The anterior choroidal artery: An anatomical study of its area of distribution

Abstract

The morphology and the structures supplied by the extraventricular segment of the anterior choroidal artery was studied in 22 human brains. The pertinent arterial sections were injected with a gelatin‐india ink mixture and the brains serially sectioned and cleared after formalin fixation. The area of distribution of the anterior choroidal artery varied widely.There is good supply to the globus pallidus, the posterior and retrolenticular portions of the internal capsule, the cerebral peduncle, the optic tract and the lateral geniculate body. A lesser supply is furnished to the genu of the internal capsule, thalamus, hypothalamus, subthalamus, and amygdala.
