Carotid endarterectomy under regional anesthesia.
Regional anesthesia for carotid endarterectomy is a simple, reliable, and virtually complication-free technique. We began to perform a series of carotid endarterectomy under regional anesthesia at our institution in May 1990. This report describes our experience with 180 operated patients from May 1990 till December 1995, with regional anesthesia. All patients were operated with microsurgery and we utilized the deeply cervical plexus block at the C-4 level associated with superficial block, along the posterior border of the externocleidomastoid muscle. The main advantage of this technique of anesthesia is that it is the only exact method of assessing the need of a shunt by using the neurological status of the awaken patient during trial carotid cross-clamping. The regional anesthesia allows carotid endarterectomy to be safely performed on patients with advanced cardiac disease or severe chronic obstructive pulmonary disease who were not good candidates for general anesthesia. In this 180 patients we performed 198 consecutive endarterectomies (10% bilateral) with a total morbidity-mortality rate of 2.0%.
