Duplication of the internal carotid artery and segmental aplasia of the vertebral arteries.

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.
