Cerebral venous sinus thrombosis following post-neurosurgical intracranial hypotension: A case report and systematic review of the literature

Abstract

Cerebral venous sinus thrombosis (CVST) following brain surgery is a feared complication, commonly described after direct injury to the sinus. However, distant CVST occurring away from the operative area are unexpected. Yet, there is a strong physio-pathological rational supporting the role of intracranial hypotension as a risk factor of CVST. Here, we report the case of a frontal arachnoid cyst depletion followed by an extensive contralateral CVST. Given the major prognostic consequences observed in this clinical illustration, we further investigated the hypothesis of intracranial hypotension as an etiology of CVST by carrying out a systematic review of the literature.
