椎动脉颅内段发育不良影像学评估及其与后循环缺血性卒中关系的研究进展

Research progress on imaging of intracranial vertebral artery hypoplasia and its relationship with posterior circulation ischemic stroke

椎动脉发育不良(VAH)与后循环缺血性卒中相关,但VAH与椎动脉动脉粥样硬化性狭窄在脑血管造影等影像学检查上较难鉴别。目前椎动脉颅内段发育不良尚无统一的诊断标准。作者从尸检、影像学检查等方面对椎动脉颅内段发育不良的定义及发生率进行了总结,并对其与后循环缺血性卒中的关系进行了综述,以期提高临床医师对椎动脉颅内段发育不良的认识。

Studies have shown that vertebral artery hypoplasia(VAH)is associated with posterior circulation ischemic stroke,but it is difficult to distinguish VAH from atherosclerotic stenosis in cerebrovascular angiography and other imaging examinations,and there is currently no unified diagnostic standard for intracranial VAH.The authors reviewed the definition and incidence of intracranial VAH from the aspects of autopsy and imaging,and summarized its relationship with posterior circulation ischemic stroke,in order to improve the clinicians′understanding of intracranial VAH.
