Initial experience with cerebral protection devices to prevent embolization during carotid artery stenting.

Objective: Carotid artery stenting (CAS) for treatment of carotid stenosis has not received wide acceptance because of the availability of carotid endarterectomy (CEA) with its excellent results and because of the risk of embolic stroke associated with CAS. The feasibility and efficacy of cerebral protection devices that may prevent such embolic complications have yet to be shown. We report our initial results with CAS performed with cerebral protection.
