Carotid Endarterectomy for Atherosclerotic Stenosis Associated with Non-bifurcating Cervical Carotid Artery: A Case Report.

We report a case of a 79-year-old man presenting with left cervical carotid artery stenosis associated with non-bifurcating cervical carotid artery, a very rare congenital anatomical variation supplying different branches of the external carotid artery directly from a common trunk without a bifurcation. We performed carotid endarterectomy for this symptomatic carotid artery atherosclerotic stenosis. Here, we discuss the treatment strategy, arteriotomy, route for flush out, and usage of a shunt devise system for this characteristic morphology. In addition, the embryological mechanism for developing this rare anatomical variation is discussed.
