ObjectivePatients with cerebral venous sinus thrombosis (CVST) may die during the acute phase due to increased intracranial pressure and cerebral herniation. The purpose of this study was to assess the role of decompressive craniectomy in the treatment of patients with malignant CVST.MethodsPatients who underwent decompressive craniectomy and were consequently admitted to the Critical Care Unit, Department of Neurosurgery, at Capital Medical University Xuanwu Hospital from March 2010 to January 2021 were retrospectively examined with follow-up data at 12 months.ResultsIn total, 14 cases were reviewed, including 9 female and 5 male patients, aged 23-63 years (42.7 ± 12.3 years). Prior to surgery, all patients had a GCS score <9. 6 patients had a unilateral dilated pupil, while 4 patients had bilateral dilated pupils. According to the head computed tomography (CT), all patients had hemorrhagic infarction, and the median midline shift was 9.5 mm before surgery. Thirteen patients underwent unilateral decompressive craniectomy, and 1 patient underwent bilateral decompressive craniectomy, among whom, 9 patients underwent hematoma evacuation. Within 3 weeks of surgery, 3 cases (21.43%) resulted in death, with 2 patients dying from progressive intracranial hypertension and 1 from acute respiratory distress syndrome (ARDS). Eleven patients (78.57%) survived after surgery, of whom 4 (28.57%) patients recovered without disability at 12-month follow-up (mRS 0-1), 2 (14.29%) patients had moderate disability (mRS 2-3), and 5 (35.71%) patients had severe disability (mRS 4-5).ConclusionsEmergent decompressive craniectomy may provide a chance for survival and enable patients with malignant CVST to achieve an acceptable quality of life (QOL).Copyright © 2023 Elsevier Inc.
