Anatomical terminology

The anterior choroidal artery is a small but significant artery in the brain. It originates from the internal carotid artery and supplies blood to several critical structures within the brain.

Anatomy

The anterior choroidal artery typically arises from the internal carotid artery just after the posterior communicating artery branches off. It travels posteriorly and laterally, supplying blood to the choroid plexus of the lateral ventricle, the optic tract, the lateral geniculate nucleus, the internal capsule, the globus pallidus, and parts of the hippocampus.

Function

The primary function of the anterior choroidal artery is to provide oxygenated blood to the aforementioned brain structures. This is crucial for maintaining the health and functionality of these areas, which are involved in vision, motor control, and memory.

Clinical Significance

Occlusion or damage to the anterior choroidal artery can lead to significant neurological deficits. This can result in a variety of symptoms depending on the specific areas affected, including visual disturbances, motor weakness, and memory impairments. Such conditions are often evaluated using imaging techniques like MRI and CT scan.
