Safety and clinical outcomes in endovascular treatment for symptomatic cerebral venous thrombosis: a single-center experience with meta-analysis.

Abstract

The role of mechanical thrombectomy (MT) in cerebral venous sinus thrombosis (CVT) is ambiguous. This study aims to share our experience with MT in CVT, supplemented by a meta-analysis on this treatment. All patients who had MT for CVT at our institution, between 2016 and 2021, were retrospectively reviewed for treatment indications, the technique used, success and complication rates, and clinical outcomes. A meta-analysis was performed for clinical and safety outcomes from published literature with > 10 patients. A total of 15 patients were included in this study. All had a venous hemorrhage or deteriorating despite anticoagulation. MT was performed using aspiration (with wide bore catheters) in 7 patients: aspiration with stent retriever in 5 and transjugular Fogarty-balloon thrombectomy in 3 patients. Adjunctive intra-sinus thrombolysis (IST) was used in 4 cases and venoplasty in 3. Technical success (restoring antegrade venous flow on arterial injection) was 100% with no procedure-related major complication. The direct transjugular approach was cheaper and faster. At 3-month follow-up, 86% of patients had good outcomes (MRS < 2). Meta-analysis of clinical and safety outcomes from 22 and 20 studies, respectively, demonstrated a positive association between MT and good outcomes as well as no significant association with hazardous periprocedural events. EVT via mechanical means for CVT is feasible in our series and meta-analysis. From our experience, trans-jugular Fogarty balloon embolectomy seems to be a potential cost-saving option, at least in a certain part of the world.
