本文对１０６例临床确诊的椎－基底动脉系统短暂性脑缺血发作（ＶＢＴＬＡ）患者的ＣＴ、ＭＲＩ和临床资料进行了回顾性分析。结果表明，９％ＶＢＴＩＡ患者ＣＴ显示与症状相关的梗塞，１１．３％ＣＴ显示非相关梗塞，ＭＲＩ资料表明，高达２６．４％的ＶＢＴＩＡ显示相关梗塞，２４．６％显示非相关梗塞。在ＶＢＴＩＡ发作０～２４ｈ间，缺血发作时间长者发生相关梗塞的比例高。这些梗塞灶多数为小而深的病灶，大部分属于腔隙性梗塞的范围。
In this paper, 106 cases of clinically diagnosed vertebrobasilar system transient ischemic attack (VBTLA) in patients with CT, MRI and clinical data were analyzed retrospectively. The results showed that 9% of VBTIA patients showed CT-related infarcts and 11.3% of CTs showed non-related infarcts. MRI data showed that up to 26.4% of VBTIA showed related infarcts and 24.6% showed unrelated infarcts. 0 ~ 24h in the onset of VBTIA, the proportion of elderly patients with ischemic attack associated with high incidence of infarction. Most of these infarctions are small and deep lesions, most of which belong to the scope of lacunar infarction.
