Carotid artery stenting in surgical high-risk patients
Abstract
Recent studies have shown that carotid artery angioplasty and stenting may offer a viable alternative for symptomatic and asymptomatic patients with carotid artery stenosis, especially in high-risk patients. We report the results of a prospective single-center registry designed to evaluate the feasibility and safety of carotid artery angioplasty and stenting with and without distal protection devices in high-risk patients. A total of 116 consecutive patients underwent 126 procedures and 127 stents were deployed successfully in 130 lesions. The majority of patients (63%) had restenosis after a prior carotid endarterectomy; 31% were considered to be ineligible for carotid endarterectomy by both the vascular surgeons and the interventional cardiologist and 9% were considered ineligible for surgery due to hostile neck anatomy. Periprocedural and follow-up evaluation included a thorough independent clinical and neurological assessment. Distal embolic protection devices were used in 44% of all cases. Procedural success was achieved in 122 procedures (97%). The overall rate of in-hospital major adverse cerebrovascular events (death, stroke, and myocardial infarction) was 2.6%. Event rates in patients with prior carotid endarterectomy ...Continue Reading
