Routine completion study during carotid endarterectomy is not necessary

The results of many studies have suggested the need for a completion study during carotid endarterectomy (CE). This paper describes our experience not routinely using completion studies. We retrospectively reviewed the charts of 417 patients who underwent 455 CEs. Demographic features, risk factors, ipsilateral neurologic events during the first 30 days, and mortality data were identified. There were 14 neurologic events and 4 deaths. No technical defects were found in 13 patients; 1 patient did not have exploratory surgery after an occlusion. Long-term follow-up shows 10 of the 14 arteries are open. Two patients were lost to follow-up, 1 patient died, and 1 artery was not explored. We conclude that CE may be carried out without routinely using a completion study, with an acceptable postoperative neurologic complication rate. Careful technique is mandatory.
