Abstract
Carotid artery angioplasty and carotid artery stenting (CAS) offer a viable alternative to carotid endarterectomy for symptomatic and asymptomatic patients; however, the complication rates associated with CAS may be higher than previously documented. We evaluated the safety and efficacy of CAS in high surgical risk patients in a single neurovascular center retrospective review. An institutional review board-approved retrospective review of the clinical variables and treatment outcomes of 101 consecutive patients (109 stents) from July 2001 to March 2007 with carotid stenosis were analyzed. Both symptomatic and asymptomatic stenoses were studied in high surgical risk patients as defined by the SAPPHIRE (Stenting and Angioplasty with Protection in Patients at High-Risk for Endarterectomy) trial. Specifically, those patients with clinically significant cardiac disease (congestive heart failure, abnormal stress test, or need for open-heart surgery), severe pulmonary disease, contralateral carotid occlusion, contralateral laryngeal nerve palsy, recurrent stenosis after carotid endarterectomy, previous radical neck surgery, or radiation therapy to the neck, and an age older than 80. Seventy-four percent of the patients were symptomat...Continue Reading
