Abstract
The internal carotid artery mainly supplies the brain. As the internal carotid artery
contributes to the formation of the cerebral arterial circle, its variations are relevant
in imaging, interventional radiology, and surgery. Knowledge of these variations is
important for vascular anastomosis in free flap reconstruction and in arterial ligatures
for haemostasis. During a cadaveric cervical dissection, a duplicated left internal
carotid artery was incidentally observed in the carotid triangle of the neck. The
internal carotid branches were dissected up to their distribution to the brain. The
two branches of the left internal carotid artery penetrated into the base of the skull
by the carotid canal and the foramen magnum, respectively. With the right internal
carotid artery, they formed the cerebral arterial circle. The basilar artery was formed
by the branch of the left internal carotid artery entering the skull by the foramen
magnum. The right internal carotid artery and the two branches of the left internal
carotid gave rise to all of the arteries of the cerebral arterial circle. The vertebral
arteries did not contribute to its formation. This duplication of the internal carotid
arteries is rare, as the literature does not describe any case of vertebral artery
aplasia replaced by an internal carotid artery.
