bleeding, treatment method, model for end-stage liver disease (MELD) score, and cholinesterase were associated with prognosis (P < 0.05). Multivariate regression analysis results showed that MELD score was the main factor affecting the 1-year prognosis of ACLF patients (P = 0.002). Artificial liver treatment was beneficial for the 1-year prognosis of ACLF patients aged < 50 years or with a MELD score of ≥20 (P < 0.05 ). The relative risk ratio (RR) of mortality was 2.55 times higher in patients with advanced age (≥50 years old) than that of younger patients (P < 0.001). Regression analysis was performed using age as a stratification factor, and upper gastrointestinal bleeding was related to the prognosis of younger patients, while choline esterase was related to the prognosis of advanced age. Regression analysis after stratified MELD score showed that age and hypertension were related to the prognosis of patients with MELD score < 20, and treatment method and age were related to the prognosis of patients with MELD score≥20. Conclusion: Artificial liver treatment is beneficial for the 1-year prognosis of ACLF patients. Age, MELD score, hypertension, and upper gastrointestinal bleeding are independent risk factors affecting the prognosis of ACLF patients.

An excerpt from the 2023 AASLD practice guidelines: TIPS, variceal embolization, and retrograde transvenous embolization for the treatment of variceal hemorrhage

This is the American Association for the Study of Liver Diseases (AASLD) comprehensive guideline on the application of endovascular interventional radiological procedures in the treatment of variceal bleeding, which supplements Risk Stratification and Management of Portal Hypertensive Bleeding in Cirrhosis by describing recent advances in invasive surgery. Transjugular intrahepatic portosystemic shunt (TIPS) dates back to the 80s of the 20th century, and over the past few years, several new technical improvements have been made to TIPS stents. Another major treatment for gastric variceal bleeding in North America is the use of different forms of retrograde transvenous embolization. This guideline is intended to provide healthcare professionals with an in-depth understanding of the use of TIPS and/or variceal embolization/occlusion in the treatment of variceal bleeding, with the goal of facilitating multidisciplinary discussions on treatment strategies among hepatologists, gastroenterologists, interventional radiologists, and surgeons. Additionally, it provides a data-based approach to the endovascular treatment of variceal bleeding. However, it differs from the AASLD guidelines by being supported by a systematic review of the literature, a formal rating of the quality of the evidence, and the strength of the recommendations. Consequently, this guideline was developed by a consensus of an expert panel under the supervision of the AASLD Practice Guidelines Committee and provides guidance statements based on a comprehensive review and analysis of the literature on the relevant topic. Importantly, the AASLD Practice Guidelines Committee selected this topic because, for the most part, there are not a sufficient number of randomized controlled trials on this topic to provide meaningful systematic reviews and meta-analyses.

Nasoenteric Tube Placement in Patients with Esophageal Varices: A Review of the Current Evidence and Society Guidelines.

Esophageal varices are a common complication of portal hypertension and variceal bleeding can be associated with significant morbidity and mortality. Hospitalized patients with cirrhosis might require nasoenteric tube (NET) placement, commonly for nutritional support and/or medication administration. However, the fear of causing massive variceal bleeding among clinicians might lead to hesitancy or complete avoidance of NET placement in patients who either have a known history of esophageal varices or are at risk to have them. Several experts and society guidelines addressed this concern with variable recommendations and degrees of evidence. In this article, we present an extensive review of the literature and latest society guidelines that address the safety of NET placement in patients with esophageal varices.

Transhepatic ultrasound guided embolization as a successful novel technique in treatment of pediatric complex intrahepatic arterioportal fistula: a case report and review of the literature

IntroductionIntrahepatic vascular shunts “IHVS” are abnormal communications between intra-hepatic vasculature involving the arterial, portal, or hepatic venous system. Arterio-portal fistula “APF” is an intrahepatic communication between the hepatic arterial system and the portal venous system without any communication with the systemic venous circulation. APF is considered a rare cause of portal hypertension and gastrointestinal bleeding in infancy.Case presentationA 3-month-old Mediterranean female with known cardiac congenital anomalies presented to us with abdominal distension and diarrhea. Ultrasonography revealed massive ascites and computerized tomography (CT) abdomen with intravenous (IV) contrast revealed a left hepatic lesion. On further evaluation, an intrahepatic arterio-portal vascular malformation was detected. Attempted trans arterial embolization failed and radiology team successfully carried out direct trans hepatic ultrasound guided coiling of the aneurysmal venous sac followed by successful resection of segment 4 of the liver with the vascular malformation avoiding life threatening intra operative bleeding.ConclusionAny child with recurrent gastrointestinal bleeding, failure to thrive, vomiting, diarrhea, steatorrhea, splenomegaly, or ascites should be investigated for intrahepatic arterio-portal fistula “IAPF”. Our novel technique of direct trans hepatic ultrasound guided coiling is an alternative method if trans arterial embolization “TAE” failed.

Describing Trends in Maternal Mortality in the State of São Paulo, Brazil, from 2009 to 2019.

Maternal mortality is a significant public health concern, with varying impacts across different regions in Brazil, particularly affecting women from lower-income social classes with limited access to social resources. The aim of this study is to describe the trends in maternal mortality in São Paulo, Brazil, from 2009 to 2019. This study employed an ecological approach utilizing a time-series design to examine maternal deaths. Secondary data from the Mortality Information System (SIM) and the Live Births Information System (SINASC) from 2009 to 2019 were utilized. The analysis included all maternal deaths among women aged 10 to 49 years residing in the state of São Paulo. Time-series data for maternal mortality ratios were constructed for the seven regions within São Paulo State. Joinpoint regression analysis was applied to characterize the maternal mortality ratio. The study estimated the annual percentage variation, the average annual percentage variation, and their respective 95% confidence intervals. In São Paulo, a total of 3075 maternal deaths were reported, resulting in a mortality ratio of 45.9 deaths per 100,000 live births. The leading causes of maternal death were eclampsia (7.13%), gestational hypertension (6.09%), and postpartum hemorrhage (5.89%). The analysis of the annual percentage change in the maternal mortality ratio for São Paulo State and its six clusters showed stationarity. The assessment of the maternal mortality ratio in the state of São Paulo, Greater São Paulo, and Baixada Santista revealed an increase in the maternal death ratio over the studied period.

Pregnancy by Oocyte Donation: Reviewing Fetal-Maternal Risks and Complications.

Oocyte donation (OD) has greatly improved over the last three decades, becoming a preferred practice of assisted reproductive technology (ART) for infertile women wishing for motherhood. Through OD, indeed, it has become possible to overcome the physiological limitation due to the ovarian reserve (OR) exhaustion as well as the poor gamete reliability which parallels the increasing age of women. However, despite the great scientific contribution related to the success of OD in the field of infertility, this practice seems to be associated with a higher rate of major risky events during pregnancy as recurrent miscarriage, infections and placental diseases including gestational hypertension, pre-eclampsia and post-partum hemorrhage, as well as several maternal-fetal complications due to gametes manipulation and immune system interaction. Here, we will revisit this questioned topic since a number of studies in the medical literature focus on the successful aspects of the OD procedure in terms of pregnancy rate without, however, neglecting the risks and complications potentially linked to external manipulation or heterologous implantation.

Endoport Assisted Endoscopic Surgery for Hypertensive Basal Ganglia Hemorrhage by Transsylvian Approach: Technical Nuances and Preliminary Clinical Results

There is no clear evidence on the indication and surgical approaches on evacuating basal ganglia hemorrhage caused by hypertensive bleeding. Some studies have shown that minimally invasive approaches have therapeutic potentials, but its benefits remain inconclusive. We describe an endoport assisted endoscopic transsylvian approach for basal ganglia hemorrhage evacuation. We evaluate the safety and efficacy of this approach in a cohort study. We included 19 patients (mean age 57years) who underwent the surgery at a single county-level hospital in Yunan Province, China. The majority had a Glasgow coma scale between 9 and 12 on admission. The midline shift ranged from 16-29mm (mean 19mm). Hematoma volume ranged from 46 to 106ml (mean 67ml). Six patients (31.6%) presented with intraventricular hemorrhage. All patients achieved greater than 90% decrease in hematoma volume at postoperative computed tomography scan. The average operative time was 115 minutes and average blood loss of 44ml. The most common postoperative complication was pulmonary infection (63.2%). No rebleeding, seizure, infectious meningitis, or postoperative mortality was observed. A total of 17 patients (89.5%) achieved good functional recovery at follow up within 90days after surgery (Glasgow outcome scale 4-5) and 2 patients had severe disability (Glasgow outcome scale 3). Endoport assisted endoscopic surgery through transsylvian approach is safe and effective treatment for hypertensive basal ganglia hemorrhage. The majority of patients have good functional recovery and the rate of severe complications is low.

Neuronavigation-assisted neuroendoscopy versus conventional craniotomy for hypertensive cerebellar hemorrhage: A comparative analysis of efficacy and outcomes

ObjectiveHypertensive cerebellar hemorrhage is a severe condition in neurosurgery, associated with high disability and mortality rates. The present study compares the efficacy and outcomes of neuronavigation-assisted neuroendoscopy versus conventional microscope (craniotomy) in treating patients with hypertensive cerebellar hemorrhage. MethodsA retrospective study was conducted by analyzing medical records of patients with hypertensive cerebellar hemorrhage treated at Wuhan No.1 Hospital between February 2015 and February 2019. The study included 65 patients who underwent either neuronavigation-assisted neuroendoscopy (n = 35) or conventional microscopy treatment (n = 30). All patients underwent standard neurological and clinical examinations, as well as routine laboratory tests upon admission. The diagnosis of hypertensive cerebellar hemorrhage was based on computed tomography (CT) findings. Basic parameters, clinical status on admission, imaging results, management, and outcome measures were evaluated and compared between the two groups. ResultsNeuronavigation-assisted neuroendoscopy showed advantages over craniotomy in terms of surgical procedure time and intraoperative blood loss ((81.91 ± 17.77) min vs (195.20 ± 31.97) min, (63.66 ± 12.42) ml vs (335.00 ± 104.26) ml, P < 0.01). The hematoma evacuation rate was higher in neuroendoscopy group ((94.37 ± 5.174)% compared to the craniotomy group ((90.80 ± 5.404)%, P < 0.01). Additionally, the time of ventricular drainage was shorter in the neuroendoscopy group ((4.83 ± 1.671) days) than in the craniotomy group ((7.70 ± 1.878) days, P < 0.01). Neuroendoscopy group also resulted in fewer surgical complications and a shorter hospital stay (P < 0.05). There was no significant difference in the risk of rebleeding and mortality between the neuroendoscopy and craniotomy group (P > 0.05). ConclusionNeuronavigation-assisted neuroendoscopy is a rapid, safe, and effective minimally invasive technique for the treatment of hypertensive cerebellar hemorrhage. It offers potential benefits in reducing surgical complications and hospital stay compared to conventional craniotomy.

Outcomes of Transjugular Intrahepatic Portosystemic Shunt and Gastric Coronary Vein Embolization for Variceal Bleeding in Cirrhotic Portal Hypertension.

Purpose: To evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) combined with gastric coronary vein embolization (GCVE) for cirrhotic portal hypertensive variceal bleeding and compare outcomes of first-line with second-line treatment, coil with glue, and single-covered with double stents.Methods: Fifteen patients received TIPS plus GCVE as the first-line treatment for secondary prophylaxis of variceal bleeding, and 45 received it as second-line treatment. Preoperative and postoperative quantitative variables were compared using a paired t test. The incidence of survival rate, re-bleeding, hepatic encephalopathy, and shunt dysfunction were analyzed using the Kaplan-Meier method.Results: The portal venous pressure was significantly decreased from 39.0 ± 5.0 mm Hg to 22.5 ± 4.4 mm Hg (P≤0.001) after TIPS treatment. After 1, 3, 6, 12, 18, and 24 months re-bleeding rates were 1.6%, 3.3%, 6.6%, 13.3%, 0%, and 0%, respectively. Shunt dysfunction rates were 5%, 0%, 10%, 16.6%, 1.6%, and 5%, respectively. Hepatic encephalopathy rates were 3.3%, 1.6%, 3.3%, 6.6%, 0%, and 0%, respectively. And survival rates were 100%, 100%, 100%, 96.6%, 93.3%, and 88.3% respectively. In comparative analysis, statistically significant differences were seen in re-bleeding between the first-line and second-line treatment groups (26.6% vs 24.4%, log-rank P=0.012), and survival rates between single-covered and double stent (3.7% vs 16.1%, log-rang (P=0.043).Conclusion: The results suggest that TIPS combined with GCVE is effective and safer in the treatment of cirrhotic portal hypertensive variceal bleeding. The use of TIP plus GCVE as first-line treatment, may be preferable for high-risk re-bleeding, and more than 25 mm Hg portal venous pressure with repeated variceal bleeding. However, the sample size was small. Therefore, large, randomized, controlled, multidisciplinary center studies are needed for further evaluation.

Management of upper gastrointestinal bleeding in advanced hepatocellular carcinoma with portal hypertension and variceal bleeding during receiving tyrosine kinase inhibitors therapy: Beyond and known frontiers

AbstractHepatocellular carcinoma (HCC) poses a significant global burden, with most patients being diagnosed at an advanced stage, leading to poor prognosis due to the lack of systemic treatment. The approval of oral tyrosine kinase inhibitors (TKIs), immune checkpoint inhibitors, and anti‐angiogenic agents has rapidly expanded the treatment prospects for HCC. However, the use of these drugs has also increased the incidence of portal hypertension (PHT) and upper gastrointestinal variceal bleeding in HCC patients. The diagnosis, screening, emergency treatment, and secondary prevention of upper gastrointestinal variceal rebleeding in advanced HCC patients undergoing oral TKIs therapy have become clinically urgent and critical issues. This review provides an overview of the existing understanding regarding the uses and limitations of transjugular intrahepatic portosystemic shunt (TIPS) insertion for managing HCC in cirrhosis patients with PHT and variceal hemorrhage. Additionally, it explores the potential of TIPS in managing acute upper gastrointestinal bleeding and preventing rebleeding in advanced HCC patients undergoing TKIs therapy. The placement of TIPS within the treatment hierarchy is determined by the specific clinical environment and the individual attributes of the patient.

Description and analysis of the emergency obstetric interfacility ambulance transfers (IFTs) to Kawempe National Referral Hospital in Uganda.

In Uganda, 2% of women die from maternal causes with a mortality rate of 336 maternal deaths per 100,000 live births. According to the World Health Organization Uganda is one of the top three contributors to maternal mortality in sub-Saharan Africa. Uganda has parallel weak ambulance systems, government, and non-government-owned, that transport obstetric emergencies to higher-level facilities. These two operations lack standards of medical care and inter-facility transfer (IFT) protocols to direct care. Limited studies exist which assess the state of Emergency Care Services in Uganda and none has been performed to assess the ambulance referral services utilized to address obstetric emergencies. The present study was performed to describe the ambulance transfer processes of obstetric emergencies by analyzing cases arriving at Kawempe National Referral Hospital (KNRH) from outlying health facilities. The study was based at KNRH in Kampala, Uganda. It was a descriptive and analytic cross-sectional study. Trained research assistants enrolled participating patients who met the inclusion criteria consecutively on arrival by ambulance at the hospital. Utilizing a questionnaire, quantitative data was collected from the ambulance driver, the sending facility referral form, and the receiving hospital's ambulance log book for each case. The sample size was 215. The median age was 27 years and the majority of patients were referred because of hypertensive disorders (34.9%), obstructed labor (26.5%) and hemorrhage (20.9%). The median total response time for transfer of obstetric emergencies was 50min, from ambulance activation until the mother was received at KNRH. Differences were identified between government and non-government-owned ambulances in regards to the method of activation, medical escort staffing, number of vital signs recorded, and ambulance onboard medical care. Ambulances parked at the facility took the shortest transfer time and EMT-supported ambulances had the greatest number of vital signs taken. Recommendations are to develop an integrated ambulance system for both government and non-government ambulances with standards especially in regards to standardized scripted call-center calls analysis, dispatch activation time, response-to-patient time, and trained ambulance professional staffing and medical care whenever in patient transport mode.

Histological Features of Cerebral Arteries and Brain Parenchyma in Cadavers Who Had Died from Hemorrhagic Stroke

Cerebral atherosclerosis is a risk factor for stroke. Several contents in the atheromatous plaque have been identified, but some have not yet been quantified. This is especially true for lipids. This study aims to compare the histology, vascular wall contents of the cerebral artery ipsilateral to the hemorrhagic lesion, and hemorrhagic parenchyma to that of the contralateral and the control. The A1, M1, and P1 segments of cerebral arteries from twelve stroke cadavers and those from eight control cadavers were used in this study. All segments were prepared for H&amp;E, Sudan black B, trichrome, and modified Verhoeff’s Van Gieson stains and were then analyzed for vascular parameters, lipid area, collagen area, and elastic density, respectively. The results show that the wall areas of A1 and P1 ipsilateral to hemorrhagic lesions were significantly larger than those of the contralateral. The areas of the vascular lumen of M1 ipsilateral and contralateral to the hemorrhagic lesion were significantly smaller than that of the control. The largest lipid area was found in the ipsilateral M1 among the three groups. The collagen area in the ipsilateral M1 was significantly larger than that of the control. Finally, the elastic fibers in all ipsilateral segments had significantly less density than that of the control. The nervous parenchyma contralateral to the hemorrhage was shown to be an impaired tissue. In conclusion, high accumulations of lipids and collagen, along with low elastic density in the ipsilateral M1, might have reduced the size of its lumen and its flexibility, potentially resulting in a hypertensive hemorrhage.

Secular trends and features of thalamic hemorrhages compared with other hypertensive intracerebral hemorrhages: an 18-year single-center retrospective assessment.

Trends regarding the locations of hypertensive cerebral hemorrhages are unclear. To clarify hypertensive hemorrhage trends, we investigated intracerebral hemorrhages (ICHs) over an 18-year period, focusing on thalamic hemorrhages compared with other sites of hemorrhages. We reviewed the cases of patients hospitalized for hypertensive ICH in 2004-2021 at our hospital; 1,320 eligible patients were registered with a primary ICH/intraventricular hemorrhage. After exclusion criteria were applied, we retrospectively analyzed 1,026 hypertensive ICH cases. The proportions of thalamic and subcortical hemorrhages increased over the 18-year period, whereas putaminal hemorrhage decreased. Multivariate logistic regression analyses revealed that for thalamic hemorrhage, ≥200 mmHg systolic blood pressure (p = 0.031), bleeding <15 mL (p = 0.001), and higher modified Rankin scale (mRS) score ≥ 4 at discharge (p = 0.006) were significant variables in the late period (2013-2021) versus the early period (2004-2012), whereas for putaminal hemorrhage, significant factors in the late period were triglyceride <150 mg/dL (p = 0.006) and mRS score ≥ 4 at discharge (p = 0.002). Among the features of the thalamic hemorrhages in the late period revealed by our group comparison with the putaminal and subcortical hemorrhages, the total and subcortical microbleeds were more notable in the thalamic hemorrhages than in the other two types of hemorrhage, whereas cerebellar microbleeds were more prominent when compared only with subcortical hemorrhages. Our findings revealed an increasing trend for thalamic hypertensive hemorrhage and a decreasing trend for putaminal hemorrhage. The thalamic hemorrhage increase was observed in both young and older patients, regardless of gender. The main features of thalamic hemorrhage in the late period versus the early period were decrease in larger hemorrhage (≥15 mL) and an increase in cases with higher systolic blood pressure (at least partially involved a small number of untreated hypertensive patients who developed major bleeding). The total and subcortical microbleeds were more notable in the thalamic hemorrhages of the late period than in the putaminal and subcortical hemorrhages. These results may contribute to a better understanding of the recent trends of hypertensive ICHs and may help guide their appropriate treatments for this condition.

Influencing factors of futile recanalization after endovascular therapy in acute ischemic stroke patients with large vessel occlusions

Objective: To analyze the influencing factors of futile recanalization after endovascular therapy (EVT) in acute ischemic stroke patients with large vessel occlusions (AIS-LVO). Methods: AIS-LVO patients who underwent EVT with successful recanalization between January 2019 and December 2021 in Neurovascular Center of Changhai Hospital of Naval Medical University were retrospectively selected. Modified Rankin scale (mRS) score 3 months after EVT was used as the prognostic evaluation index, and patients with mRS scores≤2 were classified as the meaningful recanalization group and mRS scores 3-6 as the futile recanalization group. The risk factors, National Institutes of Health stroke scale (NIHSS) score, Glasgow coma scale (GCS) score, Alberta Stroke Program Early CT (ASPECT) score, core infarct volume, etc. in both groups were analyzed, and the influencing factors of futile recanalization after EVT were analyzed by multivariate logistic regression. Continuous variables that do not conform to the normal distribution are represented by [M(Q1,Q3)]. Results: A total of 368 patients meeting the inclusion criteria were collected, including 228 males and 140 females, and aged 68 (61, 77) years. There are 196 patients and 172 patients in the meaningful recanalization and futile recanalization groups, respectively, with the rate of futile recanalization 3 months after EVT of 46.74% (172/368). Comparing the general information and risk factors between the two groups found that the age of patients in the futile recanalization group [71 (65, 79) years] was higher than that in the meaningful recanalization group [65 (59, 72) years]. The baseline NIHSS score [18 (14, 22)] and the rate of not achieving modified Thrombolysis in Cerebral Ischemia grade 3 (mTICI 3) reperfusion (36.1%) were higher in the futile recanalization group than those in the meaningful recanalization group [12 (7, 17) and 19.9%]. The baseline GCS score [11 (9, 13)] was lower in the futile recanalization group than that in the meaningful recanalization group [14 (11, 15)]. The core infarct volume in the futile recanalization group [28 (7, 65) ml] was larger than that in the meaningful recanalization group [6 (0, 17) ml]. The ASPECT score [7 (5, 9)] was lower in the futile recanalization group than that in the meaningful recanalization group [9 (7, 10)]. In addition, the proportion of hypertension, atrial fibrillation, general anesthesia, and symptomatic intracranial hemorrhage was higher in the futile recanalization group (all P<0.05). The time from symptom onset to puncture and from symptom onset to reperfusion was longer in the futile recanalization group (both P<0.05). There were statistically significant differences in trial of Org 10172 in acute stroke treatment (TOAST) classification and the site of occluded blood vessels between the two groups (both P<0.05). Multivariate logistic regression indicated that age ≥80 years(OR=1.935,95%CI: 1.168-3.205), baseline NIHSS score (OR=1.999,95%CI: 1.202-3.325), GCS score (OR=2.299,95%CI: 1.386-3.814), previous stroke history (OR=1.977,95%CI: 1.085-3.604), general anesthesia (OR=1.981,95%CI: 1.143-3.435), not achieving grade 3 recanalization (OR=2.846, 95%CI: 1.575-5.143), ASPECT score<6 (OR=2.616, 95%CI: 1.168-5.857), and core infarct volume>70 ml (OR=2.712, 95%CI: 1.130-6.505) were risk factors for futile recanalization. Conclusion: Age≥80 years, previous stroke history, baseline NIHSS score≥20, GCS score≤8, general anesthesia, ASPECT score<6, core infarct volume>70 ml, and failure to achieve Grade 3 recanalization are independent influencing factors for futile recanalization after endovascular therapy in AIS-LVO patients.

Drainage, Irrigation, and Fibrinolytic Therapy (DRIFT) for Adult Intraventricular Hemorrhage Associated with Primary Hypertensive Hemorrhages Using IRRAflow Self-Irrigating Catheter: A Report of Three Cases and Prior Historical Controls

Spontaneous primary intracerebral hemorrhage(ICH) accounts for 10-15% of strokes and is accompanied by ventricular involvement in 10-30% of cases. Intraventricular hemorrhage(IVH) is a poor prognostic factor and the current treatment paradigm of external ventricular drainage requires frequent flushing and replacement. Given the documented high rate of failure standard EVD catheters, we sought to determine if the use of the IRRAflow® system with the addition of alteplase would be beneficial in this patient population for the treatment of IVH associated with primary hypertensive ganglionic hemorrhages METHODS: Three patients with ganglionic hemorrhages and IVH underwent treatment with the IRRAflow system at our institution from December 2022 to January 2023. A retrospective review was then performed of patients with primary hypertensive ganglionic hemorrhages and EVD placement at our institution from January 2021 to present day. Three patients underwent treatment with the IRRAflow® system and continuous lavage of tPA. The IVH was efficiently cleared in all cases and the drains were removed within 8 days in all cases. No patients required replacement of the drain and there were no hemorrhagic complications noted. In our retrospective review, 28 patients were identified who underwent placement of a standard EVD for the treatment of primary hypertensive ganglionic hemorrhages. When patients who had early withdrawal of care were excluded, the average length of EVD treatment was 11.3 days and the EVD replacement rate was 24%. We demonstrate here that the use of the IRRAflow system for the treatment of primary hypertensive hemorrhages with IVH results in rapid clearance of the IVH without safety concerns. Compared to historical controls there was a decrease in EVD duration, EVD replacement and ICU LOS.

P-778 Same mother-different Oocyte: Comparison of obstetric and perinatal outcomes between pregnancies achieved through oocyte donation versus those achieved through spontaneous conception for the same mother

Abstract Study question Is there a difference in obstetrical and perinatal outcomes between pregnancies achieved through oocyte donation versus those achieved through spontaneous conception for the same mother Summary answer OD pregnancies show higher incidences of preterm labor and pregnancy-induced hypertension, and lower incidences of small for gestational age, compared to spontaneous pregnancies What is known already Oocyte donation (OD) is an integral part of modern assisted reproductive care and has been used for over three decades. OD pregnancies have an increased rate of hypertension, cesarean section, and preterm labor. Yet most of these complications are attributed to the mothers going through OD, not to the biological effect of different oocyte sources (autologous Vs. donation). Study design, size, duration This study is a retrospective cohort study that utilizes electronic data from Maccabi Healthcare Services. This 2.5-million-patient integrated care organization represents 25% of the pregnant population in the country. The data used in this study were collected from 2000 through 2018. Participants/materials, setting, methods The study included mothers who experienced both a spontaneous conception (SP) pregnancy and later an oocyte donation (OD) pregnancy. The study compared obstetric and perinatal outcomes, including the incidence of preterm labor (PTL) and small for gestational age (SGA). Mother's obstetric outcomes such as pregnancy induced hypertension (PIH), gestational diabetes, malpresentation, and postpartum hemorrhage were also analyzed. A paired t-test was performed to compare each outcome for the same mother Main results and the role of chance The cohort included 194 mothers who had a first spontaneous pregnancy and a second pregnancy with oocyte donation. The mean age of the mother during her OD pregnancy was statistically older than the OD pregnancy (mean difference 2.2 years, p = 0.0028). No difference was found between pregnancies regarding the BMI (p = 0.216). A trend toward a higher prevalence of PIH was found in the OD pregnancy compared to the SP (mean difference 2.5, p = 0.058). No difference was found between pregnancies regarding gestational diabetes (p = 0.7), malpresentation (p = 1), retained placenta (p = 0.318), and Cesarean section (p = 0.565). Perinatal outcomes show a higher prevalence of premature labor before the 34th week and 32nd week in the OD pregnancies compared to SC pregnancies (mean difference 3.6, p = 0.034 and mean difference 3, p = 0.33 respectively). No difference was found between pregnancies regarding labor before the 37th week (p = 1). A statistically lower prevalence of SGA was found in the OD pregnancy compared to the SP (p = 0.0057). Limitations, reasons for caution Due to its retrospective character, some information is lacking. Information regarding indications leading to OD/AO are missing which might have elaborated our findings Wider implications of the findings OD pregnancies should be considered high-risk, primarily due to the increased risk of PTL and PIH. Adequate recommendations should be considered, including cervical length surveillance, frequent blood pressure measurements, and perhaps prophylactic low-dose aspirin to reduce the risk of preeclampsia.

Normotensive state during acute phase of hypertensive intracerebral hemorrhage.

Hypertensive hemorrhage is a leading cause of intracerebral haemorrhage (ICH), although some of these patients may not present with high blood pressure (BP) at the time of ICH. This retrospective study included patients with history of hypertension presenting with ICH. Patients with systolic BP recording of more than 140 mmHg were included in hypertension group (group I). Patients whose BP rose to hypertension range after fluid correction were included in group II and patients with BP <140 mmHg on consecutive 1-week BP recordings were included in group III. Clinical features including volume of ICH of all the three groups were noted. Outcome in the form of mortality was analyzed. Chi-square test was used for categorical variables and independent t-test for continuous variables. P < 0.05 was considered significant. Ninety-two ICH patients with history of hypertension were included in the study. Of them, 20 patients (22%) presented with BP <140 mmHg systolic at the time of ICH. After fluid correction, it rose to hypertensive range in 9 (10%) but remained normal in 11 patients (12%) during consecutive recordings for 1-week post-admission. On comparing normotensive and hypertensive groups, significant difference was seen in survival and volume of ICH. There is a subset of hypertensive patients who may present with normal BP recording during acute ICH. The BP rises subsequently with the correction of hypovolemia in some. The volume of hemorrhage in normotensives is relatively small but whether this translates into better prognosis needs further studies.

Prevalence of Gestational Diabetes and Associated Maternal Factor

The prevalence of gestational diabetes is rising all over the world. Maternal and neonatal complications are associated with gestational diabetes Mellitus. Objective: To investigate the prevalence of gestational diabetes and associated maternal factors in outpatients of Jinnah Hospital Lahore. Methods: The descriptive cross-sectional study design was used to assess the prevalence of gestational diabetes and associated maternal factors with a 200-population size that is deliberated from Slovin’s formula for the pregnant women of the Gynae outpatient’s department at Jinnah Hospital Lahore. The convenient sampling technique is used to collect the data from pregnant women. The study took approximately 9 months. The questionnaire asked about sociodemographic factors, family history, and medical history. Results: The prevalence of gestational diabetes mellitus was 36.8% in Pakistan. Positive family history (41.4%), increased BMI (46.6%), parity (83.5%), and obesity (59.2%) were determinants of gestational diabetes mellitus. Maternal complications like pre-eclampsia (8.3%), pregnancy-induced hypertension (20.1%), cesarean (48.9%), and antepartum hemorrhage (20.2%) were higher in GDM women. Conclusions: The study finding reveals that gestational diabetes mellitus was discovered to be highly prevalent in Pakistani women and they were at higher risk of developing maternal complications. Women with advanced maternal age, low monthly income, obesity, a family history of diabetes, parity number, and increased BMI are risk factors for Gestational diabetes mellitus.

Partial splenic embolization as a rescue and emergency treatment for portal hypertension and gastroesophageal variceal hemorrhage

BackgroundPartial splenic embolization (PSE) is a non-surgical procedure which was initially used to treat hypersplenism. Furthermore, partial splenic embolization can be used for the treatment of different conditions, including gastroesophageal variceal hemorrhage. Here, we evaluated the safety and efficacy of emergency and non-emergency PSE in patients with gastroesophageal variceal hemorrhage and recurrent portal hypertensive gastropathy bleeding due to cirrhotic (CPH) and non-cirrhotic portal hypertension (NCPH).MethodsFrom December 2014 to July 2022, twenty-five patients with persistent esophageal variceal hemorrhage (EVH) and gastric variceal hemorrhage (GVH), recurrent EVH and GVH, controlled EVH with a high risk of recurrent bleeding, controlled GVH with a high risk of rebleeding, and portal hypertensive gastropathy due to CPH and NCPH underwent emergency and non-emergency PSE. PSE for treatment of persistent EVH and GVH was defined as emergency PSE. In all patients pharmacological and endoscopic treatment alone had not been sufficient to control variceal bleeding, and the placement of a transjugular intrahepatic portosystemic shunt (TIPS) was contraindicated, not reasonable due to portal hemodynamics, or TIPS failure with recurrent esophageal bleeding had occurred. The patients were followed-up for six months.ResultsAll twenty-five patients, 12 with CPH and 13 with NCPH were successfully treated with PSE. In 13 out of 25 (52%) patients, PSE was performed under emergency conditions due to persistent EVH and GVH, clearly stopping the bleeding. Follow-up gastroscopy showed a significant regression of esophageal and gastric varices, classified as grade II or lower according to Paquet’s classification after PSE in comparison to grade III to IV before PSE. During the follow-up period, no variceal re-bleeding occurred, neither in patients who were treated under emergency conditions nor in patients with non-emergency PSE. Furthermore, platelet count increased starting from day one after PSE, and after one week, thrombocyte levels had improved significantly. After six months, there was a sustained increase in the thrombocyte count at significantly higher levels. Fever, abdominal pain, and an increase in leucocyte count were transient side effects of the procedure. Severe complications were not observed.ConclusionThis is the first study analyzing the efficacy of emergency and non-emergency PSE for the treatment of gastroesophageal hemorrhage and recurrent portal hypertensive gastropathy bleeding in patients with CPH and NCPH. We show that PSE is a successful rescue therapy for patients in whom pharmacological and endoscopic treatment options fail and the placement of a TIPS is contraindicated. In critically ill CPH and NCPH patients with fulminant gastroesophageal variceal bleeding, PSE showed good results and is therefore an effective tool for the rescue and emergency management of gastroesophageal hemorrhage.
