title: Iatrogenic traumatic intracranial aneurysm after endoscopic sinus surgery.
abstract: Iatrogenic traumatic intracranial aneurysms are rare, but their clinical impact is significant secondary to their risk of intracranial hemorrhage and in their frequent complexity in management. We report an adult patient with a history of chronic sinusitis who, while undergoing elective endoscopic polypectomy, suffered an iatrogenic injury to an A2 segment branch of the left anterior cerebral artery, resulting in a pseudoaneurysm. Management included endovascular coiling and a bicoronal craniotomy approach, using a split-thickness cranial graft and abdominal fat graft to repair the associated left cribriform plate defect.
