Abstract
Common carotid artery (CCA) occlusion is sometimes associated with collateral flow through carotid bulb that preserves patency of internal carotid artery (ICA). Usually ipsilateral external carotid artery (ECA) anastomotic branches supply the ICA. But in this case, we found the contralateral ECA role in collateralization of the ipsilateral ICA to CCA occlusion using color carotid duplex.
