Objective: Carotid angioplasty and stenting (CAS) has challenged carotid endarterectomy (CEA) as the therapy of choice for carotid disease. This meta-analysis aims at summarizing the most current body of evidence. Methods: All prospective, controlled clinical trials comparing CEA versus CAS were included. The outcome measures of interest were relative risk (RR) of 30-day stroke, 30-day stroke/death, long-term risk of stroke, and risk of restenosis. Results: The RR of 30-day stroke for CAS was 1.6 times that of CEA (RR 1.6; 95%CI 1.2-2.0, P =.001). The 30-day RR of stroke/death was 1.5 times higher for CAS (RR 1.5; 95%CI 1.1-2.1, P =.008). There was a higher risk of long-term stroke (RR 1.2; 95%CI 1.0-1.5, P =.043). The risk of restenosis was twice for CAS (RR 1.8; 95%CI 1.1-3.1, P =.04). Conclusion: The 30-day RR of stroke, stroke/death, long-term risk of stroke, and risk of restenosis are consistently higher for carotid artery stenting (CAS).
