Purpose: To evaluate the efficacy of carotid artery stent placement with embolic protection.
Materials and methods: During a 2-year period (May 2003 to April 2005), 232 patients underwent carotid artery stent placement with the Acculink RX stent-graft and an embolic protection device. There were 150 men (mean age,70 years; age range, 58-85 years) and 82 women (mean age, 76 years; age range, 56-82 years). One hundred sixty-five patients were symptomatic and 67 were asymptomatic. All patients were at high risk for carotid endarterectomy.
Results: The procedure was technically successful in 231 patients. The procedure was stopped in one patient due to asystole. In three patients, a cervical approach was necessary owing to aortic arch anatomy. During the procedure,11 patients (4.74%) experienced bradycardia and two developed a major stroke (0.86%). The mean follow-up was 30 months (range, 12-36 months). Four patients died. No stent occlusion was observed. During the late follow-up period(>30 days), two patients (0.86%) had minor strokes, three (1.29%) had nonfatal transient ischemic attacks, and seven(3.01%) had myocardial infarctions.
Conclusion: Carotid artery stent placement with cerebral protection by using the specific devices compares favorably to previously reported surgical results.
