Carotid artery stenting with distal filter protection: single-center experience in high-surgical-risk patients

Abstract

Carotid artery stenting (CAS) is an efficient alternative procedure for the treatment of high-surgical-risk patients with symptomatic and asymptomatic carotid stenosis. The use of cerebral protection systems might decrease procedural risk of stroke and death. We report our initial experience with protected carotid stenting in high-risk patients with severe carotid artery disease. From January 2006 until July 2008 we routinely performed CAS using a distal filter protection device in 65 consecutive high-surgical-risk patients with 72 high-grade carotid stenoses. Technical success rate was 97.2%. Neurologic periprocedural complications included two transient ischemic attacks and one major stroke. Three filter-related complications were managed without negative results to the patients. The overall in-hospital and 30-days MACE rate was 1.5%, 3.6% in symptomatic patients and 0% in asymptomatic patients. In our series of high-risk patients, CAS with the use of a distal filter protection system was safe and effective with a low incidence of periprocedural complications.
