Current Topics in Cerebral Vasospasm
Although considerable improvement in operative mortality and morbidity has been made in the past 15 years in patients with subarachnoid hemorrhage (SAH) from cerebral aneurysms, many reports document the lack of similar improvement in case morbidity and mortality [1, 3]. A major contributing factor to the persistently high morbidity of SAH is the development of cerebral vasospasm and ischemia which leads to progressive ischemic neurological deficits during the first 5–9 days after SAH [1, 3, 4, 5]. Vasospasm is found by angiography in as many as 70% of patients, and symptomatic vasospasm develops in 20%–30% of patients following SAH. Cerebral vasospasm with secondary ischemia is the leading cause of death and disability among patients with aneurysmal SAH .
