Overview

Carotid stenosis are asymptomatic if no hemispheric or retinal symptoms have appeared in the 6 months preceding the discovery of the stenosis. Asymptomatic carotid stenosis (ACS) accounts for about ¾ of all carotid lesions. The goal of treating carotid stenosis is to prevent a stroke. While carotid surgery is recommended in the elderly patients in cases of symptomatic carotid stenosis, that of ACS in patients over 75 years old, even when tight, remains subject to many controversies. Indeed, the debate, concerning the benefit to be expected from a surgical procedure or a possible angioplasty procedure, is not yet closed. The aim of our study, through a retrospective evaluation of the results of all consecutive carotid endarterectomy (CEA) and stenting in the participating center.
