Comparison between outcomes of carotid endarterectomy and carotid artery stenting in treating elderly patients

Abstract

Objective To review the clinical data of elderly patients treated by carotid endarterectomy (CEA) and carotid artery stenting (CAS), and analyze the safety of two kinds of surgery.  Methods A total of 691 patients with carotid artery stenosis underwent CEA (121 cases) and CAS (570 cases) respectively. The risk factors, clinical symptoms and postoperative complications in 2 groups of patients were analyzed, and the safety of two kinds of surgery were assessed.  Results After 30 d of operation, no significant difference was found between 2 groups in death rate (0.83% vs 1.05%, P = 1.000), stroke rate (4.13% vs 1.93% , P = 0.258) or myocardial infarction rate (0.83% vs 0, P = 0.175). Heart complications and cranial nerve injury rate in CEA group was significantly higher than that in CAS group (8.26% vs 1.05%, P = 0.000; 4.96% vs 0, P = 0.000), while sinus bradycardia or hypotension rate in CEA group was significantly lower than that in CAS group (0 vs 7.54%, P = 0.002). Conclusions Both CEA and CAS are safe for the elderly patients. However, the conditions of elderly patients should be evaluated before operation in order to reduce occurence of complications after operation.
