Pharmacologic Management of Cerebral Vasospasm in Aneurysmal Subarachnoid Hemorrhage.

Keaton S Smetana, Pamela L Buschur, Jocelyn Owusu-Guha, Casey C May,

Aneurysmal subarachnoid hemorrhage (aSAH) is responsible for 5% to 10% of all strokes in the United States annually and is a neurologic emergency with considerable morbidity and mortality. A common complication of aSAH is cerebral vasospasm (CVS) or narrowing of the cerebral arteries. While nearly 70% of aSAH patients will ... Read more >>
