Quick Facts

The pericallosal artery is one of the two terminal branches of the anterior cerebral artery, the other being the callosomarginal artery. It commences near the genu of the corpus callosum, and then travels along the superior surface of the corpus callosum. Its path parallels that of the callosomarginal artery.

Along its course, the pericallosal artery gives off precuneal and parieto-occipital branches.

Overall, the pericallosal artery and its branches provide an arterial supply to the corpus callosum, and the inferior part of the medial surface of the cerebral hemisphere.

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
