Intraoperative use of somatosensory evoked potentials for brain monitoring during carotid surgery.
Somatosensory evoked potentials (SSEP) are a valuable clinical tool in the operating theater. Multichannel SSEP monitoring is an objective measure of CBF and cerebral function. The monitoring of the SSEP during carotid surgery is a simple and reliable method of determining the effect of carotid clamping on CBF and the need for shunting. The diagnosis sensitivity and specificity of intraoperative SSEP monitoring for assessing the neurologic outcome of patients are over 95%. At least 16.1% of cases required shunt placement using SSEP monitoring.
