SEP and EEG Monitoring During Carotid Surgery
A great deal of arterial pathology responsible for ischemic alterations of the brain is amenable today to surgical treatment, particularly when it involves the extracranial carotid arteries. Perioperative neurologic complications still range from 1 to l0%

Foreword In June 1986, the Institute of Neurosurgery, University of Milano, with the generous help of Amplifon SpA, organized an international symposium on the use of evoked potentials for monitoring nervous functions during surgical procedures and in treating patients admitted to intensive care units. We are personally convinced that this monitoring technique has definite and objective validity; we wanted to compare our experience with that of other groups working in the field to confirm our data and, if possible, to extend applications to other areas. The possibility of knowing during a surgical operation whether the procedures we perform are in themselves harmless or dangerous is an irreplaceable help in the progress of neurosurgical technique. Evoked potential monitoring appears to be specific and reliable, unlike other methods of nervous system monitoring that were available in the past. In fact, the evaluation of neurological signs is necessarily very scanty during anesthesia and intraoperative electroencephalography is highly aspecific. It was mandatory to compare different experiences from all over the world, in order to assess the reliability of intraoperative evoked potential monitoring, its possible applications and its limitations. As concerns head-injured patients in the intensive care unit, needed is a diagnostic tool more precise than clinical evaluation (which is always subjective) and
