Cerebral vasospasm is one of most serious complication after subarachnoid hemorrhage due to aneurysmal rupture and a very important cause affecting to prognosis. The most reliable diagnostic assessment of cerebral vasospasm is angiography, but this is limited to perform because of complications such as neurological deficits or death, especially to repeat study. It seems likely that assessment of evoked electrical activity, a much simpler and safer than the repeated study of angiogrpay, will be of use in following the condition of patients with clinical vasospasm following SAH In order to study relationship between clinical vasospasm and electrical activity, we traced SSEP from upper extremity by median nerve stimulation and lower extremity by posterior tibial stimulation which manifest the neurophysiologic function of cerebral ischemia. MN(Median n.) and PTN(Posterior tibial n.) were performed simultaneously. Over 2 years period (1986 through 1988), 41 patients were performed SSEP and evaluated the relationship between SSEP and clinical or angiographic vasospasm in patients of SAH.
