The authors report an unusual surgical treatment for an aneurysm on the left peripheral posterior inferior cerebellar artery (PICA). The computed tomographic scan showed subarachnoid haemorrhage and a haematoma in the left cerebellar region close to the fourth ventricle. The 3D CT angiography demonstrated an aneurysm on the left peripheral PICA which was confirmed on four-vessel angiography. The aneurysm was approached through a posterior suboccipital craniotomy and the PICA was reconstructed with multiple clips. The literature concerning peripheral PICA aneurysms and their treatment is reviewed and discussed.
作者报告了一例对左侧小脑后下动脉（PICA）外周动脉瘤的特殊手术治疗。计算机断层扫描显示蛛网膜下腔出血以及左侧小脑区域靠近第四脑室处有血肿。三维CT血管造影显示左侧PICA外周有一个动脉瘤，四血管造影证实了这一点。通过枕下后开颅术暴露动脉瘤，并用多个夹子重建PICA。对有关外周PICA动脉瘤及其治疗的文献进行了回顾和讨论。
