Postoperative Cerebral Venous Sinus Thrombosis Following Retrosigmoid Craniotomy for a Cerebellopontine Angle Tumor: A Clinical and Radiological Analysis

Introduction: The retrosigmoid approach (RSA) is one of the most common approaches to the posterolateral skull base. Postoperative cerebral venous sinus thrombosis (CVST) is a rare but known complication following RSA. There is a paucity of literature regarding CVST. To overcome this lack, we performed radiological and clinical analyses to report our experience with CVST after RSA.
