Abstract

Background: Carotid artery stenting is used as an alternative to surgical endarterectomy. Objectives: To determine the outcomes of CAS in a retrospective cohort of patients. Methods: Between July 1999 and March 2003, 56 consecutive patiens with carotid artery stenosis who were considered ineligible for surgery were treated (45 males, 11 females, mean age 69). All underwent the procedure prior to the introduction of distal protective devices in Israel. Results: Intraprocedural complications included transient neurological findings in 5 patiens (8%), cerebrovascular accident in 2 (3%), hemodynamic changes in 11 (18%), and 4 procedural failures. Pnst-procedural complications included transient ischemic attack in 3 patiens and cardiovascular accident in 6 (10%). At 30 day follow-up, three patients (5%) remained with signs of CVA. Two patiens (3%) died during the post-procedural period and 16 (28%) during the 5 year follow-up, one due to recurrent CVA and the remainder to non-neurological causes. Five-year carotid Doppler follow-up was performed in 25 patients (45%), which revealed normal stent flow in 21 (84%), 50-60% restenosis in 3 (12%) and > 70% restenosis in one patient (4%). Conclusions: This study confirms that stent procedures are beneficial for symptomatic carofid stenosis in patients not eligible for surgery.
