Abstract

Background: The present multicenter retrospective study aimed to compare the outcome of carotid artery stenting (CAS) versus carotid endarterectomy (CEA) among Korean patients with symptomatic extracranial carotid stenosis. Methods: Between January 2008 and December 2011, 677 patients underwent either CAS (346, 51.1%) or CEA (331, 48.9%). The primary end point included the occurrence of major adverse cardiovascular events (MACEs), defined as fatal or nonfatal stroke and myocardial infarction, and all-cause mortality during the periprocedural period and within 4 years after CAS or CEA. Results: Although patients undergoing CAS and CEA did not differ significantly in MACE incidence within 4 years (15.3% vs. 11.5%, P = 0.14), CEA showed lower periprocedural MACE incidence than CAS with clinical significance (6.1% vs. 3.0%, P = 0.06). During the periprocedural period, the incidence of any stroke was significantly higher in patients undergoing CAS (5.5% vs. 2.4%, P = 0.04) but not the incidence of myocardial infarction (0.6% vs. 0.3%, P > 0.99). Kaplan–Meier survival analysis showed similar MACE-free (P = 0.16), stroke-free (P = 0.24), and overall survival (P = 0.25) rates in both groups. On subgroup analysis, patients older than 70 years undergoing CAS had a significantly higher incidence of MACE at 4 years (22.7% vs. 13.7%, P = 0.03). Conclusions: Although the risk of MACE did not differ significantly within 4 years in this Korean population undergoing CAS and CEA, there was a higher risk of stroke with CAS during the periprocedural period.
