      Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2)

      Carotid revascularization for primary prevention of stroke (CREST-2) is two independent multi-center, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1-to-1 ratio to endarterectomy versus no endarterectomy, and another will randomize patients in a 1-to-1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed. The purpose of this trial is to determine the best way to prevent strokes in people who have a high amount of blockage of their carotid artery but no stroke symptoms related to that blockage.
