AbstractPrevious studies have documented the safety and efficacy of general surgery residents and vascular fellows performing carotid endarterectomy (CEA) under the supervision of an attending surgeon. With the proper supervision of the attending surgeon, these operations can be performed with an acceptably low perioperative stroke and mortality rate. The question remains, however, whether these desirable results can be obtained by general surgery residents when operating on awake patients under regional block (RB) anesthesia. We set out to determine whether it is prudent to promote this technique in this teaching setting. We analyzed 128 CEAs performed at a community teaching hospital training three chief residents a year. These operations were performed by residents under the direct supervision of a single attending vascular surgeon. RB was preferred and was used in 67 operations. General anesthesia (GA) was used in the remaining 61 procedures. Overall mortality was 0 per cent. Patients in the RB group were converted intraoperatively to GA in 4 of 67 (6%) procedures. There was one perioperative stroke in this series (1/128, 0.78%), occurring in a patient under RB (1/67, 1.5 %) leaving the patient with a minor sensory deficit. No strokes occurred in the GA group. There were five temporary cranial nerve deficits (3.9%). Three were in the RB group (4.5%) and two in the GA group (3.3%). General surgery residents can be trained in the performance of carotid endarterectomy using regional block anesthesia in awake patients without compromising patient safety. Suggestions to the effect that only attending physicians and/or vascular fellows can perform these procedures under regional block are without merit.
