The anterior cerebral artery: I. Anatomo-radiological study of its cortical territories.

A comparative study and angiographic analysis of 24 brains were performed using selective radiopaque injections of the anterior cerebral artery. The arterial branches were projected on a model brain, using a bicommissural system of coordinates and a stereotaxic method as an encephalometric system of reference. Eleven constant cortical branches of the artery were demonstrated and their vascular territories demarcated.
