摘　　要：椎动脉发育不良是椎动脉的一种常见变异类型.关于椎动脉发育不良与后循环缺血性卒中的关系,目前尚无统一定论.现有的证据提示,椎动脉发育不良可能是后循环缺血性卒中的促发因素,尤其是在并存其他血管危险因素的情况下.文章阐述了椎动脉发育不良的流行病学、椎动脉发育不良患者后循环缺血性卒中的临床表现和影像学特点以及椎动脉发育不良引起后循环缺血性卒中的可能机制.Vertebral artery hypoplasia is a frequent variation type of vertebral arteries.At present,there is no unified theory about the relationship between vertebral artery hypoplasia and posterior circulation ischemic stroke.The available evidence suggests that vertebral artery hypoplasia may be a precipitating factor for posterior circulation ischemic stroke; particularly other vascular risk factors coexist.This article elaborates the epidemiology of vertebral artery hypoplasia,the clinical manifestation and imaging features of vertebral artery hypoplasia in patients with posterior circulation ischemic stroke,and the possible mechanism of vertebral artery hypoplasia caused posterior circulation ischemic stroke.
