A case of ruptured middle saccular aneurysm arising from basilar artery fenestration is reported. Defects of the medial wall at the junctures of the fenestrated segments explain the association between vertebrobasilar aneurysms and basilar artery fenestration. A 47 year-old woman had a perimesencephalic subarachnoid hemorrhage. Immediate angiography revealed a ventral vertebrobasilar aneurysm and an endovascular coil occlusion was performed. Embryological development, pathogenesis and therapeutic difficulties are discussed.
报告了一例起源于基底动脉开窗处的中囊状动脉瘤破裂病例。开窗节段交界处内侧壁的缺损解释了椎基底动脉瘤与基底动脉开窗之间的关联。一名47岁女性发生了中脑周围蛛网膜下腔出血。立即进行血管造影显示一个腹侧椎基底动脉瘤，并进行了血管内弹簧圈栓塞术。文中讨论了胚胎发育、发病机制及治疗难点。
