Abstract

Despite advances in instrumentation and the use of microsurgical techniques, major neurovascular procedures still carry significant risk for neurological deficit. This is, in part, related to our inability to properly monitor brain function in the anesthetized patient and, thus, interpret the effects, beneficial or otherwise, of our various intraoperative manipulations. Raw electroencephalogram (EEG) activity, compressed spectral array, and cerebral blood flow have all been used to monitor the central nervous system during surgery, but these techniques are cumbersome, the results obtained not uniform, and their reliability inconsistent.
