Posterior Choroidal Artery

The Posterior Choroidal Artery is a branch of the Posterior Cerebral Artery that supplies the choroid plexus of the third ventricle and the lateral ventricle in the human brain.

Structure

The posterior choroidal artery arises from the Posterior Cerebral Artery and courses anteriorly and medially to reach the choroid plexus. It gives off several branches that supply the thalamus, hippocampus, and fornix.

Function

The primary function of the posterior choroidal artery is to supply blood to the choroid plexus of the third and lateral ventricles. The choroid plexus is responsible for the production of cerebrospinal fluid, which is crucial for the protection and nourishment of the brain.

Clinical significance

Damage or blockage of the posterior choroidal artery can lead to stroke or choroidal artery syndrome, which can cause a variety of neurological symptoms including memory loss, confusion, and visual disturbances.
