Results of carotid artery stenting with distal embolic protection with improved systems: Protected Carotid Artery Stenting in Patients at High Risk for Carotid Endarterectomy (PROTECT) trial

CAS outcomes in patients at high risk for CEA have improved from earlier carotid stent trials. With periprocedural rates of DSMI of 2.3%, death or stroke at 1.8%, and death or major stroke rate of 0.5%, PROTECT has the lowest rate of periprocedural complications among other comparable single-arm CAS trials in patients at high risk for CEA.
