Aneurysmal Subarachnoid Hemorrhage

摘要

It is estimated that subarachnoid hemorrhage (SAH) from ruptured cerebral aneurysm affects approximately 30,000 Americans each year. More than one-third die within the first month despite optimal treatment, and, of those who survive, approximately half will have significant neurologic deficit (Mayberg et al., 1994). SAH occurs when a vessel on the surface of the brain ruptures, forcing blood into the subarachnoid space (American Stroke Association, 2004).
