Interventional management of asymptomatic extracranial carotid stenosis

Abstract

Carotid artery stenosis is a major risk factor for stroke and transient ischemic attack. Although carotid endarterectomy is the established gold standard for carotid revascularization, carotid artery angioplasty and stenting (CAS)-proven by large randomized clinical trials and rigorous registries and supported by improving stent designs, embolic protection, and increasing neurointerventionalist experience-is developing into a safer and more efficacious method of stroke prevention. Today, protected CAS is approved for symptomatic and asymptomatic patients with severe carotid stenosis with high surgical risk. We reviewed recently published data regarding new developments in the use of protected CAS, particularly in patients with carotid stenosis who are either asymptomatic or at low surgical risk. © 2010 Springer Science+Business Media, LLC.
