Abstract

Stroke is the third leading cause of death and the leading cause of disability in contemporary society. Aneurysmal subarachnoid hemorrhage (aSAH) is a hemorrhagic stroke which accounts for 7% of all stroke cases and 22 to 25% of cerebrovascular deaths. Aneurysmal subarachnoid hemorrhage is a very complex disease and many controversies on its pathophysiology and management have not yet been settled. The aim of this review is to present the most recent evidence-based advances in the pathophysiology and perioperative management of aSAH.

Keywords: Subarachnoid hemorrhage, vasospasm, stroke, delayed neurologic deficits.
