Abstract

Proximal posterior inferior cerebellar artery (PICA) aneurysms exhibit complex morphology, limiting endovascular treatment indications; microsurgical clipping is sometimes crucial. Far lateral craniotomy with condylar fossa drilling and harvesting the occipital artery (OA) for OA–PICA anastomosis is considered effective. We report a case of a ruptured proximal PICA aneurysm successfully treated using this strategy. As endovascular techniques expand, maintaining microsurgical proficiency is essential for effective management of proximal PICA aneurysms.
