Angiographic Treatment of Asymptomatic Cerebral Vasospasm Following Aneurysmal Subarachnoid Hemorrhage for the Prevention of Delayed Cerebral Ischemia.

Objective: Angiographic treatment of asymptomatic cerebral vasospasm (CVS) in aneurysmal subarachnoid hemorrhage remains controversial. We sought to investigate its relationship with the development of delayed cerebral ischemia.

Methods: Consecutive patients admitted between July 2017 and June 2019, with a diagnosis of aneurysmal subarachnoid hemorrhage, were retrospectively analyzed.
