ABSTRACTcommon clinical entities encountered by any neurosurgical service.Brain herniation due to posttraumatic hematoma remains one of the most difficult situation faced by neurosurgeons, and causes significant mortality and morbidity. To our knowledge there were only few past studies focused especially into the herniated subgroup of traumatic extraaxial hematomas (31,37,43,44).The aim of this retrospective study was to assess the surgical outcome and the prognostic importance of clinical and █ INTRODUCTION A ccident is the leading cause of death among individuals younger than 45 years. Traumatic brain injury (TBI) accounts for approximately 70% of these traumatic deaths and most of the unfavorable outcomes (2). The most important complication of TBI is the development of intracranial hematomas. It is estimated that intracranial hematomas occur in 25-45% of severe TBI, 3-12% of moderate cases and approximately 1 in 500 patients with mild TBI (40). As a result, acute traumatic extraaxial hematomas (epidural hematoma (EDH) and subdural hematoma (SDH)), are among the most AIm: The aim of this study was to assess the surgical outcome and the prognostic importance of clinical and radiological data of patients operated emergently for an extraaxial hematoma causing brain herniation. mATERIAl and mEThODS:This retrospective study comprised 108 adult patients who were operated due to herniated traumatic extraaxial hematomas from January 2000 to January 2013. RESUlTS:Of 108 patients, 63 patients (58.3%) were diagnosed as subdural hematoma (SDH), and 45 patients (41.7%) as epidural hematoma (EDH). An unfavorable outcome was significantly increased for patients who were diagnosed as SDH (90.4%) compared with EDH patients (33.3%). Mortality rate for herniated SDH patients was 65.1%, and 26.6% for herniated EDH patients. High mortality and unfavorable outcome ratios were associated with Glasgow Coma Scale scores at admission, mean postoperative intracranial pressure (ICP) values, type of the brain herniation, interval from the time of trauma to the time of hematoma decompression, the duration of the brain herniation, intraoperative acute brain swelling, hematoma volume and thickness, degree of the midline shift and the obliteration of the basal cisterns. CONClUSION:Our data showed that, postoperative ICP values were one most important predictor of the mortality. We recommended postoperative ICP monitoring for all patients presenting with the brain herniation due to traumatic extraaxial hematoma.

OBJECTIVEIsolated acute subdural hematoma (aSDH) is increasing in older populations and so is the use of oral anticoagulant therapy (OAT). The dramatic increase of OAT—with direct oral anticoagulants (DOACs) as well as with conventional anticoagulants—is leading to changes in the care of patients who present with aSDH while receiving OAT. The purpose of this study was to determine the management and outcome of patients being treated with OAT at the time of aSDH presentation.METHODSIn this single-center, retrospective study, the authors analyzed 116 consecutive cases involving patients with aSDH treated from January 2007 to June 2016. The following parameters were assessed: patient characteristics, admission status, anticoagulation status, perioperative management, comorbidities, clinical course, and outcome as determined at discharge and through 6 months of follow-up. Oral anticoagulants were classified as thrombocyte inhibitors, vitamin K antagonists, and DOACs. Patients were stratified based on which type of medication they were taking, and subgroup analyses were performed. Predictors of unfavorable outcome at discharge and follow-up were identified.RESULTSOf 116 patients, 74 (64%) had been following an OAT regimen at presentation with aSDH. The patients who were taking oral anticoagulants (OAT group) were significantly older (OR 12.5), more often comatose 24 hours postoperatively (OR 2.4), and more often had ≥ 4 comorbidities (OR 3.2) than patients who were not taking oral anticoagulants (no-OAT group). Accordingly, the rate of unfavorable outcome was significantly higher in patients in the OAT group, both at discharge (OR 2.3) and at follow-up (OR 2.2). Of the patients in the OAT group, 37.8% were taking a thrombocyte inhibitor, 54.1% a vitamin K antagonist, and 8.1% DOACs. In all cases, OAT was stopped on discovery of aSDH. For reversal of anticoagulation, patients who were taking a thrombocyte inhibitor received desmopressin 0.4 μg/kg, 1–2 g tranexamic acid, and preoperative transfusion with 2 units of platelets. Patients following other oral anticoagulant regimens received 50 IU/kg of prothrombin complex concentrates and 10 mg of vitamin K. There was no significant difference in the rebleeding rate between the OAT and no-OAT groups. The in-hospital mortality rate was significantly higher for patients who were taking a thrombocyte inhibitor (OR 3.3), whereas patients who were taking a vitamin K antagonist had a significantly higher 6-month mortality rate (OR 2.7). Patients taking DOACs showed a tendency toward unfavorable outcome, with higher mortality rates than patients on conventional OAT or patients in the vitamin K antagonist subgroup. Independent predictors for unfavorable outcome at discharge were comatose status 24 hours after surgery (OR 93.2), rebleeding (OR 9.8), respiratory disease (OR 4.1), and infection (OR 11.1) (Nagelkerke R2 = 0.684). Independent predictors for unfavorable outcome at follow-up were comatose status 24 hours after surgery (OR 12.7), rebleeding (OR 3.1), age ≥ 70 years (OR 3.1), and 6 or more comorbidities (OR 3.1, Nagelkerke R2 = 0.466). OAT itself was not an independent predictor for worse outcome.CONCLUSIONSAn OAT regimen at the time of presentation with aSDH is associated with increased mortality rates and unfavorable outcome at discharge and follow-up. Thrombocyte inhibitor treatment was associated with increased short-term mortality, whereas vitamin K antagonist treatment was associated with increased long-term mortality. In particular, patients on DOACs were seriously affected, showing more unfavorable outcomes at discharge as well as at follow-up. The suggested medical treatment for aSDH in both OAT and no-OAT patients seems to be effective and reasonable, with comparable rebleeding and favorable outcome rates in the 2 groups. In addition, prior OAT is not a predictor for aSDH outcome.

OBJECTIVEAcute subdural hematoma (aSDH) is a common disease increasing in prevalence given the demographic growth of the aging population. Yet, the benefit of surgical treatment for aSDH and the subsequent functional outcome in elderly patients (age ≥ 80 years) remain unclear. Therefore, the aims of this study were to evaluate the incidence of aSDH in patients 80 years or older, determine overall functional outcome, identify predictors of an unfavorable or favorable outcome, and establish specific risk factors for seizures.METHODSThe authors retrospectively analyzed patients 80 years and older who presented with isolated aSDH in the past 10 years at their institution. The following parameters were assessed: baseline characteristics, clinical status on admission and 24 hours after surgery, and clinical course. Functional outcome was assessed at discharge and the 3-month follow-up (FU).RESULTSIn the period from January 2007 to December 2016, 165 patients with aSDH were admitted to the authors’ institution. Sixty-eight patients (41.2%) were 80 years old or older, and the mean age overall was 85 years (range 80–96 years). The incidence of aSDH in the elderly had significantly increased over past decade, with more than 50% of patients admitted to our institution for aSDH now being 80 years or older. The overall mortality rate was 28% at discharge and 48% at the FU. Independent predictors of an unfavorable outcome at discharge were a GCS score ≤ 8 at 24 hours after operation (p < 0.001) and pneumonia (p < 0.02). At the FU, a GCS score ≤ 8 at 24 hours after operation (p < 0.001) and cumulative comorbidities (≥ 5; p < 0.05) were significant independent predictors. All patients with more than 6 comorbidities had died by the FU. Surgical treatment in comatose compared to noncomatose patients had statistically significant, higher mortality rates at discharge and the FU. Still, 23% of the comatose patients and more than 50% of the noncomatose patients had a favorable outcome at the FU (p = 0.06).CONCLUSIONSThe number of octo- and nonagenarians with aSDH significantly increased over the last decade. These patients can achieve a favorable outcome, especially those with a noncomatose status and fewer than 5 comorbidities. Surgical and nonsurgical treatment of octo- and nonagenarians during and after discharge should be optimized to increase clinical improvement.
