ObjectiveThe purpose of this study was to compare carotid endarterectomy (CEA) plus medical therapy (MT) with MT alone for symptomatic and asymptomatic patients suffering from carotid artery stenosis in terms of long-term stroke/death rate.DesignA meta-analysis of parallel randomized, controlled trials (RCTs) (blind or open) published in English.SettingA university-based electronic search.ParticipantsPatients suffering from carotid artery stenosis symptomatic or not.InterventionsPatients were subjected to CEA plus MT or MT alone.Measurements and Main ResultsFor asymptomatic patients, 6 RCTs comprising 5,733 patients (CEA = 2,853 and MT = 2,880) were included. CEA did not affect the stroke/death risk for asymptomatic patients (risk ratio [RR] = 0.93; 95% confidence interval [CI], 0.84 to 1.02; I2 = 0%; p = 0.14). For symptomatic patients, 2 RCTs were included. They had 5,627 patients (CEA = 3,069 and MT = 2,558) of whom 2,295 patients (CEA = 1,213; MT = 1,082) had severe stenosis (North American Symptomatic Carotid Endarterectomy Trial [NASCET] technique ≥50% and European Carotid Surgery Trial technique ≥70%). CEA decreased the stroke/death risk only for patients with severe stenosis (RR = 0.69; 95% CI, 0.59-0.81; p < 0.001 [random effects model]; I2 = 0% on the odds ratio and 17% on the RR [benefit or harm side]; number needed to treat = 11 [95% CI, 8-17]).ConclusionsCEA is helpful for recently symptomatic patients with carotid artery stenosis ≥50% (NASCET technique) but adds no benefit in terms of stroke/death for asymptomatic patients.
