摘　　要：目的：探讨CTA对小脑后下动脉（ PICA）动脉瘤的诊断价值。方法对2例PICA动脉瘤患者的临床资料进行回顾性分析。结果2例患者为老年，急性发病，经CT确诊蛛网膜下腔出血，发病后3 h内初次CTA检查均为阴性结果。经防止脑血管痉挛、增高血容量、保护脑细胞等治疗3～7 d后，病情好转1例，无效1例。再次行CTA检查发现PICA动脉瘤3个，其中1例患者为左侧PICA 2个动脉瘤合并脑积水，另1例患者左侧PICA有1个动脉瘤。2例患者的PICA动脉瘤均获得良好的影像信息。结论 CTA可作为PI-CA动脉瘤首选的检查方法，能提供其全面的影像资料。对首次CTA检查阴性者，经短期治疗后进行CTA复查仍为理想的选择。Objective To explore the diagnosis value of CTA on posterior inferior cerebellar artery （ PICA ） aneurysm.Methods The clinical data of 2 patients with PICA aneurysms were analyzed retrospectively .Results Two patients were elderly,acute onset,CT confirmed subarachnoid hemorrhage ,CTA of the first time were negative within 3 h after the onset .After the treatments of preventing cerebral vasospasm , increasing blood volume , protecting brain cells and etc for 3-7 d, one case improved ,one case were invalid .Given CTA examination again then found 3 aneurysms, one case with 2 aneurysms located on the left side of the PICA , accompanying with hydrocephalus ,and the other case with 1 aneurysm located on the left side of the PICA .Two patients obtained a good image evaluation and rich information .Conclusions In view of the particularity of the PICA aneurysms , CTA can be used as the preferred method of examination , which can provide comprehensive imaging data .When CTA examination of the first time is negative , giving CTA again remains an ideal choice after short-term treatment .
