Abstract:
Basilar artery pseudoaneurysm (BAPA) is an extremely rare yet life-threatening intracranial vascular lesion, characterized by insidious clinical onset and a remarkably high mortality risk upon rupture. In this case report, we describe a patient who was admitted to our department with spontaneous subarachnoid hemorrhage (SAH). Emergency digital subtraction angiography performed on admission revealed no vascular anomalies. One month after SAH onset, a comprehensive multimodal imaging evaluation ultimately confirmed the diagnosis of BAPA. Given the technical challenges in conventional management for this specific case, Traxcess-14 microguidewire-assisted endovascular electrocoagulation was performed as a last-resort therapy. Finally, follow-up imaging at 6 months demonstrated complete resolution of BAPA. Thus, we propose that Traxcess-14 microguidewire-assisted endovascular electrocoagulation may serve as a potential salvage treatment for highly selective BAPA cases in which conventional therapeutic approaches are unfeasible or have failed.
