Carotid endarterectomy for asymptomatic carotid stenosis.

Abstract

BACKGROUND: Whilst carotid endarterectomy (CEA) is of proven benefit in recently symptomatic patients with severe carotid stenosis, the role of carotid endarterectomy in preventing stroke in patients with asymptomatic carotid stenosis remains uncertain.
