Abstract:
Somatosensory evokd responses(SSERs) and auditory evoked responses(AERs) were studied in 33 patients with cerebral aneurysms and arteriovenous malformations(AVMs) to see if these tests were useful indicators of cerebral vasospasm. 7/21 had abnormal SSER and 5/28 an abnormal AER. The SSER was abnormal in 4/7 patients with severe vasospasm but in only 1/13 without spasm or with mild or moderate spasm. Abnormal SSERs in patients with severe vasospasm indicated a poor prognosis. Abnormalities on the SSER and AER correlated best with the degree of clinical deficit. These tests seemed insufficiently sensitive to reliable detect impending ischemia.
