OBJECTIVE: To compare carotid artery stenting with open carotid surgery for the treatment of symptomatic or asymptomatic carotid artery stenosis in terms of stroke, myocardial infarction, and death at 30 days. DESIGN: A meta-analysis of parallel randomized clinical trials (RCTs) (blind or open) published (full article available) in English. SETTING: University-based electronic search. INTERVENTIONS: Patients were submitted to carotid artery stenting or open carotid artery surgery. MEASUREMENTS AND MAIN RESULTS: Ten RCTs including 6,950 patients were found. There was a moderate amount of heterogeneity (I(2) = 49.8%) in stroke at 30 days when all available data were added together. Heterogeneity fell to 0% when only studies (n = 4) in which cerebral protection devices were used in a high percentage of the patients in the stenting groups were retained. Those 4 studies included 5,012 patients. Carotid endarterectomy reduced the risk ratio (RR) of stroke at 30 days compared with stenting (RR = 0.50; 95% confidence interval (CI), 0.38-0.67; p = 0.000002; event rate 2.8% and 5.6%). Carotid endarterectomy increases the risk of myocardial infarction (RR = 2.16 [95% CI, 1.32-3.54], p = 0.002, heterogeneity 0%, event rate 1.8% and 0.9%). There was no difference in death at 30 days (RR = 0.72 [0.42-1.24] (random effects model), p = 0.23, I(2) = 2.45%, p value for heterogeneity = 0.41; event rate 0.7% and 1.1% for carotid endarterectomy and stenting, respectively). CONCLUSIONS: Compared with stenting, carotid endarterectomy decreases the risk of stroke at 30 days, increases the risk of myocardial infarction, and does not affect the risk of death.
