Pericallosal artery
Last edit by Alaric Steinmetz on
The pericallosal artery is a branch of the anterior cerebral artery.
Anatomy
Course
The pericallosal artery runs in the cisterna laminae terminalis and then between the two hemispheres in the interhemispheric fissure above the corpus callosum. It runs around the genu of the corpus callosum and then posteriorly along the corpus callosum[^1].
Size
The average diameter of the pericallosal artery is approximately 2.9 mm on the right side and approximately 2.5 mm on the left side at the origin[^1].
Vascular Supply
The branches of the pericallosal artery are primarily responsible for supplying the corpus callosum, the cingulate gyrus and the medial surface of the parietal lobe[^1].
