Abstract TP46: Evaluation of Aspiration Thrombectomy versus Anticoagulation in a Large Cohort of Patients With Cerebral Venous Sinus Thrombosis

Introduction: Cerebral venous sinus thrombosis (CVST) is an uncommon cause of stroke. Studies have assessed the efficacy of aspiration thrombectomy (AT), but have been limited to smaller populations, and AT was often reserved for patients with worsening neurological deterioration, which itself portends a poor prognosis. Purpose: To compare outcomes of AT vs. medical management (MM) in a large referral population without neurological deterioration at a single Comprehensive Stroke Center. Methods: We retrospectively identified patients using ICD-10 codes within our network between 2007-2017. Baseline demographics and clinical data were abstracted. Mann-Whitney U test and chi-square test were used for continuous and categorical variables, respectively. Results: 383 patients were identified, and 99 were excluded due to age Conclusion: This study shows that MM was more likely to have a favorable outcome at discharge than AT. No difference in outcome measured at 3, 6 and 12 months was seen.
