Abstract
INTRODUCTION: This is a retrospective analysis of the results of carotid endarterectomy (CEA) in different age groups. METHODS: This cohort, comparative, retrospective, open-label study for the period from 2008 to 2020 included 7248 patients with hemodynamically significant stenoses of the internal carotid artery (ICA), who underwent CEA. According to the classification of the World Health Organization, patients were divided into groups depending on age: up to 44 years-young age (n = 84); 45-60 years-middle age (n = 1635); 61-75-elderly age (n = 4817); over 75 years-senile age (n = 712). RESULTS: In terms of the frequency of hospital complications, the group of patients over 75 years of age experienced the largest number of cardiovascular events. One year after surgery, there were no significant differences in the incidence of complications between groups: death (group 1, 1.2%; group 2, 0.5%; group 3, 0.4%; group 4, 1%; p = 0.14), myocardial infarction (group 1, 1.2%; group 2, 0.3%; group 3, 0.14%; group 4, 0.3%; p = 0.12), stroke (group 1, 0%; group 2, 0.3%; group 3, 0.1%; group 4, 0.4%; p = 0.32). CONCLUSION: The largest number of adverse cardiovascular events after CEA are observed among patients over 75 years of age, which is due to the high frequency of multivessel coronary lesions, atrial fibrillation, and the severity of the comorbidities. One year after surgery, there were no significant differences in the incidence of complications between groups.
