title: Treatment of a ruptured aneurysm involved in a double origin of the posterior inferior cerebellar artery.
abstract: Double origin of the posterior inferior cerebellar artery (DOPICA) is a rare anatomical variation, and can be associated with intracranial aneurysm formation. We describe a 66-year-old woman case of a ruptured aneurysm involved in a DOPICA. We performed aneurysmal coil embolization for the ruptured aneurysm involved in the cranial channel of DOPICA, but the aneurysm relapsed two months later. We subsequently performed internal trapping of the cranial channel because of well visualization of the distal flow by the balloon occlusion test. Endovascular trapping of a channel is one of the effective treatments of an aneurysm involved in DOPICA.
