Isolated occlusion of the common carotid artery (CCA) is a relatively uncommon lesion (0.5 to 5%). Most patients with occlusion of the CCA have concomitant lesions of the ipsilateral internal carotid artery (ICA) and external carotid artery (ECA), and ECA may occasionally preserve ICA patency by means of retrograde flow. We report the case of a symptomatic patient with occlusion of the CCA and patency of the ICA and ECA treated with subclavian-carotid bypass graft.
