摘　　要：目的:探讨MRA与DSA在后循环缺血患者椎基底动脉狭窄诊断中的价值。方法:对56例MRA提示椎基底动脉狭窄的后循环缺血患者进行DSA检查,观察两者影像学诊断的符合情况。结果:56例患者中MRA提示椎动脉异常中Ⅱ型异常与DSA符合率为80.6%,Ⅲ型异常两者符合率为21.4%,Ⅳ型异常两者符合率为75.0%,Ⅴ型、Ⅵ型异常两者符合率为0,基底动脉异常中Ⅱ型异常与DSA符合率为83.3%。结论:后循环缺血患者椎动脉MRA检查发现符合Ⅱ型、Ⅳ型异常及基底动脉MRA检查发现符合Ⅱ型异常严重者应考虑DSA检查,必要时行介入治疗,其他类型异常一般可不行DSA进一步检查。Objective：To discuss the value of MRA and DSA in diagnosis of vertebral-basilar artery stenosis in the patients of posterior circulation ischemia.Method：56 posterior circulation ischemia patients suggested vertebral-basilar artery stenosis in MRA were treated with DSA,and compared the conformability of MRA and DSA.Result：The conformability of MRA was 80.6%,21.4%,75%,0 and 0 in diagnosis of typeⅡ,typeⅢtypeⅣ,typeⅤand typeⅥvertebral artery abnormality,and 83.3%in diagnosis of typeⅡbasilar artery abnormality.Conclusion：Patients of posterior circulation ischemia should be treated with DSA if MRA suggests typeⅡandⅣvertebral artery stenosis,and typeⅡbasilar artery stenosis,other types can not be treated with DSA.
