Thirty-day outcomes of carotid endarterectomy in the elderly: A 17-year single-center study

Abstract

IntroductionCarotid endarterectomy (CEA) has been supported as a durable procedure for treating patients with carotid artery stenosis by many randomized controlled trials (RCTs). The aim of this study was to evaluate the 30-day outcomes and risk factors for CEA in elderly patients with a retrospective single-center study. MethodsOur study sample consisted of patients from 2001 to 2017 CEA-targeted Xuanwu Hospital, Capital Medical University data set. The primary outcome was 30-day postoperative incidence of major adverse clinical events (MACEs; death, myocardial infarction (MI) and ipsilateral stroke). Univariable and multivariable analyses were performed to identify high-risk patients and procedural characteristics associated with MACEs. ResultsA total of 348 elderly patients undergoing CEA for carotid artery stenosis were identified and analyzed. The incidence of postoperative MACEs was 4.6% (16 cases, included 1 death, 14 S, and 1 MI respectively) for elderly patients. Univariate analysis indicated symptomatic lesion (81.3% vs 55.7%, p = 0.044), diabetes mellitus (56.3% vs 26.8%, p = 0.011) and DBP (85.56 ± 11.26 mmHg vs 76.53 ± 9.51 mmHg, p < 0.001) were statistically significant with MACEs. On multivariable analysis, independent predictors of MACEs included diabetes mellitus (DM) (OR = 2.882; 95% CI = 1.005–8.266; P = 0.049) and higher diastolic blood pressure (DBP) (OR = 1.079; 95% CI = 1.025–1.136; P = 0.004). Symptomatic lesion was not an independent risk factor (OR = 2.805; 95% CI = 0.759–10.361; P = 0.122). ConclusionsAccording to our single-center experience, CEA could be safely performed in elderly patients. Risk factors identified for MACEs in this special group patients were DM and higher DBP.
