How old is too old to fight in boxing?

Professional boxing is a popular combat sport worldwide. It is a physically demanding sport, and professional boxers are usually in their mid to late 20’s. At around 35-years of age most boxers begin to show signs of physical decline. Boxers hence begin to retire from professional boxing around 35-years of age. Recently older combatants are entering the ring and cage to ply their trade. These are either former professional combatant who is choosing to come out of retirement or celebrities who are getting pitted against each other in exhibition boxing matches (popularly referred to as celebrity boxing). Many of these “combatants” are on the wrong side of 40, have little to no formal training in combat sports and poor physical conditioning. Boxing and MMA are referred to as combat sports. Neurological, orthopedic, and ophthalmological injuries are common. While some are life threatening others has the potential to cause lifelong disability. Boxers sometimes die in the ring due to acute traumatic subdural hematoma (SDH). Concern is hence raised for the health and wellbeing of these older athletes. Should an athlete above the age of 40 compete in professional boxing? How old is too old to fight in boxing?

124 Craniotomy Versus Craniectomy for Traumatic Acute Subdural Hematoma Coarsened Exact Matched Analysis of Outcomes

INTRODUCTION: Previous studies comparing craniotomy (CO) versus decompressive hemicraniectomy (DC) for acute subdural hematoma (aSDH) evacuation after traumatic brain injury have not found significant association between surgical approach and patient outcome. We hoped to provide a more granular and real-world assessment of outcomes. METHODS: One hundred thirty-eight patients underwent CO (N = 76) or DC (N = 62) for traumatic aSDH. DC patients were on average 21.4 years younger (P < 0.001), more likely to be male (80.6% vs 60.5%, P = 0.011), and present with GCS = 8 (64.5% vs 36.8%, P = 0.001). Age (P < 0.001), EDH (P = 0.01), skull fracture (P = 0.001), and cisternal effacement (P = 0.02) were independently associated with surgical approach. After coarsened exact matching, DC (P = 0.008), older age (P = 0.007), male sex (P = 0.04), and IVH (P = 0.02), were independently associated with inpatient mortality. Multivariate Cox proportional-hazards regression demonstrated that DC was independently associated with mortality at 90-days (P = 0.001) and 1-year post-operation (P = 0.003) for matched patients. RESULTS: One hundred thirty-eight patients underwent CO (N = 76) or DC (N = 62) for traumatic aSDH. DC patients were on average 21.4 years younger (P < 0.001), more likely to be male (80.6% vs 60.5%, P = 0.011), and present with GCS = 8 (64.5% vs 36.8%, P = 0.001). Age (P < 0.001), EDH (P = 0.01), skull fracture (P = 0.001), and cisternal effacement (P = 0.02) were independently associated with surgical approach. After coarsened exact matching, DC (P = 0.008), older age (P = 0.007), male sex (P = 0.04), and IVH (P = 0.02), were independently associated with inpatient mortality. Multivariate Cox proportional-hazards regression demonstrated that DC was independently associated with mortality at 90-days (P = 0.001) and 1-year post-operation (P = 0.003) for matched patients. CONCLUSIONS: aSDH patients who receive surgical evacuation via DC as opposed to CO are younger, more likely to be male, and have worse clinical exam. After controlling for patient differences via coarsened exact matching, DC is an independent predictor of mortality at discharge, as well as at 90-days and 1-year after surgery.

Simulating Cerebral Edema and Ischemia After Traumatic Acute Subdural Hematoma Using Triphasic Swelling Biomechanics.

Poor outcome following traumatic acute subdural hematoma (ASDH) is associated with the severity of the primary injury and secondary injury including cerebral edema and ischemia. However, the underlying secondary injury mechanism contributing to elevated intracranial pressure (ICP) and high mortality rate remains unclear. Cerebral edema occurs in response to the exposure of the intracellular fixed charge density (FCD) after cell death, causing ICP to increase. The increased ICP from swollen tissue compresses blood vessels in adjacent tissue, restricting blood flow and leading to ischemic damage. We hypothesize that the mass occupying effect of ASDH exacerbates the ischemic injury, leading to ICP elevation, which is an indicator of high mortality rate in the clinic. Using FEBio (febio.org) and triphasic swelling biomechanics, this study modeled clinically relevant ASDHs and simulated post-traumatic brain swelling and ischemia to predict ICP. Results showed that common convexity ASDH significantly increased ICP by exacerbating ischemic injury, and surgical removal of the convexity ASDH may control ICP by preventing ischemia progression. However, in cases where the primary injury is very severe, surgical intervention alone may not effectively decrease ICP, as the contribution of the hematoma to the elevated ICP is insignificant. In addition, interhemispheric ASDH, located between the cerebral hemispheres, does not significantly exacerbate ischemia, supporting the conservative surgical management generally recommended for interhemispheric ASDH. The joint effect of the mass occupying effect of the blood clot and resulting ischemia contributes to elevated ICP which may increase mortality. Our novel approach may improve the fidelity of predicting patient outcome after motor vehicle crashes and traumatic brain injuries due to other causes.

Perfusion tomography in early follow-up of acute traumatic subdural hematoma: a case series.

Perfusion Computed Tomography (PCT) is an alternative tool to assess cerebral hemodynamics during trauma. As acute traumatic subdural hematomas (ASH) is a severe primary injury associated with poor outcomes, the aim of this study was to evaluate the cerebral hemodynamics in this context. Five adult patients with moderate and severe traumatic brain injury (TBI) and ASH were included. All individuals were indicated for surgical evacuation. Before and after surgery, PCT was performed and cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were evaluated. These parameters were associated with the outcome at 6 months post-trauma with the extended Glasgow Outcome Scale (GOSE). Mean age of population was 46 years (SD: 8.1). Mean post-resuscitation Glasgow coma scale (GCS) was 10 (SD: 3.4). Mean preoperative midline brain shift was 10.1mm (SD: 1.8). Preoperative CBF and MTT were 23.9ml/100g/min (SD: 6.1) and 7.3s (1.3) respectively. After surgery, CBF increase to 30.7ml/100g/min (SD: 5.1), and MTT decrease to 5.8s (SD:1.0), however, both changes don't achieve statistically significance (p = 0.06). Additionally, CBV increase after surgery, from 2.34 (SD: 0.67) to 2.63ml/100g (SD: 1.10), (p = 0.31). Spearman correlation test of postoperative and preoperative CBF ratio with outcome at 6 months was 0.94 (p = 0.054). One patient died with the highest preoperative MTT (9.97s) and CBV (4.51ml/100g). CBF seems to increase after surgery, especially when evaluated together with the MTT values. It is suggested that the improvement in postoperative brain hemodynamics correlates to favorable outcome.

Decompressive Craniectomy versus Craniotomy for Acute Subdural Hematoma: Updated meta-analysis of real-world clinical outcome after RESCUE-ASDH trial.

The RESCUE-ASDH trial found that disability and quality-of-life outcomes were similar between craniotomy and decompressive craniectomy for traumatic acute subdural hematoma, contrasting previous literature. This meta-analysis aims to validate the applicability of RESCUE-ASDH results using real-world data in acute subdural hematoma patients. We searched Chocrane, Embase, and MEDLINE for relevant articles reporting clinical outcomes of craniotomy and decompressive craniectomy. Meta-analysis utilized R software with the restricted maximum likelihood method for random-effects meta-analyses, presenting odds ratios and 95% confidence intervals with Hartung-Knapp-Sidik-Jonkman adjustment for heterogeneity. Besides RESCUE-ASDH, 5 retrospective studies were included, spanning 2006-2016. A total of 961 patients with traumatic ASDH were included in this study (Craniotomy = 467; Decompressive craniotomy = 494). The pooled analysis of retrospective studies showed no significant difference in poor clinical outcomes between the two groups (OR 0.59, 95% CI, 0.32 to 1.10). These findings align with the RESCUE-ASDH trial (OR 0.84, 95% CI, 0.58 to 1.23). Mortality rate was significant higher in patients undergoing craniectomy in pooled result of retrospective studies (OR 0.59, 95% CI, 0.32 to 1.10). In RESCUE-ASDH trial, reoperation rate was higher in the craniotomy group, but the pooled result of retrospective did not show significant difference between the craniotomy and craniectomy group. This real-world evidence confirms the RESCUE-ASDH trial results. Both craniotomy and decompressive craniectomy yielded similar disability and quality-of-life outcomes for traumatic acute subdural hematoma patients. Level 2, Systematic and meta-analysis.

Incidence, risk factors, and clinical outcomes of acute brain swelling associated with traumatic acute subdural hematoma: a retrospective study utilizing novel diagnostic criteria.

Post-traumatic acute brain swelling (ABS) is a major cause of elevated intracranial pressure and thus mortality. The current definition of post-traumatic ABS has certain limitations, and there is limited information available regarding ABS associated with traumatic acute subdural hematoma (ASDH). To investigate the incidence, risk factors, and clinical outcomes of ABS associated with traumatic ASDH. Retrospective study. Data for 161 patients diagnosed with traumatic ASDH were retrospectively collected. Novel computed tomography-based criteria were proposed for diagnosing ABS in patients with ASDH and determining its incidence. Univariate and multivariate logistic regression analyses were performed to explore the risk factors of post-traumatic ABS. The Glasgow Outcome Scale (GOS) score, mortality, and functional prognosis of all patients at discharge and the proportion of intraoperative malignant brain bulge in surgical patients were taken as clinical outcome measures. A total of 45 (28%) patients experienced post-traumatic ABS, exhibiting significantly lower Glasgow Coma Scale scores on admission (p < 0.001). The incidence of hemispheric and whole-brain swelling was 8.1% and 19.9%, respectively. Risk factors independently associated with post-traumatic ABS were: (1) age [odds ratio (OR) = 0.917, p < 0.001]; (2) platelet to white blood cell ratio (PWR) (OR = 0.887, p = 0.012); and (3) traumatic subarachnoid hemorrhage (SAH) (OR = 4.346, p = 0.005). The ABS cohort had a lower GOS score [2 (1-3) versus 4 (3-5); p < 0.001], higher mortality (46.7% versus 6.9%; p < 0.001), and higher proportion of unfavorable functional prognosis (75.6% versus 34.5%; p < 0.001) upon discharge compared to the no ABS cohort, along with higher proportion of intraoperative malignant brain bulge (43.8% versus 0%; p < 0.001). The incidence of ABS associated with ASDH is significantly high overall. Patients with ASDH who have young age, low PWR, and traumatic SAH are at an increased risk of developing post-traumatic ABS, and therefore of poor clinical outcomes.

Deadliness of Traumatic Subdural Hematomas in the First Quarter of the Year: A Measurement by the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP).

Background Traumatic acute subdural hematoma (ASDH) is a surgical emergency and has been associated with high morbidity and mortality. However, it is not known whether mortality from ASDH occurs more frequently in a particular season. Methodology We queried the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) from 2016 to 2019. They were identified in the NSQIP using the International Classification of Diseases (ICD-10) code S06.5 to capture all admissions with a primary diagnosis of traumatic subdural hematoma. Mortality rates were reviewed per season, defined as three consecutive months in the year. Demographics such as age, race, ethnicity, height, and weight were reviewed. Comorbidities such as diabetes, risk factors, including smoking history, and hospitalization characteristics, such as admission year, operation year, and inpatient/outpatient treatment type, were also reviewed. Results A total of 1,656 patients were included in this study. The mean age of all participants was 70.6 years, with 37% (604/1,656) being female. The mortality rate was highest in January, February, and March at 24.5% (104/425, P= 0.045) of admitted patients compared to mortality rates of 18.8% (70/373) in April to June, 18.4% (81/441) in July to September, and 17.5% (73/417) in October to December. Conclusions Mortality is significantly greater during the winter months of January, February, and March among patients with ASDH. Despite better survival rates of ASDH over the past two decades, postoperative mortality rates still remain high.

Comparison of the decompressive craniectomy results in patients with ischemic stroke and acute subdural hematoma and determination of prognostic markers

Aims: This study aimed to investigate the therapeutic effectiveness of decompressive craniectomy in patients with traumatic acute subdural hematoma and stroke patients and to determine the parameters that could predict the risk of mortality in these patients. Methods: Patients diagnosed and operated on with acute subdural hematoma (ASH) or stroke between January 2022 and September 2023 were grouped into the ASH group and the CVO group. The patients were also divided into DEAD and SURVIVED groups according to mortality. Age, gender, anisocoria, the area of the craniectomy field, length of stay in the intensive care unit (ICU), length of stay in the hospital, and Glasgow Outcome Scale scores were recorded. In addition, Glasgow Coma Scale (GCS) scores, the amount of midline shift, and the blood biochemistry results were recorded pre-and postoperatively. Results: This study consisted of 11 (5 male and 6 female) patients. Sex, preoperative GCS score, anisocoria, postoperative sedation anesthesia time, postoperative GCS score, duration of stay in the ICU, preoperative serum blood urine nitrogen, preoperative serum C-reactive protein (CRP), postoperative neutrophil-to-lymphocyte ratio, and postoperative CRP values were different between the ASH and CVO groups (p&lt;0.05). Furthermore, the preoperative GCS score, postoperative GCS score, postoperative sedation anesthesia duration, postoperative serum aspartate aminotransferase (AST), and postoperative serum CRP level values were different between the DEAD and SURVIVED groups (p&lt;0.05). The correlation analysis results revealed a positive correlation between mortality and preoperative GCS score and a negative correlation between mortality and anisocoria (p&lt;0.05). The ROC-curve analysis revealed that preoperative GCS and postoperative GCS score, postoperative midline shift, postoperative serum AST level value, and postoperative serum CRP level value could predict mortality risk (p&lt;0.05). However, Logistic Regression analysis showed that any study parameter could be used as the best marker for prediction of the postoperative mortality risk (p&gt;0.05). Conclusion: This study showed that decompressive craniectomy may offer more satisfactory results in severe head trauma patients. It was also argued that preoperative and postoperative GCS scores, postoperative midline shift values, and postoperative serum AST and CRP level values could be used to predict mortality risk.

Impact of Antithrombotic Medications and Reversal Strategies on the Surgical Management and Outcomes of Traumatic Acute Subdural Hematoma

Careful hematologic management is required in surgical patients with traumatic acute subdural hematoma (aSDH) taking antithrombotic medications. We sought to compare outcomes between patients with aSDH taking antithrombotic medications at admission who received antithrombotic reversal with patients with aSDH not taking antithrombotics. Retrospective review identified patients with traumatic aSDH requiring surgical evacuation. The cohort was divided based on antithrombotic use and whether pharmacologic reversal agents or platelet transfusions were administered. A 3-way comparison of outcomes was performed between patients taking anticoagulants who received pharmacologic reversal, patients taking antiplatelets who received platelet transfusion, and patients not taking antithrombotics. Multivariable regressions, adjusted for injury severity, further investigated associations with outcomes. Of 138 patients who met inclusion criteria, 13.0% (n= 18) reported taking anticoagulants, 16.7% (n= 23) reported taking antiplatelets, and 3.6% (n= 5) reported taking both. Patients taking antiplatelets who received platelet transfusion had longer intraoperative times (P= 0.040) and higher rates of palliative care consultations (P= 0.046) compared with patients taking anticoagulants who received pharmacologic reversal and patients not taking antithrombotics. Across groups, no significant differences were found in frequency of in-hospital intracranial hemorrhage and venous thromboembolism, length of hospital stay, rate of inpatient mortality, or follow-up health status. In multivariable analysis, intraoperative time remained longest for the antiplatelets with platelet transfusion group. Other outcomes were not associated with patient group. Among surgical patients with traumatic aSDH, those taking antiplatelet medications who receive platelet transfusions experience longer intraoperative procedure times and higher rates of palliative care consultation. Comparable outcomes were observed between patients receiving antithrombotic reversal and patients not taking antithrombotics.

Craniotomy versus craniectomy for traumatic acute subdural hematoma—coarsened exact matched analysis of outcomes

Background and objectivesAcute subdural hematoma (aSDH) after traumatic brain injury frequently requires emergent craniotomy (CO) or decompressive craniectomy (DC). We sought to determine the variables associated with either surgical approach and to compare outcomes between matched patients. MethodsA multi-center retrospective review was used to identify traumatic aSDH patients who underwent CO or DC. Patient variables independently associated with surgical approach were used for coarsened exact matching.Multivariate logistic regression and multivariate Cox proportional-hazards regression wereconducted on matched patients to determine independent predictors of mortality. ResultsSeventy-six patients underwent CO and sixty-two underwent DC for aSDH evacuation. DC patients were21.4 years younger (P < 0.001), more likely to be male (80.6 % vs 60.5 %,P = 0.011), and present with GCS ≤ 8 (64.5 % vs 36.8 %,P = 0.001). Age (P < 0.001), epidural hematoma (P = 0.01), skull fracture (P = 0.001), and cisternal effacement (P = 0.02) were independently associated with surgical approach. After coarsened exact matching, DC (P = 0.008), older age (P = 0.007), male sex (P = 0.04), and intraventricular hemorrhage (P = 0.02), were independently associated with inpatient mortality. Multivariate Cox proportional-hazards regression demonstrated that DC was independently associated with mortality at 90-days (P = 0.001) and 1-year post-operation (P = 0.003). ConclusionaSDH patients who receive surgical evacuation via DC as opposed to CO are younger, more likely to be male, and have worse clinical exam. After controlling for patient differences via coarsened exact matching, DC is independently associated with mortality.

Retrospective Observational Study of Patients With Subdural Hematoma Treated With Idarucizumab.

Use of anticoagulants is increasing with the aging of societies. The safe first-line drug is likely to be a direct oral anticoagulant (DOAC), but outcomes of treatment of traumatic brain injury (TBI) with anticoagulants are uncertain. Therefore, we examined the clinical effect of idarucizumab as reversal therapy in elderly patients with TBI who were treated with dabigatran. A retrospective multi-center observational study was performed in patients ≥65 years of age who developed acute traumatic subdural hematoma during treatment with dabigatran and underwent reversal therapy with idarucizumab. The items examined included patient background, neurological and imaging findings at arrival, course after admission, complications, and outcomes. A total of 23 patients were enrolled in the study. The patients had a mean age of 78.9 years. Cause of TBI was fall in 60.9% of the subjects. Mean Glasgow Coma Scale score at arrival was 8.7; anisocoria was present in 31.8% of cases. Exacerbation of consciousness was found in 30.4%, but only in 13.3% of subjects treated with idarucizumab before consciousness and imaging findings worsened. Dabigatran was discontinued in 81.8% of cases after hematoma development, with a mean withdrawal period of 12.1 days. The favorable outcome rate was 21.7%, and mortality was 39.1%. In multi-variate analysis, timing of idarucizumab administration was associated with a favorable outcome. There were ischemic complications in 3 cases (13.1%), and all three events occurred ≥7 days after administration of idarucizumab. These findings suggest that in cases that develop hematoma during treatment with dabigatran, it is important to administer idarucizumab early and restart dabigatran after conditions stabilize.

Factors Predicting Outcome of Surgically Treated Acute Subdural Hematoma

Objective: The study aimed to evaluate operative mortality and prognosis factors in posttraumatic acute subdural hematoma patients. Material &amp; Methods: A prospective cross-sectional study was done in the Department of Neurosurgery, Ayub Teaching Hospital Abbottabad. 82 patients operated for Acute Subdural Hematoma were included in the study. Variables that influence the outcome were recorded. The outcome was measured in terms of mortality. Results: Of 82 patients operated on, 61 were male, and 21 were female. 51 were &lt;40 old years, 21 were aged 41-60, and 7 were over 60. The most common cause is fall from height (47.6%). Cerebral contusion is often associated (28%). Overall mortality: 39.2%. Male mortality: 29.2%, female: 9.7%. Surgery &gt;4 hours post-injury had higher mortality (18.2%) vs. &lt;4 hours (8.5%). 14/43 GCS &lt;8 patients survived, with no deaths when GCS &gt;12. Pupillary abnormalities had higher mortality (31.9%) vs. normal pupils (7.3%). No deaths with hematoma thickness &lt;10mm and only 1 survived with a thickness &gt;16mm. 25/29 died with midline shift &gt;11mm. Conclusion: Prognostic factors for surgically treated traumatic acute subdural hematoma include GCS at presentation, pupils, hematoma thickness, midline shift, and time to surgery. Better outcomes associated with GCS&gt;9, normal pupils, hematoma width &lt;1.5cm, midline shift &lt;1cm, and surgery within 4 hours.

Outcomes After the Surgical Evacuation of Traumatic Acute Subdural Hematomas: The tASDH Risk Score

Acute subdural hematoma (ASDH) is a common pathology following traumatic brain injury (TBI). There is sparse data on the prediction of clinical outcomes following traumatic ASDH (tASDH) evacuation. We investigated prognosticators of outcome following evacuation of tASDHs, with subset analysis in a cohort of octogenarians. We developed a scoring system for stratifying the risk of in-hospital mortality for patients undergoing tASDH evacuation. A retrospective chart review was performed to identify all patients who underwent tASDH evacuation. Baseline clinical and demographic data including age, traumatic brain injury mechanism, admission Glasgow Coma Scale (GCS), and Rotterdam computed tomography Scale (RCS) were collected. In-hospital outcomes such as mortality and discharge disposition were collected. A scoring system (tASDH Score) which incorporates RCS (1-2 points), admissions GCS (0-1 points), and age (0-1 point) was created to predict the risk of in-hospital mortality following tASDH evacuation. Being an octogenarian (OR=6.91 [2.20-21.71], P= 0.0009), having a GCS of 9-12 (OR=1.58 [1.32-4.12], P= 0.027) or 3-8 (OR=2.07 [1.41-10.38], P= 0.018), and having an RCS of 4-6 (OR=3.49 [1.45-8.44], P= 0.0055) were independently predictive of in-hospital mortality. The in-hospital mortality rate was lower for those with a tASDH score of 1 (10%), compared to those with a score of 2 (12%), 3 (42%), and 4 (100%). Octogenarians with an RCS of 4-6 and an admission GCS <13 have a high risk of mortality following tASDH evacuation. Knowledge of which patients are unlikely to survive ASDH evacuation may help guide neurosurgeons in prognostication and goals of care discussions.

Comparative effectiveness of decompressive craniectomy versus craniotomy for traumatic acute subdural hematoma (CENTER-TBI): an observational cohort study

Limited evidence existed on the comparative effectiveness of decompressive craniectomy (DC) versus craniotomy for evacuation of traumatic acute subdural hematoma (ASDH) until the recently published randomised clinical trial RESCUE-ASDH. In this study, that ran concurrently, we aimed to determine current practice patterns and compare outcomes of primary DC versus craniotomy. We conducted an analysis of centre treatment preference within the prospective, multicentre, observational Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (known as CENTER-TBI) and NeuroTraumatology Quality Registry (known as Net-QuRe) studies, which enrolled patients throughout Europe and Israel (2014-2020). We included patients with an ASDH who underwent acute neurosurgical evacuation. Patients with severe pre-existing neurological disorders were excluded. In an instrumental variable analysis, we compared outcomes between centres according to treatment preference, measured by the case-mix adjusted proportion DC per centre. The primary outcome was functional outcome rated by the 6-months Glasgow Outcome Scale Extended, estimated with ordinal regression as a common odds ratio (OR), adjusted for prespecified confounders. Variation in centre preference was quantified with the median odds ratio (MOR). CENTER-TBI is registered with ClinicalTrials.gov, number NCT02210221, and the Resource Identification Portal (Research Resource Identifier SCR_015582). Between December 19, 2014 and December 17, 2017, 4559 patients with traumatic brain injury were enrolled in CENTER-TBI of whom 336 (7%) underwent acute surgery for ASDH evacuation; 91 (27%) underwent DC and 245 (63%) craniotomy. The proportion primary DC within total acute surgery cases ranged from 6 to 67% with an interquartile range (IQR) of 12-26% among 46 centres; the odds of receiving a DC for prognostically similar patients in one centre versus another randomly selected centre were trebled (adjusted median odds ratio 2.7, p<0.0001). Higher centre preference for DC over craniotomy was not associated with better functional outcome (adjusted common odds ratio (OR) per 14% [IQR increase] more DC in a centre=0.9 [95% CI 0.7-1.1], n=200). Primary DC was associated with more follow-on surgeries and complications [secondary cranial surgery 27% vs. 18%; shunts 11 vs. 5%]; and similar odds of in-hospital mortality (adjusted OR per 14% IQR more primary DC 1.3 [95% CI (1.0-3.4), n=200]). We found substantial practice variation in the employment of DC over craniotomy for ASDH. This variation in treatment strategy did not result in different functional outcome. These findings suggest that primary DC should be restricted to salvageable patients in whom immediate replacement of the bone flap is not possible due to intraoperative brain swelling.

Results of treatment of patients with an acute small traumatic subdural hematoma

Patients with small acute traumatic subdural hematomas in the compensated clinical condition can be managed conservatively and have a favorable outcome. We have analyzed our own experience of conservative management of 94 patients with small acute traumatic subdural hematomas. In 16 patients (17 %), hematoma expansion occurred in the next 2–7 days and surgical treatment was required. Significant factors of hematoma expansion are its initial maximum thickness of 8–9 mm and arterial hypertension during the observation period in the hospital. There were no lethal cases in the group of patients who required delayed surgical treatment. Clinical outcomes, both in the conservative group and in the group requiring delayed surgery, did not differ significantly; all patients were discharged with 4–5 points on the Glasgow Outcome Scale. Thus, conservative management of patients with small acute subdural hematomas is safe even in case of hematoma expansion with timely surgical intervention

Outcomes in Children with Shaken Baby Syndrome and Seizures (P14-9.009)

<h3>Objective:</h3> The present study aims to elucidate the factors contributing to poor outcomes in patients with acute seizures following Shaken Baby Syndrome (SBS). <h3>Background:</h3> SBS is the most common cause of severe neurological injury resulting from child abuse and is associated with subdural and retinal hemorrhages. Seizures are a common yet underdiagnosed feature of this syndrome and are associated with poor outcomes. <h3>Design/Methods:</h3> We retrospectively identified patients with SBS and seizures who were diagnosed between 2015–2020. Detailed chart review was performed under IRB-approved study criteria. Demographic, clinical, imaging, lab, and neurophysiology studies information was systematically collected. Logistic regression analysis was used to evaluate factors contributing to poor outcomes. <h3>Results:</h3> A total of 23 patients with acute seizures following SBS were included. The mean age was 7 months (range 3 weeks - 4 years). Six(26%) patients had a presenting GCS of 7 or less, while status epilepticus presented in 7(30%) patients. All included patients had acute traumatic subdural hematoma, retinal hemorrhage, and seizures in the acute period. Overall mortality was 2(9%). Logistic regression analysis identified craniotomy (p:0.01, OR:215.00; 95% CI 3.45–13408.47), SDH thickness &gt;1 cm (p:0.02, OR:68.33; 95% CI 2.15–2173.12), midline shift &gt;1 mm (p:0.03, OR:39.00; 95% CI 1.42–1067.60), and age &gt;24 months (p:0.01, OR:215.00; 95% CI 3.45–13408.47) as predictors of mortality in both univariate and multivariate analysis. Of note, 19(83%) patients had an elevated serum glucose on presentation. <h3>Conclusions:</h3> Seizures in Shaken Baby Syndrome are associated with acute traumatic subdural hematoma, and about 1 in 3 children will develop status epilepticus. Patients with craniotomy to evacuate SDH, SDH thickness &gt;1 cm, midline shift &gt;1 mm, and older age at the time of injury have a worse prognosis. <b>Disclosure:</b> Miss Stebbins has nothing to disclose.

Outcomes In Patients with Traumatic Acute Subdural Hematoma with Non-Convulsive Status Epilepticus (N3.002)

<h3>Objective:</h3> To evaluate the factors contributing to poor outcomes in patients with acute traumatic subdural hematoma (aSDH) who developed nonconvulsive status epilepticus (NCSE). <h3>Background:</h3> NCSE in patients with aSDH is an underdiagnosed yet fatal complication that requires prompt diagnosis and treatment. A high degree of clinical suspicion and evaluation with continuous EEG is required for prompt diagnosis and treatment. <h3>Design/Methods:</h3> This is a single-institution retrospective study approved by the local IRB. Patients with traumatic brain injury (TBI) with aSDH diagnosed with status epilepticus between the years 2016–2020 were included. Demographic, clinical, imaging, treatment, and EEG details were reviewed and collected in a HIPPA-compliant format. Logistic regression analysis was used to evaluate factors contributing to poor outcomes. <h3>Results:</h3> Out of a total of 540 patients, who had presented with traumatic acute intra-cerebral hemorrhage between the years 2016–2022, 28 patients with traumatic aSDH who had presented with status epileptics during the same hospitalization were included in the present study. NCSE was the most common form of status epilepticus (27/28). The mean age was 67 (range 20–92) years and 17(60%) were male. 12(48%) of the patients had an initial presenting GCS of 7 or less. The mean length of stay in the hospital was 16 (5–44) days. Overall mortality was 19(64%). Logistic regression analysis identified the presence of central spikes on EEG (p:0.43, OR:12.72; 95% CI 1.083–149.35) and thickness of aSDH&gt; 1cm (p: 0.025; OR: 16.545; 95%CI: 1.426–191.95) as predictors of mortality in both univariate and multivariate analysis. Good functional outcomes with mRS&lt;2 were seen in rarely 10(35%) of these patients. <h3>Conclusions:</h3> Nonconvulsive status epilepticus (NCSE) is a common form of presentation of status epilepticus in patients with acute traumatic SDH. The presence of epileptiform activity in the central leads in EEG often leads to resistant seizures. NCSE carries a poor prognosis with high mortality. <b>Disclosure:</b> Dr. Mohammed has nothing to disclose. Miss Stebbins has nothing to disclose.

Decompressive Craniectomy versus Craniotomy for Acute Subdural Hematoma

BackgroundTraumatic acute subdural hematomas frequently warrant surgical evacuation by means of a craniotomy (bone flap replaced) or decompressive craniectomy (bone flap not replaced). Craniectomy may prevent intracranial hypertension, but whether it is associated with better outcomes is unclear.MethodsWe conducted a trial in which patients undergoing surgery for traumatic acute subdural hematoma were randomly assigned to undergo craniotomy or decompressive craniectomy. An inclusion criterion was a bone flap with an anteroposterior diameter of 11 cm or more. The primary outcome was the rating on the Extended Glasgow Outcome Scale (GOSE) (an 8-point scale, ranging from death to “upper good recovery” [no injury-related problems]) at 12 months. Secondary outcomes included the GOSE rating at 6 months and quality of life as assessed by the EuroQol Group 5-Dimension 5-Level questionnaire (EQ-5D-5L).ResultsA total of 228 patients were assigned to the craniotomy group and 222 to the decompressive craniectomy group. The median diameter of the bone flap was 13 cm (interquartile range, 12 to 14) in both groups. The common odds ratio for the differences across GOSE ratings at 12 months was 0.85 (95% confidence interval, 0.60 to 1.18; P=0.32). Results were similar at 6 months. At 12 months, death had occurred in 30.2% of the patients in the craniotomy group and in 32.2% of those in the craniectomy group; a vegetative state occurred in 2.3% and 2.8%, respectively, and a lower or upper good recovery occurred in 25.6% and 19.9%. EQ-5D-5L scores were similar in the two groups at 12 months. Additional cranial surgery within 2 weeks after randomization was performed in 14.6% of the craniotomy group and in 6.9% of the craniectomy group. Wound complications occurred in 3.9% of the craniotomy group and in 12.2% of the craniectomy group.ConclusionsAmong patients with traumatic acute subdural hematoma who underwent craniotomy or decompressive craniectomy, disability and quality-of-life outcomes were similar with the two approaches. Additional surgery was performed in a higher proportion of the craniotomy group, but more wound complications occurred in the craniectomy group.

Clinical Diagnosis and Management of Traumatic Acute Intracranial Subdural Hematoma: Review Article

Traumatic brain injury (TBI) is the leading cause of death and disabling conditions in persons. The frequency and severity of head injuries have both decreased as a result of numerous industrial safety improvements, the installation of airbags in automobiles, and the enforcement of speed restrictions. TBI survivorship has increased due to advancements in emergency response times and acute care, but this has also increased the need for accurate ways to detect individuals at risk of subsequent diseases. Pupil reactivity, the Glasgow Coma Scale, and head computed tomography are currently the main clinical signs indicating the existence of brain damage. The current review will cover the clinical presentation, diagnosis, and treatment of TBI,
