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.
期刊介绍：
This new peer-reviewed online-only journal publishes original case reports covering the entire spectrum of neurology. Clinicians and researchers are given a tool to disseminate their personal experience to a wider public as well as to review interesting cases encountered by colleagues all over the world. To complement the contributions supplementary material is welcomed. The reports are searchable according to the key words supplied by the authors; it will thus be possible to search across the entire growing collection of case reports with universally used terms, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
