Endovascular coiling versus neurosurgical clipping in the management of aneurysmal subarachnoid haemorrhage in the elderly: a multicenter cohort study.

The comparability of endovascular coiling over neurosurgical clipping has not been firmly established in elderly patients with aneurysmal subarachnoid haemorrhage (aSAH). Data were obtained from all patients with aSAH aged ≥60 across three tertiary hospitals in Singapore from 2014 to 2019. Outcome measures included modified Rankin Scale (mRS) score at 3 and at 6 months, and in-hospital mortality.

Diagnostic dilemma in acute neurological presentation of spinal arachnoid cysts: A case report.

Background: Spinal arachnoid cysts are relatively uncommon, cerebrospinal fluid-filled sacs formed by arachnoid membranes that can be either idiopathic or acquired. The neurological presentation of these cysts is varied. Advances in imaging techniques have allowed an improved characterization of these entities and excluded other possible causes of clinical manifestation.

Impact of time to resumption of antithrombotic therapy on outcomes after surgical evacuation of chronic subdural hematoma: A multicenter cohort study.

Background: The decision to resume antithrombotic therapy after surgical evacuation of chronic subdural hematoma (CSDH) requires judicious weighing of the risk of bleeding against that of thromboembolism. This study aimed to investigate the impact of time to resumption of antithrombotic therapy on outcomes of patients after CSDH drainage.

Methods: Data were obtained retrospectively from three tertiary hospitals in Singapore from 2010 to 2017.

Development of a prognostic scoring system to predict risk of reoperation for contralateral hematoma growth after unilateral evacuation of bilateral chronic subdural hematoma.

Bilateral chronic subdural hematoma (bCSDH) is frequently drained unilaterally when the contralateral CSDH is small and asymptomatic. However, reoperation rates for contralateral CSDH growth can be high. We aimed to develop a prognostic scoring system to guide the selection of suitable patients for unilateral drainage of bCSDH.

Outcomes of Subdural Versus Subperiosteal Drain After Burr-Hole Evacuation of Chronic Subdural Hematoma: A Multicenter Cohort Study.

Background: Although the use of a postoperative drain after burr-hole evacuation of chronic subdural hematoma (CSDH) is known to improve surgical outcomes, the superiority of subdural over subperiosteal drains has not been firmly established. Evidence comparing these 2 drain types is largely restricted to single-center series with limited numbers. Using a multicenter cohort study, we aimed to show noninferiority of subperiosteal drains vis-à-vis subdural drains after burr-hole evacuation of CSDH.

Body mass index and the risk of postoperative cerebrospinal fluid leak following transsphenoidal surgery in an Asian population.

Introduction: Postoperative cerebrospinal fluid (CSF) leak is a serious complication following transsphenoidal surgery for which elevated body mass index (BMI) has been implicated as a risk factor, albeit only in two recent North American studies. Given the paucity of evidence, we sought to determine if this association holds true in an Asian population, where the BMI criteria for obesity differ from the international standard.

Methods: A retrospective study of 119 patients who underwent 123 transsphenoidal procedures for sellar lesions between May 2000 and May 2012 was conducted.
