PURPOSE: Some patients with severe carotid stenosis have anatomical or clinical comorbidities that place them at high risk for carotid endarterectomy (CEA). The early and late outcomes after carotid artery stenting (CAS) were evaluated in patients at high risk for CEA.
METHODS: Between 2002 and 2009, 186 patients were enrolled in a high-risk CAS institutional registry. The primary outcome was major adverse cardiac and cerberovascular events (MACCEs) at 30 days, including death, stroke, and myocardial infarction. Secondary outcomes were technical, procedural, and clinical success; nonstroke neurological events; and death and ipsilateral stroke at 5 years.
RESULTS: Twenty-five patients (13.2%) were symptomatic. Thirty day MACCE occurred in 2.6%, including death in 1 (0.5%), stroke in 3 (1.6%), and myocardial infraction in 1 (0.5%) patient. Strokes were nonfatal in 3 (1.6%), major in 2 (1.1%), and minor in 1 (0.5%) patients. Other neurological events included transient ischemic attack in 9 (4.7%) and retinal artery occlusion in 2 (1.1%) patients. After stroke, 2 patients had complete resolution of neurological deficit within 30 days, and 1 patient had improvement in neurological deficit. By Kaplan--Meier analysis, all-cause mortality was 47.5% and ipsilateral stroke was 4.5% at 5 years.
CONCLUSIONS: In patients who are high risk for CEA, CAS can be performed with low MACCE at 30 days and ipsilateral stroke at 5 years. However, nearly half of these patients die within 5 years from causes unrelated to stroke.
