P Com–P1 Aneurysm Formation in a Patient with Bilateral Internal Carotid Occlusion^[*]

Summary

This study presents a rare case of subarachnoid hemorrhage (SAH) caused by an aneurysm formation on the posterior communicating artery (P Com), adjacent to the junction with the P1 branch in a patient with a long-lasting, bilateral occlusion of the internal carotid arteries (ICA). Furthermore, we discuss the incidence of aneurysm formation in idiopathic occlusion of the ICA.
