Results and complications of carotid endarterectomy in a hospital from Madrid, Spain.

Abstract

Objective\nTo study the incidence of cerebrovascular (transient ischemic attacks and stroke) and myocardial events (myocardial infarction) as well as early survival related to carotid endarterectomy. Our secondary aim is to establish possible risk factors associated with complications.\n\n\nMethod\nRetrospective observational case-control study within a cohort. All patients who underwent carotid endarterectomy by the angiology and vascular surgery service at the Hospital Universitario La Paz, in Madrid (Spain), in the period between January 2011 and December 2017 were included. Chi square was used to calculate differences. Kaplan-Meier and Cox regression was used for the survival analysis and patency.\n\n\nResults\n111 procedures were performed on 108 patients, 95 (87,9%) male with an average age of 68.5 ± 8.75. The mean time of follow-up was 2.9 years. There was no 30-day post-surgical mortality, with a 30-day postoperative cerebral vascular event rate of 2.7%. Statistically significant correlation was found between the presence of 30-day postoperative cerebral vascular event and primary closure (p = 0.005) as well as between the smoking habit and 30-day postoperative myocardial infarction (p = 0.036) and restenosis (p = 0.008). In mid-term follow-up, the event rate for cerebral vascular events and myocardial infarction was 1.8%.\n\n\nConclusion\ncarotid endarterectomy is the procedure of choice in carotid stenosis. The low rates of perioperative mortality, morbidity and complications have been demonstrated.
