Abstract

Objectives: The purpose of this study was to conduct a meta-analysis to systematically compare the safety and efficacy of carotid endarterectomy and carotid artery stenting in contralateral carotid occlusion patients who needed reperfusion. Methods: This study retrieved potential academic articles comparing results between carotid endarterectomy and carotid artery stenting for patients with contralateral carotid occlusion from the MEDLINE database, the PubMed database the EMBASE database, and the Cochrane Library from January 1990 to May 2018. The reference articles for the identified studies were carefully reviewed to ensure that all available documents were represented in the study. Results: Four retrospective cohort study involving 6252 patients with contralateral carotid occlusion were included in our meta-analysis. During 30-day follow-up, there is significant difference in post-procedure mortality (odds ratio (OR) = 0.476, 95% confidence interval (CI) (0.306–0.740), P = 0.001); no significant differences are not found in post-procedure stroke (risk difference (RD) = 0.002, 95%CI (–0.007 to 0.011); P = 0.631), myocardial infarction (RD = 0.003, 95%CI (–0.002 to 0.008); P = 0.301), and transient cerebral ischemia (RD = 1.059, 95%CI (–0.188 to 5.964); P = 0.948). Conclusions: Carotid endarterectomy was associated with a lower incidence of mortality compared to carotid artery stenting for patients with contralateral carotid occlusion. Regarding stroke, myocardial infarction, and transient ischemic attack, there was no significant difference between the two groups. More randomized controlled trials and prospective cohorts are necessary to help further clarify the ideal approach for these patients.
