Anterior choroidal artery
The anterior choroidal artery (Latin: arteria choroidea anterior) is a branch of the internal carotid artery. It supplies several important structures in the brain.
The anterior choroidal artery arises from the distal part of the internal carotid artery, distally from the origin of the posterior communicating artery. It passes posterolaterally above the medial part of the uncus, along the optic tract, curves laterally to reach the lateral side of the geniculate body. Further, the anterior choroidal artery enters the inferior horn of the lateral ventricle through the choroidal fissure and ends in the choroid plexus.
The anterior choroidal artery supplies the following brain regions: crus cerebri of the midbrain, lateral geniculate body, choroid plexus of the lateral ventricles and third ventricle, globus pallidus, caudate nucleus, amygdala, hypothalamus, red nucleus, substantia nigra, posterior limb of the internal capsule, optic tract, hippocampus, and the fimbria of the fornix.
