Carotid endarterectomy (CEA) has remained the first choice of treatment in preventing ischemic stroke due to symptomatic stenosis of the internal carotid artery despite other new available options. During CEA patients are first and foremost at risk of cerebral as well as myocardial ischemia, therefore, maintenance of the oxygen supply to the brain and the myocardium is of outstanding importance requiring reliable monitoring of cerebral and cardiac function. The regional versus general anesthesia debate is an age-old one that has brought few definite answers regarding the impact on postoperative outcome of either anesthetic technique. Up to now, there is little evidence from only a few randomized clinical trials to demonstrate the superiority of either anesthetic technique with respect to outcome parameters. Because the level of evidence in favor of regional anesthesia during CEA can at least be rated between 1(-) and 2(+) the resulting recommendation is grade C. The purpose of the review is to highlight the characteristics and goals of anesthetic management during CEA.
