Independent origins of the internal and external carotid arteries--a case report.
A case illustrating a congenital anomaly in the development of the left carotid artery is presented. The common carotid artery was found to be absent, with both internal and external carotid arteries arising separately from the aortic arch. This is a rare occurrence that is described angiographically and embryologically.
