Abstract:
ObjectiveTo evaluate the long-term outcomes of carotid endarterectomy versus carotid artery stenting for carotid stenosis.MethodsPubMed, EMBASE, and the Cochrane databases were retrieved.The randomized controlled trials of comparing CEA with CAS in patients with carotid artery stenosis were enrolled.The data such as the research basic characteristics and the long-term outcomes including stroke or death combined endpoints, any stroke or any death were extracted.The Stata software was used to conduct statistical analysis.ResultsA total of 7 randomized controlled trials and 8 210 patients were included.The median follow-up time was 2-7.4 years.The overall quality of the included studies was high and the risk of bias was low.The meta-analysis showed that the risks of the combined endpoint of stroke or death (hazard risk [HR] 1.21, 95% confidence interval [CI] 1.04-1.39), any stroke (HR 1.32, 95% CI 1.15-1.51) and ipsilateral stroke (HR 1.26, 95% CI 1.02-1.55) in the CAS group were significantly higher than those in the CEA group;the risks of death (HR 1.06, 95% CI 0.95-1.18), disabling stroke (HR 1.23, 95% CI 0.95-1.60), non-ipsilateral stroke (HR 1.12,95% CI 0.81-1.55) and restenosis (HR 1.18,95% CI 0.91-1.52) were not significantly different between between the CAS group and the CEA group.Conclusions CAS and CEA are associated with similar risks of long-term death, disabling stroke, non-ipsilateral stroke and restenosis.The risks of long-term combined endpoint of stroke or death, any stroke and ipsilateral stroke significantly higher with CAS.These results suggest that CEA remains the treatment of choice for carotid stenosis.
