Various anesthetic and surgical techniques have been recommended with or without cerebral function monitoring in attempts to reduce the risk of carotid endarterectomy, but there is no consensus as to the ideal method for performing this procedure. General anesthesia is now the most common anesthetic technique used, but of 337 carotid endarterectomies performed by the author's service from 1981 through 1985, 305 (91%) were conducted with regional anesthesia. This paper presents the morbidity and mortality rates for those patients. There were two perioperative transient ischemic attacks (0.66%), two perioperative strokes (0.66%), and two perioperative deaths (0.66%). No patient in the series suffered a myocardial infarction within 30 days after endarterectomy. This series demonstrates that carotid endarterectomy can be performed with good results using regional anesthesia, which facilitates intraoperative cerebral function monitoring. Regional anesthesia is associated with a very low incidence of postoperative hypertension and perioperative myocardial infarction.
