The importance of additional intracranial injuries in epidural hematomas: detailed clinical analysis, long-term outcome, and literature review in surgically managed epidural hematomas. Front Surg 2023; 10:1188861. [PMID: 37592941 PMCID: PMC10427765 DOI: 10.3389/fsurg.2023.1188861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 07/03/2023] [Indexed: 08/19/2023] Open
Abstract
Objective Epidural hematomas (EDH) occur in up to 8.2% of all traumatic brain injury patients, with more than half needing surgical treatment. In most patients suffering from this perilous disease, good recovery with an excellent clinical course is possible. However, the clinical course is mainly dependent on the presence of additional intracerebral injuries. Few studies comparing isolated and combined EDH in detail exist. Methods We performed a retrospective single-center study from April 2002 to December 2014. The mean follow-up time was more than 6 years. In addition to analyzing diverse clinicoradiological data, we performed a systematic literature review dealing with a detailed comparison of patients with (combined) and without (isolated) additional intracerebral injuries. Results We included 72 patients in the study. With increasing age, combined EDH had a higher incidence than isolated EDH. The mortality rate of the patients in the cohort was 10%, of which 0% had isolated EDH and 10% had combined EDH. Good recovery was achieved in 69% of patients, of which 91% had isolated EDH and 50% had combined EDH. A subgroup analysis of the different additional intracerebral injuries in combined EDH demonstrated no significant difference in outcome. A systematic literature review only identified six studies. Patients with isolated EDH had a statistically significantly lower mortality risk [relative risk (RR): 0.22; 95% CI: 0.12-0.39] and a statistically significantly lower risk of unfavorable Glasgow outcome scale score (RR: 0.21; 95% CI: 0.14-0.31) than patients with combined EDH. Conclusions An excellent outcome in patients with surgically treated isolated EDH is possible. Furthermore, patients with combined EDH or isolated EDH with a low Glasgow coma scale (GCS) score may have favorable outcomes in 50% of the cases. Therefore, every possible effort for treatment should be made for this potentially lethal injury.

Abstract
Traumatic acute subdural hematomas (ASDH) are common in elderly patients (age ≥65 years) and are associated with a poorer prognosis compared with younger populations. Antithrombotic agent (ATA) use is also common in the elderly; however, the influence that pre-morbid ATA has on outcome in ASDH is poorly understood. We hypothesized that pre-morbid ATA use significantly worsens outcomes in elderly patients presenting with traumatic ASDH. English language medical literature was searched for articles relating to ATA use in the elderly with ASDH. Data were collated and appraised where possible. Analyses of study bias were performed. Twelve articles encompassing 2038 patients were included; controls were poorly described in the included studies. Pre-morbid ATA use was seen in 1042 (51.1%) patients and 18 different ATA combination therapies were identified, with coumarins being the most common single agent used. The newer direct oral anticoagulants were evaluated in only two studies. ATA use was associated with a lower presenting Glasgow Coma Scale (GCS) score but not hematoma volume on computed tomography (CT) or post-operative hematoma re-accumulation. No studies connected ATA use with patient outcomes without the presence of confounders and bias. Reversal strategies, bridging therapy, recommencement of ATA, and comparison groups were poorly described; accordingly, our hypothesis was rejected. ATA reversal methods, identification of surgical candidates, optimal surgery methods, and when or whether ATA should be recommenced following ASDH resolution remain topics of debate. This study defines our current understanding on this topic, revealing clear deficiencies in the literature with recommendations for future research.

Abstract
Objective Subdural hematomas (SDH) account for an estimated 5 to 25% of intracranial hemorrhages. Acute SDH occur secondary to rupture of the bridging veins leading to blood collecting within the dural space. Risk factors associated with SDH expansion are well documented, however, there are no established guidelines regarding blood pressure goals in the management of acute SDH. This study aims to retrospectively evaluate if uncontrolled blood pressure within the first 24 h of hospitalization in patients with acute SDH is linked to hematoma expansion as determined by serial CT imaging. Methods A single center, retrospective study looked at 1,083 patients with acute SDH, predominantly above age 65. Of these, 469 patients met the inclusion criteria. Blood pressure was measured during the first 24 h of admission along with PT, INR, platelets, blood alcohol level, anticoagulation use and antiplatelet use. Follow-up CT performed within the first 24 h was compared to the initial CT to determine the presence of hematoma expansion. Mean systolic blood pressure (SBP), peak SBP, discharge disposition, length of stay and in hospital mortality were evaluated. Results We found that patients with mean SBP <140 in the first 24 h of admission had a lower rate of hematoma expansion than those with SBP > 140. Patients with peak SBP > 200 had an increased frequency of hematoma expansion with the largest effect seen in patients with SBP > 220. Other risk factors did not contribute to hematoma expansion. Conclusions These results suggest that blood pressure is an important factor to consider when treating patients with SDH with medical management. Blood pressure management should be considered in addition to serial neurological exams, repeat radiological imaging, seizure prophylaxis and reversal of anticoagulation.

Abstract
BACKGROUND Traumatic acute subdural hematomas (aSDHs) are common, life-threatening injuries often requiring emergency surgery. OBJECTIVE To develop and validate the Richmond acute subdural hematoma (RASH) score to stratify patients by risk of mortality after aSDH evacuation. METHODS The 2016 National Trauma Data Bank (NTDB) was queried to identify adult patients with traumatic aSDHs who underwent craniectomy or craniotomy within 4 h of arrival to an emergency department. Multivariate logistic regression modeling identified risk factors independently associated with mortality. The RASH score was developed based on a factor's strength and level of association with mortality. The model was validated using the 2017 NTDB and the area under the receiver operating characteristic curve (AUC). RESULTS A total of 2516 cases met study criteria. The patients were 69.3% male with a mean age of 55.7 yr and overall mortality rate of 36.4%. Factors associated with mortality included age between 61 and 79 yr (odds ratio [OR] = 2.3, P < .001), age ≥80 yr (OR = 6.3, P < .001), loss of consciousness (OR = 2.3, P < .001), Glasgow Coma Scale score of ≤8 (OR = 2.6, P < .001), unilateral (OR = 2.8, P < .001) or bilateral (OR = 3.9, P < .001) unresponsive pupils, and midline shift >5 mm (OR = 1.7, P < .001). Using these risk factors, the RASH score predicted progressively increasing mortality ranging from 0% to 94% for scores of 0 to 8, respectively (AUC = 0.72). Application of the RASH score to 3091 cases from 2017 resulted in similar accuracy (AUC = 0.74). CONCLUSION The RASH score is a simple and validated grading scale that uses easily accessible preoperative factors to predict estimated mortality rates in patients with traumatic aSDHs who undergo surgical evacuation.

Abstract
BACKGROUND Antithrombotic-associated subdural hematomas (SDHs) are increasingly common, and the possibility of clinical deterioration in otherwise stable antithrombotic-associated SDH patients may prompt unnecessary admissions to intensive care units. It is unknown whether all antithrombotic regimens are equally associated with the need for critical care interventions. We sought to compare the frequency of critical care interventions and poor functional outcomes among three cohorts of noncomatose SDH patients: patients on no antithrombotics, patients on anticoagulants, and patients on antiplatelets alone. METHODS We performed a retrospective cohort study on all noncomatose SDH patients (Glasgow Coma Scale > 12) presenting to an academic health system in 2018. The three groups of patients were compared in terms of clinical course and functional outcome. Multivariable logistic regression was used to determine predictors of need for critical care interventions and poor functional outcome at hospital discharge. RESULTS There were 281 eligible patients presenting with SDHs in 2018, with 126 (45%) patients on no antithrombotics, 106 (38%) patients on antiplatelet medications alone, and 49 (17%) patients on anticoagulants. Significant predictors of critical care interventions were coagulopathy (OR 5.1, P < 0.001), presence of contusions (OR 3, P = 0.007), midline shift (OR 3.4, P = 0.002), and maximum SDH thickness (OR 2.4, P = 0.002). Significant predictors of poor functional outcome were age (OR 1.8, P < 0.001), admission Glasgow Coma Scale score (OR 0.3, P < 0.001), dementia history (OR 4.2, P = 0.001), and coagulopathy (OR 3.5, P = 0.02). Isolated antiplatelet use was not associated with either critical care interventions or functional outcome. CONCLUSION Isolated antiplatelet use is not a significant predictor of need for critical care interventions or poor functional outcome among SDH patients and should not be used as a criterion for triage to the intensive care unit.

Abstract
Acute subdural hematoma (ASDH) has been a major part of traumatic brain injury. Intracranial hypertension may be followed by ASDH and brain edema. Regardless of the complicated pathophysiology of ASDH, the extent of primary brain injury underlying the ASDH is the most important factor affecting outcome. Ongoing intracranial pressure (ICP) increasing lead to cerebral perfusion pressure (CPP) decrease and cerebral blood flow (CBF) decreasing occurred by CPP decrease. In additionally, disruption of cerebral autoregulation, vasospasm, decreasing of metabolic demand may lead to CBF decreasing. Various protocols for ICP lowering were introduced in neuro-trauma field. Usage of anti-epileptic drugs (AEDs) for ASDH patients have controversy. AEDs may reduce the risk of early seizure (<7 days), but, does not for late-onset epilepsy. Usage of anticoagulants/antiplatelets is increasing due to life-long medical disease conditions in aging populations. It makes a difficulty to decide the proper management. Tranexamic acid may use to reducing bleeding and reduce ASDH related death rate. Decompressive craniectomy for ASDH can reduce patient's death rate. However, it may be accompanied with surgical risks due to big operation and additional cranioplasty afterwards. If the craniotomy is a sufficient management for the ASDH, endoscopic surgery will be good alternative to a conventional larger craniotomy to evacuate the hematoma. The management plan for the ASDH should be individualized based on age, neurologic status, radiologic findings, and the patient's conditions.

The Effect of Goal-Directed Therapy on Patient Morbidity and Mortality After Traumatic Brain Injury: Results From the Progesterone for the Treatment of Traumatic Brain Injury III Clinical Trial. Crit Care Med 2020; 47:623-631.

Abstract
OBJECTIVES To estimate the impact of goal-directed therapy on outcome after traumatic brain injury, our team applied goal-directed therapy to standardize care in patients with moderate to severe traumatic brain injury, who were enrolled in a large multicenter clinical trial. DESIGN Planned secondary analysis of data from Progesterone for the Treatment of Traumatic Brain Injury III, a large, prospective, multicenter clinical trial. SETTING Forty-two trauma centers within the Neurologic Emergencies Treatment Trials network. PATIENTS Eight-hundred eighty-two patients were enrolled within 4 hours of injury after nonpenetrating traumatic brain injury characterized by Glasgow Coma Scale score of 4-12. MEASUREMENTS AND MAIN RESULTS Physiologic goals were defined a priori in order to standardize care across 42 sites participating in Progesterone for the Treatment of Traumatic Brain Injury III. Physiologic data collection occurred hourly; laboratory data were collected according to local ICU protocols and at a minimum of once per day. Physiologic transgressions were predefined as substantial deviations from the normal range of goal-directed therapy. Each hour where goal-directed therapy was not achieved was classified as a "transgression." Data were adjudicated electronically and via expert review. Six-month outcomes included mortality and the stratified dichotomy of the Glasgow Outcome Scale-Extended. For each variable, the association between outcome and either: 1) the occurrence of a transgression or 2) the proportion of time spent in transgression was estimated via logistic regression model. RESULTS For the 882 patients enrolled in Progesterone for the Treatment of Traumatic Brain Injury III, mortality was 12.5%. Prolonged time spent in transgression was associated with increased mortality in the full cohort for hemoglobin less than 8 gm/dL (p = 0.0006), international normalized ratio greater than 1.4 (p < 0.0001), glucose greater than 180 mg/dL (p = 0.0003), and systolic blood pressure less than 90 mm Hg (p < 0.0001). In the patient subgroup with intracranial pressure monitoring, prolonged time spent in transgression was associated with increased mortality for intracranial pressure greater than or equal to 20 mm Hg (p < 0.0001), glucose greater than 180 mg/dL (p = 0.0293), hemoglobin less than 8 gm/dL (p = 0.0220), or systolic blood pressure less than 90 mm Hg (p = 0.0114). Covariates inversely related to mortality included: a single occurrence of mean arterial pressure less than 65 mm Hg (p = 0.0051) or systolic blood pressure greater than 180 mm Hg (p = 0.0002). CONCLUSIONS The Progesterone for the Treatment of Traumatic Brain Injury III clinical trial rigorously monitored compliance with goal-directed therapy after traumatic brain injury. Multiple significant associations between physiologic transgressions, morbidity, and mortality were observed. These data suggest that effective goal-directed therapy in traumatic brain injury may provide an opportunity to improve patient outcomes.

Abstract
Background Traumatic brain injury is associated with high rates of mortality and morbidity. Trauma patients with a coagulopathy have a 10-fold increased mortality risk compared to patients without a coagulopathy. The aim of this study was to identify the incidence of coagulopathy and relate early coagulopathy to clinical outcome in patients with traumatic intracranial hemorrhages. Methods Between September 2015 and December 2016, 108 consecutive cranial trauma patients with traumatic intracranial hemorrhages were included in this study. To assess the relationship between patients with a coagulopathy and outcome, a chi-squared test was performed. Results A total of 29 out of the 108 patients (27%) with a traumatic intracranial hemorrhage developed a coagulopathy within 72 h after admission. Overall, a total of 22 patients (20%) died after admission of which ten were coagulopathic at emergency department presentation. Early coagulopathy in patients with traumatic brain injury is associated with progression of hemorrhagic injury (odds ratio 2.4 (95% confidence interval 0.8–8.0)), surgical intervention (odds ratio 2.8 (95% confidence interval 0.87–9.35)), and increased in-hospital mortality (odds ratio 23.06 (95% confidence interval 5.5–95.9)). Conclusion Patients who sustained a traumatic intracranial hemorrhage remained at risk for developing a coagulopathy until 72 h after trauma. Patients who developed a coagulopathy had a worse clinical outcome than patients who did not develop a coagulopathy.

Abstract
BACKGROUND Anticoagulation therapy is a major risk factor for unfavorable patient outcomes following (traumatic) intracranial hemorrhage. Direct oral anticoagulants (DOAC) are increasingly used for the prevention and treatment of thromboembolic diseases. Data on patients treated for acute subdural hemorrhage (SDH) during anticoagulation therapy with DOAC are limited. METHODS We analyzed the medical records of consecutive patients treated at our institution for acute SDH during anticoagulation therapy with DOAC or vitamin K antagonists (VKA) during a period of 30 months. Patient characteristics such as results of imaging and laboratory studies, treatment modalities and short-term patient outcomes were included. RESULTS A total of 128 patients with preadmission DOAC (n = 65) or VKA (n = 63) intake were compared. The overall 30-day mortality rate of this patient cohort was 27%, and it did not differ between patients with DOAC or VKA intake (26% vs. 27%; p = 1.000). Similarly, the rates of neurosurgical intervention (65%) and intracranial re-hemorrhage (18%) were comparable. Prothrombin complex concentrates were administered more frequently in patients with VKA intake than in patients with DOAC intake (90% vs. 58%; p < 0.0001). DOAC treatment in patients with acute SDH did not increase in-hospital and 30-day mortality rates compared to VKA treatment. CONCLUSIONS These findings support the favorable safety profile of DOAC in patients, even in the setting of intracranial hemorrhage. However, the availability of specific antidotes to DOAC may further improve the management of these patients.

Abstract
We report the case of a patient with anorexia nervosa accompanied by acute subdural haematoma following a fall. A 34-year-old Japanese woman had serious medical complications and brain atrophy. After careful nutritional treatment, her laboratory test results improved and brain atrophy was reversed, and we prevented to perform surgery. However, unexpected prominent oedema of her lower legs and pleural effusion occurred. After receiving treatment for these symptoms, she eventually returned to her former occupation and started following a normal diet. Very few cases of anorexia nervosa accompanied by intracranial haemorrhage have been reported. Coagulation disorder and brain atrophy are supposed to be the primary causes of haematoma formation in the present case. Intracranial haemorrhage likely occurs in patients with anorexia nervosa despite minor head trauma. Because anorexia nervosa is not rare and the age of such patients is advancing, knowledge regarding this disorder would be useful for neurosurgeons.

Abstract
Objective: To demonstrate the usefulness of applying supervised machine-learning analyses to identify specific groups of patients that experience high levels of mortality post-interhospital transfer. Methods: This was a cross-sectional analysis of data from the Health Care Utilization Project 2013 National Inpatient Sample, that applied supervised machine-learning approaches that included (1) classification and regression tree to identify mutually exclusive groups of patients and their associated characteristics of those experiencing the highest levels of mortality and (2) random forest to identify the relative importance of each characteristic’s contribution to post-transfer mortality. Results: A total of 21 independent groups of patients were identified, with 13 of those groups exhibiting at least double the national average rate of mortality post-transfer. Patient characteristics identified as influencing post-transfer mortality the most included: diagnosis of a circulatory disorder, comorbidity of coagulopathy, diagnosis of cancer, and age. Conclusions: Employing supervised machine-learning analyses enabled the computational feasibility to assess all potential combinations of available patient characteristics to identify groups of patients experiencing the highest rates of mortality post-interhospital transfer, providing potentially useful data to support developing clinical decision support systems in future work.

Wiegele M, Schöchl H, Haushofer A, Ortler M, Leitgeb J, Kwasny O, Beer R, Ay C, Schaden E. Diagnostic and therapeutic approach in adult patients with traumatic brain injury receiving oral anticoagulant therapy: an Austrian interdisciplinary consensus statement. Crit Care 2019; 23:62. [PMID: 30795779 PMCID: PMC6387521 DOI: 10.1186/s13054-019-2352-6] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Accepted: 02/10/2019] [Indexed: 12/11/2022] Open
Abstract
There is a high degree of uncertainty regarding optimum care of patients with potential or known intake of oral anticoagulants and traumatic brain injury (TBI). Anticoagulation therapy aggravates the risk of intracerebral hemorrhage but, on the other hand, patients take anticoagulants because of an underlying prothrombotic risk, and this could be increased following trauma. Treatment decisions must be taken with due consideration of both these risks. An interdisciplinary group of Austrian experts was convened to develop recommendations for best clinical practice. The aim was to provide pragmatic, clear, and easy-to-follow clinical guidance for coagulation management in adult patients with TBI and potential or known intake of platelet inhibitors, vitamin K antagonists, or non-vitamin K antagonist oral anticoagulants. Diagnosis, coagulation testing, and reversal of anticoagulation were considered as key steps upon presentation. Post-trauma management (prophylaxis for thromboembolism and resumption of long-term anticoagulation therapy) was also explored. The lack of robust evidence on which to base treatment recommendations highlights the need for randomized controlled trials in this setting.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15112426. [PMID: 30388747 PMCID: PMC6265997 DOI: 10.3390/ijerph15112426] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Revised: 10/25/2018] [Accepted: 10/29/2018] [Indexed: 12/23/2022]
Abstract
Background: We aimed to explore the risk factors that contribute to the mortality of elderly trauma patients with acute subdural hematoma (SDH) resulting from a fall. Mortality rates of the elderly were compared to those of young adults. Methods: A total of 444 patients with acute traumatic subdural hematoma resulting from a fall, admitted to a level I trauma center from 1 January 2009 to 31 December 2016 were enrolled in this study. Patients were categorized into two groups: elderly patients (n = 279) and young adults (n = 165). The primary outcome of this study was patient mortality in hospital. The adjusted odds ratio (AOR) with 95% confidence interval (CI) for mortality was calculated according to gender and pre-existing comorbidities. Univariate and multivariate logistic regression analyses were performed to identify factors related to mortality in the elderly. Results: The odds ratio for mortality caused by falls in the elderly patients was four-fold higher than in the young adults, after adjusting for gender and pre-existing comorbidities. In addition, the presence of pre-existing coronary artery disease (OR 3.2, 95% CI 1.09–9.69, p = 0.035), end-stage renal disease (OR 4.6, 95% CI 1.48–14.13, p = 0.008), hematoma volume (OR 1.2, 95% CI 1.11–1.36, p < 0.001), injury severity score (OR 1.3, 95% CI 1.23–1.46, p < 0.001), and coagulopathy (OR 4.0, 95% CI 1.47–11.05, p = 0.007) were significant independent risk factors for mortality in patients with acute traumatic SDH resulting from a fall. Conclusions: In this study, we identified that pre-existing CAD, ESRD, hematoma volume, ISS, and coagulopathy were significant independent risk factors for mortality in patients with acute traumatic SDH. These results suggest that death following acute SDH is influenced both by the extent of neurological damage and the overall health of the patient at the time of injury.

Timing of INR reversal using fresh-frozen plasma in warfarin-associated intracerebral hemorrhage. Intern Emerg Med 2018; 13:557-565.

Abstract
Rapid reversal of coagulopathy is recommended in warfarin-associated intracerebral hemorrhage (WAICH). However, rapid correction of the INR has not yet been proven to improve clinical outcomes, and the rate of correction with fresh-frozen plasma (FFP) can be variable. We sought to determine whether faster INR reversal with FFP is associated with decreased hematoma expansion and improved outcome. We performed a retrospective analysis of a prospectively collected cohort of consecutive patients with WAICH presenting to an urban tertiary care hospital from 2000 to 2013. Patients with baseline INR > 1.4 treated with FFP and vitamin K were included. The primary outcomes are occurrence of hematoma expansion, discharge modified Rankin Scale (mRS), and 30-day mortality. The association between timing of INR reversal, ICH expansion, and outcome was investigated with logistic regression analysis. 120 subjects met inclusion criteria (mean age 76.9, 57.5% males). Median presenting INR was 2.8 (IQR 2.3-3.4). Hematoma expansion is not associated with slower INR reversal [median time to INR reversal 9 (IQR 5-14) h vs. 10 (IQR 7-16) h, p = 0.61]. Patients with ultimately poor outcome received more rapid INR reversal than those with favorable outcome [9 (IQR 6-14) h vs. 12 (8-19) h, p = 0.064). We find no evidence of an association between faster INR reversal and either reduced hematoma expansion or better outcome.

Abstract
PURPOSE Subdural hematomas (SDH) are associated with seizures and epileptiform discharges, but little is known about the prevalence and impact of seizures, status epilepticus (SE), and epileptiform discharges on outcomes in patients with isolated acute SDH (aSDH). METHODS Continuous EEG reports from 76 adult patients admitted to Rush University Medical Center with aSDH between January 2009 and March 2012 were reviewed. Clinical and radiographic findings, comorbidities, treatment, and outcome parameters, such as mortality, discharge destination, need for tracheostomy/percutaneous endoscopic gastrostomy placement, and length of stay (LOS), were assessed. Univariate and multivariate analyses were performed to assess the impact of clinical seizures, SE, and epileptiform EEG on outcomes. RESULTS Of 76 patients with aSDH who underwent EEG monitoring, 74 (97.4%) received antiseizure prophylaxis. Thirty-two (41.1%) patients had seizures, most of which were clinical seizures. Twenty-four (32%) patients had epileptiform EEG findings. Clinical or nonconvulsive SE was diagnosed in 12 (16%) patients. Clinical seizures were not associated with outcome parameters. Epileptiform EEG findings were independently associated with longer hospital LOS (13 vs. 8 days, P = 0.04) and intensive care unit LOS (10 vs. 4 days, P = 0.002). The SE also predicted longer intensive care unit LOS (10 vs. 4 days, P = 0.002). Neither epileptiform EEG nor SE was significantly related to mortality, discharge destination, or need for tracheostomy/percutaneous endoscopic gastrostomy placement. CONCLUSIONS Seizures and epileptiform EEG findings are very common in patients with aSDH despite antiseizure prophylaxis. While clinical seizures did not affect outcomes, the presence of epileptiform EEG findings and SE was independently associated with longer intensive care unit LOS and hospital LOS.

Abstract
Background: Persistent/recurrent extra-axial hemorrhage may occur after decompression of a subdural hematoma (SDH) followed by an immediate replacement of bone flap. A fenestration of the bone flap may encourage extra-axial fluid absorption; however, the literature has not explored this technique. Methods: Forty-four consecutive patients who underwent surgical decompression of SDH with immediate replacement of bone flap were divided into two groups: Fenestration (F), n = 33, and no fenestration (NF), n = 11. Fenestration involves placement of twist drill holes 1–2 cm apart throughout the bone flap. Clinical data (age, sex, history of antiplatelet/anticoagulation [AA], and presence of drains) were collected. The size of bone flap, postoperative volume, and midline shift (MLS) were measured. A univariate analysis was performed for continuous variables; Fisher's exact test was performed for categorical variables. Results: For postoperative volume, NF group exhibited 94.4 ± 15.5 cm3, while F group exhibited 47.3 ± 15.5 cm3 (P = 0.04); no AA exhibited 62.9 ± 12.3 cm3, while AA exhibited 100.5 ± 19.0 cm3 (P = 0.07); no drains exhibited 110.1 ± 29.6 cm3, while drains exhibited 63.0 ± 9.1 cm3 (P = 0.14). For postoperative MLS, NF group exhibited 4.8 ± 1.1 mm, while F group exhibited 2.5 ± 1.1 mm (P = 0.16); no AA exhibited 2.3 ± 1.0 mm, while AA exhibited 5.8 ± 1.4 mm (P = 0.048); no drains exhibited 4.6 ± 2.2 mm, while drains exhibited 3.8 ± 0.7 mm (P = 0.70). Accounting for fenestration status and AA status: For F group, AA status did not correlate with postoperative volume or MLS significantly; for NF group, history of AA exhibited higher postoperative value 129.2 ± 26.5 cm3, compared to no history of AA at 59.5 ± 16.2 cm3 (P = 0.03). Conclusion: Our results suggest that fenestration prior to the immediate replacement of bone flap after surgical decompression of SDH has the potential to reduce extra-axial fluid accumulation.

Abstract
Warfarin-associated intracranial hemorrhage is associated with a high mortality rate. Ongoing coagulopathy increases the likelihood of hematoma expansion and can result in catastrophic hemorrhage if surgery is performed without reversal. The current standard of care for emergency reversal of warfarin is with fresh frozen plasma (FFP). In April 2013, the USA Food and Drug Administration approved a new reversal agent, 4-factor prothrombin complex concentrate (PCC), which has the potential to more rapidly correct coagulopathy. We sought to determine the feasibility and outcomes of using PCC for neurosurgical patients. A prospective, observational study of all patients undergoing coagulopathy reversal for intracranial hemorrhage from April 2013 to December 2013 at a single, tertiary care center was undertaken. Thirty three patients underwent emergent reversal of coagulopathy using either FFP or PCC at the discretion of the treating physician. Intracranial hemorrhage included subdural hematoma, intraparenchymal hematoma, and subarachnoid hemorrhage. FFP was used in 28 patients and PCC was used in five patients. International normalized ratio at presentation was similar between groups (FFP 2.9, PCC 3.1, p=0.89). The time to reversal was significantly shorter in the PCC group (FFP 256 minutes, PCC 65 minutes, p<0.05). When operations were performed, the time delay to perform operations was also significantly shorter in the PCC group (FFP 307 minutes, PCC 159 minutes, p<0.05). In this preliminary experience, PCC appears to provide a rapid reversal of coagulopathy. Normalization of coagulation parameters may prevent further intracranial hematoma expansion and facilitate rapid surgical evacuation, thereby improving neurological outcomes.

Abstract
Most acute subdural hematomas (ASDHs) develop after rupture of a bridging vein or veins. The anatomy of the bridging vein predisposes to its tearing within the border cell layer of the dura mater. Thus, the subdural hematoma actually forms within the dura. The hematoma grows by continued bleeding into the border cell layer. However, the venous pressure would not be expected to cause a large hematoma. Therefore, some type of mechanism must account for the hematoma's expansion.
Cerebral venous pressure (CVP) has been demonstrated in animal models to be slightly higher than intracranial pressure (ICP), and CVP tracks the ICP as pressure variations occur. The elevation of CVP as the ICP increases is thought to result from an increase in outflow resistance of the terminal portion of the bridging veins. This probably results from a Starling resistor model or, less likely, from a muscular sphincter.
A hypothesis is derived to explain the mechanism of ASDH enlargement. Tearing of one or more bridging veins causes these vessels to bleed into the dural border cell layer. Subsequent ICP elevation from the ASDH, cerebral swelling, or other cause results in elevation of the CVP by increased outflow resistance in the intact bridging veins. The increased ICP causes further bleeding into the hematoma cavity via the torn bridging veins. Thus, the ASDH enlarges via a positive feedback mechanism.
Enlargement of an ASDH would cease as blood within the hematoma cavity coagulates. This would stop the dissection of the dural border cell layer, and pressure within the hematoma cavity would equalize with that in the torn bridging vein or veins.

Abstract
INTRODUCTION Central nervous system (CNS) hemorrhage is a potentially life-threatening condition, especially in patients with acquired coagulopathy. In this setting, treatment of CNS bleeding includes hemostatic therapy to replenish coagulation factors. There is currently a debate over the hemostatic efficacy of plasma in many clinical settings, alongside increasing concern about transfusion-associated adverse events. Despite these concerns, plasma is widely used. Moreover, plasma transfusion practice is variable and there is currently no uniform approach to treatment of traumatic, surgical or spontaneous CNS hemorrhage. This study addresses the need for guidance on the indications and potential risks of plasma transfusion in these settings. An Expert Consensus Panel was convened to develop recommendations guiding the use of plasma to treat bleeding and/or coagulopathy associated with CNS hemorrhage. The panel did not advise on the best treatment available but rather proposed recommendations to be used in the formulation of local procedures to support emergency physicians in their decision-making process. METHODS Evidence was systematically gathered from the literature and rated using methods established by the Scottish Intercollegiate Guidelines Network. The evidence was used to develop graded consensus recommendations, which are presented along with the evidence-based rationale for each in this report. RESULTS Sixty-five articles were identified covering both vitamin K antagonist-anticoagulation reversal and treatment of bleeding/coagulopathy in non-anticoagulated patients. Recommendations were then developed in four clinical scenarios within each area, and agreed on unanimously by all members of the panel. CONCLUSION The Panel considered plasma to be reasonable therapy for CNS hemorrhage requiring urgent correction of coagulopathy, although physicians should be prepared for potential cardiopulmonary complications, and evidence suggests that alternative therapies have superior risk-benefit profiles. Plasma could not be recommended in the absence of hemorrhage or coagulopathy. Consideration of the absolute risks and benefits of plasma therapy before transfusion is imperative.

Abstract
OPINION STATEMENT Clinical presentation, neurologic condition, and imaging findings are the key components in establishing a treatment plan for acute SDH. Location and size of the SDH and presence of midline shift can rapidly be determined by computed tomography of the head. Immediate laboratory work up must include PT, PTT, INR, and platelet count. Presence of a coagulopathy or bleeding diathesis requires immediate reversal and treatment with the appropriate agent(s), in order to lessen the risk of hematoma expansion. Reversal protocols used are similar to those for intracerebral hemorrhage, with institutional variations. Immediate neurosurgical evaluation is sought in order to determine whether the SDH warrants surgical evacuation. Urgent or emergent surgical evacuation of a SDH is largely influenced by neurologic examination, imaging characteristics, and presence of mass effect or elevated intracranial pressure. Generally, evacuation of an acute SDH is recommended if the clot thickness exceeds 10 mm or the midline shift is greater than 5 mm, regardless of the neurologic condition. In patients with patients with an acute SDH with clot thickness <10 mm and midline shift <5 mm, specific considerations of neurologic findings and clinical circumstances will be of importance. In addition, consideration will be given as to whether an individual patient is likely to benefit from surgery. For an acute SDH, evacuation by craniotomy or craniectomy is preferred over burr holes based on available data. Postoperative care includes monitoring of resolution of pneumocephalus, mobilization and drain removal, and monitoring for signs of SDH reaccumulation. Medical considerations include seizure prophylaxis and management as well as management and resumption of antithrombotic and anticoagulant medication.

Abstract
OBJECT A primary goal in the treatment of patients with warfarin-associated subdural hematoma (SDH) is reversal of coagulopathy with fresh-frozen plasma. Achieving the traditional target international normalized ratio (INR) of 1.3 is often difficult and may expose patients to risks of volume overload and of thromboembolic complications. This retrospective study evaluates the risk of mild elevations of INR from 1.31 to 1.69 at 24 hours after admission in patients presenting with warfarin-associated SDH. METHODS Sixty-nine patients with warfarin-associated SDH and 197 patients with non-warfarin-associated SDH treated at a single institution between January 2005 and January 2012 were retrospectively identified. Charts were reviewed for patient age, history of trauma, associated injuries, neurological status at presentation, size and chronicity of SDH, associated midline shift, INR at admission and at hospital Day 1 (HD1), concomitant aspirin or Plavix use, platelet count, and medical comorbidities. Patients were stratified according to use of warfarin and by INR at HD1 (INR 0.8-1.3, 1.31-1.69, 1.7-1.99, and ≥ 2). The groups were evaluated for differences the in rate of radiographic expansion of SDH and in the rate of clinically significant SDH expansion resulting in death, unplanned procedure, and/or readmission. RESULTS There was no difference in the rate of radiographic versus clinically significant expansion of SDH between patients not on warfarin and those on warfarin (no warfarin: 22.3% vs 20.3%, p = 0.866; warfarin: 10.7% vs 11.6%, p = 0.825), but the rate of medical complications was significantly higher in the warfarin subgroup (13.3% for patients who did not receive warfarin vs 26.1% for those who did; p = 0.023). For warfarin-associated SDH, there was no difference in the rate of radiographic versus clinically significant expansion between patients reversed to HD1 INRs of 0.8-1.3 and 1.31-1.69 (HD1 INR 0.8-1.3: 22.5% vs 20%, p = 1; HD1 INR 1.31-1.69: 15% vs 10%, p = 0.71). CONCLUSIONS Mild INR elevations of 1.31-1.69 in warfarin-associated SDH are not associated with a markedly increased risk of radiographic or clinically significant expansion of SDH. Larger prospective studies are needed to determine if subtherapeutic INR elevations at HD1 are associated with smaller increases in risk of SDH expansion.

Abstract
Objective Chronic subdural hematoma (CSDH) is a typical disease that is encountered frequently in neurosurgical practice. The medications which could cause coagulopathies were known as one of the risk factors of CSDH, such as anticoagulants (ACs) and antiplatelet agents (APs). Recently, the number of patients who are treated with ACs/APs is increasing, especially in the elderly population. With widespread use of these drugs, there is a need to study the changes in risk factors of CSDH patients. Methods We retrospectively reviewed 290 CSDH patients who underwent surgery at our institute between 1996 and 2010. We classified them into three groups according to the time of presentation (Group A : the remote period group, 1996-2000, Group B : the past period group, 2001-2005, and Group C : the recent period group, 2006-2010). Also, we performed the comparative analysis of independent risk factors between three groups. Results Among the 290 patients, Group A included 71 patients (24.5%), Group B included 98 patients (33.8%) and Group C included 121 patients (41.7%). Three patients (4.2%) in Group A had a history of receiving ACs/APs, 8 patients (8.2%) in Group B, and 19 patients (15.7%) in Group C. Other factors such as head trauma, alcoholism, epilepsy, previous neurosurgery and underlying disease having bleeding tendency were also evaluated. In ACs/APs related cause of CSDH in Group C, significantly less proportion of the patients are associated with trauma or alcohol compared to the non-medication group. Conclusion In this study, the authors concluded that ACs/APs have more importance as a risk factor of CSDH in the recent period compared to the past. Therefore, doctors should prescribe these medications carefully balancing the potential risk and benefit.

Abstract
Warfarin is a commonly prescribed anticoagulant that may, in selected situations, require rapid reversal of its effects. Several approaches to achieve reversal have been explored, including the administration of prothrombin complex concentrates (PCCs), Many factors can influence determination of an appropriate PCC dose and the resulting effects. Considerations on the use of PCC products to expedite the reversal of warfarin are described.

Abstract
OBJECTIVES Acute subdural hematoma (ASDH) is a life-threatening injury with a high mortality rate. Most ASDH cases are a result of trauma; nontraumatic causes are relatively rare with an incidence rate of 3% to 5%. We report an unusual series of 2 patients, identical twins, who had nontraumatic subdural hematomas 1 year apart, one at age 15 and the other at age 16. METHODS (CASE PRESENTATIONS): Identical twin brothers presented 1 year and 10 days apart to an academic medical center after incurring confusion, decreased mental functioning, and a subsequent comatose state. The injuries occurred while the patients were playing football, but there was no evidence of traumatic blow to the head in either brother. RESULTS Both patients had computed tomographic scans and both underwent emergency surgery for hematoma evacuation. Both patients recovered full neurological function and remained healthy 12 years after surgery. CONCLUSIONS Acute spontaneous subdural hematoma is an emergent medical condition that may result in rapid neurological decline and must be addressed in a timely fashion. After evacuation of the hematoma, intracranial pressure decreases and cerebral perfusion pressure increases, which may allow normal perfusion of the brain. Consequently, prompt recognition and evacuation of an ASDH can drastically improve prognosis. Rarely, subdural hematoma can occur without head injury and should be in the differential diagnosis of athletes who rapidly become comatose.

Abstract
BACKGROUND Emergency reversal of the international normalized ratio (INR) in patients who develop nontraumatic subdural hemorrhage (SDH) due to oral anticoagulants (OAC) represents a primary treatment strategy but it is difficult to predict the amount of prothrombin complex concentrate (PCC) needed for reversal treatment. Moreover, repeated INR testings in central laboratories (CL) are time consuming. The usefulness of point-of-care INR coagulometers (POC) to test the success of INR reversal in OAC-SDH has not yet been investigated. METHODS Prospectively, INR reversal was performed by administering PCC to patients suffering from acute SDH-OAC using a predefined dosing schedule. Accuracy and time gained by using POC were assessed and compared with CL measurements. RESULTS A total of 10 patients were treated according to the protocol (male: 5). Bland-Altman analysis between POC and CL revealed a mean INR deviation of 0.013 for initial INR values and of 0.081 during reversal treatment. Using POC, the median initial net time gain (accounting for clinical examination and CT) for the start of PCC was 21 min. Median total time for POC-documented reversal was 27 min, as compared to 70 min for CL. The shortest interval between head CT and start of emergency SDH evacuation surgery was 37 min. By employing stepwise POC-guided reversal of the anticoagulatory effect of OAC, the calculated PCC dose could be reduced by 25% in the median. CONCLUSIONS Using POC to measure INR values and patient-adapted PCC administration is a fast and economic method to reverse anticoagulation in patients with acute OAC-SDH.

Abstract
Object
Acute subdural hematomas (SDHs) impart serious morbidity and mortality on the elderly population, with only 5% of those older than 65 years of age attaining functional independence. Despite its widespread use, oral antithrombotic therapy (OAT) in the context of acute SDH has not been extensively studied. The authors sought to evaluate the impact of premorbid OAT on recurrence of SDH, radiographic outcome, and mortality in patients undergoing surgical evacuation of an acute SDH.
Methods
The authors conducted a retrospective comparative cohort study reviewing all surgically treated cases of acute SDH at their institution between September 2005 and December 2008. They assessed baseline demographics, coagulation parameters, surgical management, and clinical course. Study end points included additional craniotomy for SDH reaccumulation, follow-up Rotterdam score, recurrent SDH volumetric analysis, Glasgow Outcome Score, and death.
Results
A total of 300 patients with acute SDH treated by craniotomy were assessed. Of these patients, 49% (148 patients) were receiving OAT. Of those who were on a regimen of OAT, 49% were taking warfarin (mean international normalized ratio 3.1 ± 1.8), 31% were receiving antiplatelet therapy, and 20% were on a regimen of a combination of agents. On presentation, 72% of those using OAT received reversal agents. Recurrence of SDH necessitating additional evacuation was not significantly different with respect to premorbid OAT status (13% vs 14%). Patients with a history of OAT did not demonstrate a significant difference in Rotterdam score (2 vs 2), recurrent SDH volume (24.1 vs 19.6 cm3), GOS score (4 vs 3), or mortality (21% vs 24%). These findings remained stable after controlling for age, injury mechanism, and injury severity.
Conclusions
Premorbid OAT was not a significant risk factor for recurrence of SDH necessitating additional evacuation following acute SDH. Additionally, postoperative Rotterdam score, volume of SDH reaccumulation, and overall mortality were not predicted by antithrombotic history. While premorbid use may predispose the patient to an SDH, OAT does not increase the risk of morbidity or mortality following surgical intervention.

Abstract
Object
The purpose of this study was to evaluate the incidence of seizures or epileptiform abnormalities on electroencephalography (EEG) studies in patients undergoing surgical treatment for acute subdural hematoma (SDH).
Methods
This was a retrospective study of 134 consecutive patients with acute or acute-on-chronic SDH who underwent surgical treatment at the authors' institution between January 2004 and July 2008. Detailed information was collected regarding baseline clinical data (including preexistent functional impairment); Glasgow Coma Scale (GCS) sum scores before and 24 hours after surgery; presence of clinical seizures; EEG findings; and functional outcome on discharge and up to the 6-month follow-up. All brain CT scans were reviewed to calculate SDH volume and midline shift. The Glasgow Outcome Scale (GOS) score was used for functional assessment, and GOS scores of 1–3 were considered indicative of poor outcome. Univariate and multivariate logistic regression analyses were performed to identify statistical associations.
Results
Clinical seizures or epileptiform changes on EEG were observed during the acute postoperative period in 33 patients (25%). Preexistent functional impairment and seizures/epileptiform EEG findings after surgery were independently associated with poor functional outcome upon hospital discharge (p < 0.001 for both). Preexistent functional impairment (p < 0.001), lower GCS score before surgery (p = 0.04), and lower GCS score 24 hours after surgery (p = 0.007), but not seizures/epileptiform EEG findings, were independently associated with poor functional recovery at 1- to 6-month follow-up evaluations. Seizures/epileptiform EEG findings had a strong association with lower GCS scores after surgery (p = 0.01), and they were more common in patients who underwent evacuation by craniotomy (p = 0.02).
Conclusions
Epileptic complications are common after acute SDH evacuation, and should be suspected in patients with an unanticipated depressed level of consciousness after surgery. Seizures worsen early functional outcome, but delayed favorable recovery is possible. Therefore, one should be cautious when discussing prognosis in the early postoperative period of patients with epileptic complications.
