Anterior choroidal artery

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

StructureEdit

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

• choroid plexus of the lateral ventricle and third ventricle
• optic chiasm and optic tract
• internal capsule
• lateral geniculate body
• globus pallidus
• tail of the caudate nucleus
• hippocampus
• amygdala
• substantia nigra
• red nucleus
• crus cerebri

Clinical significanceEdit

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]
