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.
摘要
小脑后下动脉双起源（DOPICA）是一种罕见的解剖变异，可能与颅内动脉瘤形成有关。我们描述了一例66岁女性患者，其DOPICA相关的动脉瘤破裂。我们对DOPICA颅段破裂的动脉瘤进行了动脉瘤弹簧圈栓塞，但动脉瘤在两个月后复发。由于球囊闭塞试验能清晰显示远端血流，我们随后对颅段进行了内闭塞术。血管内闭塞血管通道是治疗DOPICA相关动脉瘤的有效方法之一。
