Abstract :Persistence of fetal communications between the carotid and vertebrobasilar systems is uncommon. Persistent proatlantal artery is an anastomosis between the carotid and vertebrobasilar systems, typically classified as Type I and II. In this case report, 600 angiographies are examined retrospectively and two persistent proatlantal arteries were observed - one with Type I insert ignore into journalissuearticles values(0.16%); and the other with Type II insert ignore into journalissuearticles values(0.16%); proatlantal artery. Existence of these arteries are associated with intracranial vascular anomalies, especially aneurysms. In both of our cases, an aneurysm was detected in the middle cerebral artery. Precise knowledge of these anastomoses is essential for intracranial operations and catheterizations performed in this region.
