While revascularization via carotid endarterectomy (CEA) or carotid artery stenting (CAS) provides comparable long-term protection against fatal or disabling stroke, intensive medical management (BMT) has significantly reduced the incidence of microemboli and cardiovascular events, potentially narrowing the absolute benefit of prophylactic intervention.
