The objective of the study was to describe immediate and long-term results of carotid endarterectomy (CEA) versus carotid stenting (CAS) with embolic protection in patients with severe carotid artery stenosis in clinical practice. Materials and Methods: This is a retrospective cohort study, conducted between 2009 and 2017. During the analyzed period, 2132 operations (2006 patients) were performed: 1215 (57%) CEA and 917 (43%) CAS. 278 patients (13.8% of 2006) were not contactable during the follow-up period (>30 days) leaving 1791 cases (1728 patients) for inclusion in the analysis. Propensity score matching was used to compare the treatment results of groups (561 cases were matched out of 1791). The results of 615 CEA (316 eversion, 299 “classic” with patch) and 615 CAS (using a variety of carotid stents) were compared. Results: In the asymptomatic subgroup (n = 455), the 30-day rate of stroke was not significantly different between the CEA group and the CAS group (1.5% versus 2.4%, P =.48). The 5-year rate of stroke was not significantly higher for CAS than for CEA (4.6% versus 3.3%, P =.3). In the symptomatic subgroup (n = 160), the 30-day rate of stroke was significantly higher in the CAS group than in the CEA group (7.5% versus 2.5%, P =.04). The 5-year rate of stroke was 13% for CAS and 8.7% for CEA (P =.2). Conclusions: In the symptomatic subgroup, the 30-day rate of stroke was significantly higher in the CAS group than in the CEA group, therefore the use of CAS for symptomatic patients in routine practice should be limited. Our study demonstrates that the rates of stroke and survival after CEA and CAS in patients aged 80 years or younger with asymptomatic or symptomatic severe carotid stenosis did not differ significantly over a period of 5 years.
