Anatomy of the internal carotid artery
Subspecialty: Neuro-anatomy
Type: Clinical Summary
The supratentorial arterial complex — centered on the intradural, supraclinoid portion of the internal carotid artery (ICA) and its branches — forms the vascular supply to the cerebral hemispheres and the anterior circle of Willis; its anatomic relationships underlie the pathogenesis and operative management of intracranial aneurysms, skull‑base tumors, and other cerebrovascular disease. This review synthesizes detailed segmental anatomy of the ICA (C1–C4), the ICA’s major branches (including the ophthalmic, posterior communicating, and anterior choroidal arteries), perforating branch distribu…
