A Randomized Trial of Carotid Artery Stenting With Balloon Guide Catheter
Starting soon · Not applicable
Conditions studied: Carotid Artery Stenosis
In brief
This prospective, multicenter, randomized controlled study enrolled patients undergoing carotid artery stenting (CAS) with cerebral embolic protection for carotid artery stenosis. They were randomly assigned to either a combination of proximal balloon occlusion, filter protection, intermediate catheter or filter protection alone. The study included 132 patients, and the primary endpoint was the number of new infarcts on cerebral diffusion-weighted imaging (DWI) within 48 hours (±24 hours) post-procedure.
