Artery: Anterior choroidal artery

Latin	arteria choroidea anterior
Gray's	subject #147 574
Source	internal carotid artery
Dorlands/Elsevier	a_61/12153853

The anterior choroidal artery originates from the internal carotid artery, though it will rarely arise from the middle cerebral artery.

Structures supplied

The anterior choroidal artery serves many structures in the cerebrum:

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

Disorders

More investigation is required to determine the full extent of the damage caused by occlusion of this artery.

However, studies do show that interruption of this vessel's blood flow can result in hemiplegia on the opposite side of the body (contralateral), contralateral hemihypesthesia, and homonymous hemianopia.

These symptoms are thought to arise from ischemic damage to the posterior limb of the internal capsule.
