Coil Embolization of Two Flow-Related Aneurysms in P1 Segment of the Posterior Cerebral Artery in a Patient with Occlusion of the Ipsilateral Internal Carotid Artery

Abstract

Aneurysms of the posterior cerebral artery (PCA) are uncommon (about 1% of all intracranial aneurysms) and their neurosurgical treatment is associated with high operative risk. We report on two saccular aneurysms of the P1 segment of the right PCA, combined with occlusion of the C1 segment of the internal carotid artery (ICA) detected during routine diagnostic studies in a 58-year-old patient with slight sensory loss in the left extremities. The aneurysms were embolized during two consecutive sessions, without subsequent complications. Endovascular intervention is an efficient method in the treatment of multiple aneurysms in the P1 segment of the PCA.
