Selective Occipital Artery-Posterior Cerebral Artery Bypass Guided by Fusion Imaging and Short-Segment Parent Artery Occlusion for a Partially Thrombosed Posterior Cerebral Artery Aneurysm: A Case Report

Year: 2025

Type: article

Abstract: Introduction: Partially thrombosed aneurysms of the posterior cerebral artery (PCA), especially in the P2 segment, pose considerable treatment challenges owing to complex anatomy and ischemic risk. Case Presentation: We report a 49-year-old woman with a partially thrombosed dissecting P2 aneurysm treated using selective occipital artery-PCA bypass guided by digital subtraction angiography-magnetic resonance fusion imaging, followed by endovascular occlusion using Target Tetra coils. Postoperative imaging confirmed bypass patency and complete aneurysm obliteration without infarction or neurological deficit. Conclusion: We highlight a feasible treatment strategy for complex PCA aneurysms, emphasizing the importance of fusion imaging and targeted embolization in minimizing complications and preserving function.
