Endovascular Treatment for Cerebral Venous Thrombosis: Applying Lessons Learned from Clinical Trials of Endovascular Treatment in Acute Arterial Ischemic Stroke.

Abstract

Background: Cerebral venous thrombosis (CVT) is a rare but severely disabling form of stroke. Acute treatment mainly consists of medical management, since there is no robust evidence suggesting the benefit of endovascular treatment for CVT. Given the relative lack of data to guide acute treatment decision-making, CVT treatment decisions are mostly made on a case-by-case basis. In some ways, the current status quo of endovascular treatment for CVT resembles the state of endovascular treatment for acute ischemic stroke before the wave of major positive large vessel occlusion endovascular treatment trials in 2015.

Summary: The current state of evidence with regard to endovascular CVT treatment is summarized, parallels to acute ischemic stroke are drawn, and it is discussed how the lessons learned from the evolution of acute ischemic stroke endovascular treatment (EVT) trials could be applied to designing a trial of endovascular treatment for CVT. The review ends by outlining possible scenarios for the future of endovascular CVT treatment.

Key messages: CVT is a serious disease, affecting young patients and their families, and harbors a considerable social and economic burden. Working toward high-level evidence for the best possible treatment strategy and exploring a possible role for EVT to improve outcomes in CVT needs to remain a high priority in stroke research.
