Abstract

Current Level I evidence demonstrates no benefit for carotid endarterectomy in symptomatic patients with <50% carotid stenoses. However, unstable plaque morphology is increasingly recognized in the genesis of ischemic cerebral events. New advanced imaging technology, such as contrast-enhanced magnetic resonance angiography and ultrasound imaging, are emerging as important adjuncts in the evaluation of this patient population. We present a case where both modalities were beneficial in identifying plaque instability manifested by intraplaque hemorrhage and neovascularization in a patient with recurrent cerebral ischemic events and hemodynamically insignificant carotid disease.
