Anatomical terminology

The anterior choroidal artery originates from the internal carotid artery, though it also rarely arises from the middle cerebral artery.[1]

Structure[edit]

The anterior choroidal artery serves structures in the telencephalon, diencephalon, and mesencephalon:[2]

Clinical significance[edit]

The full extent of the damage caused by occlusion of the anterior choroidal artery is not known. However, studies[which?] show that the interruption of blood flow from this vessel can result in hemiplegia on the contralateral (opposite) side of the body, contralateral hemi-hypoesthesia, and homonymous hemianopsia. These symptoms are thought to arise from ischemic damage to the posterior limb of the internal capsule, thalamus, and optic chiasm/optic tract. However, the posterior limb of the internal capsule also receives lenticulostriate arteries from the Middle Cerebral Artery, thus creating partially redundant supply.[3]
