Objectives Several studies have shown the beneficial role of statins in reducing the risk of major perioperative complications and death associated with noncardiac vascular surgery, but few have focused on their effects in the event of carotid endarterectomy (CEA). This study analyzes the effects of preoperative statin use on perioperative outcomes in patients undergoing CEA. Materials and Methods Data from all consecutive patients who underwent primary CEA for symptomatic and asymptomatic carotid disease between 2002 and 2014 at a single institution were prospectively stored in a vascular surgery registry, recording risk factors, medication, and indication for surgery. Endpoints of the study were perioperative (30‐day) stroke and death. Results Overall, 784 patients were on statins (825 CEAs, Group I), while 494 were not (545 CEAs, Group II). There were two perioperative strokes in Group I (0.24%) and four in Group II (0.73%; p = .22), and no deaths. The only nonfatal cardiac complication occurred in Group II (0.18%, p = .39). A neurologist assessed patients at 1, 6, and 12 months after CEA, and every 2 years thereafter. Follow‐up (range: 0.1–13 years; mean, 6.3 ± 3.7 years) was obtained for 1,239 patients (1,326 CEAs). Because 165 patients (166 CEAs) crossed over from Group II to Group I during the follow‐up time, long‐term data were stratified by postoperative statin treatment rather than by preoperative statin use. The 5‐ and 10‐year restenosis/occlusion and survival rates did not differ significantly between the two groups. Conclusions Taking statins prior to CEA did not seem to affect the risk of major perioperative ischemic events and death, most likely due to the extremely low overall incidence of perioperative complications.
