Lateral Position of the External Carotid Artery: A Rare Variation to Be Recognized During Carotid Endarterectomy

Background External carotid artery (ECA) positioned laterally to the internal carotid artery (ICA) at the level of the common carotid artery (CCA) bifurcation is occasionally encountered during carotid endarterectomy (CEA). This study aimed to determine the frequency of this phenomenon and provide technical tips for performing CEA.
