目的探讨应用64排CT观测的后循环血管形态改变与后循环区域内梗死发生的关联性。方法回顾分析86例后循环梗死患者的MRI与CTA检查资料。结果86例患者总异常率达94%，其中基底动脉扭曲为66%，基底动脉局限性狭窄为43%；椎动脉扭曲为72%，椎动脉局限性狭窄为24%。结论除椎动脉、基底动脉狭窄外，椎动脉、基底动脉扭曲、纤细也是后循环缺血事件发生的主要诱因，特别是直角扭曲。CTA能有效显示后循环动脉三维图像，结合MRI对后循环血管形态改变的判定具有十分重要的临床价值。

Objective To investigate the correlation between the vascular morphological changes and the Ischemic Stroke of Posterior Circulation with 64-slice CT. Methods Eighty-six infarction patients of Posterior Circulation were studied retrospectively about MRI and CTA data. Results The total abnormality rate was 94% in 86 patients. The abnormality rate of distorted basilar artery was 66%,the limitations of narrowed basilar artery was 43%;distorted vertebral artery was 72%,the limitations of narrowed vertebral artery was 24%. Conclusion Not only narrowed vertebral artery and basilar artery,but also distorted and slender artery are important incentive in posterior circulation ischemic events,especially right-angle distortions.CTA and MRI examination can display the posterior circulation artery in three-dimensional image. They play an important role in the decision of morphological changes.
