Comparison of carotid artery stenting and carotid endarterectomy in patients with symptomatic carotid artery stenosis: A single center study

摘要

Introduction: Carotid artery stenting (CAS) is believed to be an alternative to carotid endarterectomy (CEA); however, recent studies have demonstrated an increase of complications with stenting that does not reflect our experience. We thus wanted to compare the periprocedural and 1-year follow-up outcomes of CAS with those of CEA among patients with symptomatic extracranial carotid stenosis in a population from eastern Turkey. Methods: The hospital records of all patients who underwent carotid artery revascularization were retrospectively reviewed. Patients were divided into two groups based on the type of carotid revascularization performed, namely CEA or CAS. Comparisons were made with respect to 30-day and 1-year outcomes of transient ischemic attack (TIA), myocardial infarction (MI), stroke, and all-cause death rates. Composite endpoints for both groups were also analyzed. Results: Thirty-two CEA and 33 CAS procedures were performed for symptomatic occlusive carotid disease. Baseline characteristics were similar between both groups except for the incidence of diabetes mellitus. No significant differences were found with respect to 30-day mortality, MI, and neurologic morbidity endpoints for CEA and CAS procedures. In the postprocedural 1-year follow-up, only TIA was observed to be significantly higher in the CAS group; the other endpoints did not differ significantly. One-year composite endpoints did not differ between both groups (log-rank P = 0.300). Conclusion: In our trial of patients with symptomatic carotid artery stenosis, no significant difference could be shown in periprocedural outcomes, postprocedural outcomes except TIA, and in composite endpoints between the CEA and CAS groups. CAS is a safe and efficacious alternative for the treatment of symptomatic carotid artery stenosis.
