Long-term follow-up of patients after carotid stenting with or without distal protective device in a single tertiary medical center

Abstract

Objective: To evaluate the immediate and long-term clinical outcomes after carotid artery stenting (CAS) with and without protection devices (PDs), compared with carotid endarterectomy (CEA).

Methods: A total of 116 patients with symptomatic carotid stenosis underwent CAS; 56 patients (48.3%) underwent CAS-PD; and 137 patients underwent CEA.

Results: There were more ipsilateral transient ischemic attacks (TIAs) in the CEA group than in CAS-PD and CAS + PD (4 [3%] vs 1 [1.6%] and 0 respectively, P = 0.02). In the CAS-PD group there were more vertebrobasilar TIAs, ipsi- and contralateral strokes, myocardial infarctions, and death rates in the 30-day postprocedural period. After 8-year follow-up, there were 18 (30%) death cases in the CAS-PD group, 10 death cases (17%) in the CAS + PD patients, and 15 death cases (11%) in the CEA group of patients (P = .02).

Conclusion: Our data show that CAS + PD was associated with lower rate of vascular complications and mortality compared with CAS-PD and CEA.
