Diagram

The carotid territory includes the retina and much of the anterior and lateral cerebral hemisphere. Key clinical problems referrable to ischemia in carotid territory involve occlusion of either the extracranial internal carotid artery (ICA) or its intracranial branches, including the ophthalmic artery, middle cerebral artery (MCA) or anterior cerebral artery (ACA).
