椎基底动脉供血不足患者的椎动脉MRA表现

The manifestation of vertebral artery magnetic resonance angiograph in patients of vertebrobasilar arterial insufficiency

目的 探讨椎基底动脉供血不足患者核磁共振血管成像 (MRA)的表现及临床诊断价值。方法 97例患者中女性63例 ,男性34例。年龄34～79岁 ,平均50.78岁。分别进行椎动脉MRA及TCD检查。符合椎基底动脉供血不足诊断标准。结果 97例患者中椎动脉MRA异常61例(占62.88%) ,TCD异常83例(占85.56%)。结论 椎动脉本身退变因素导致椎基底动脉供血不足是一个主要因素。

Objective To explore the manifestation and clinic diagnostic value of vertebral artery magnetic resonance angiograph(MRA)in patients of vertebrobasilar arterial insufficiency. Methods 97patients(female63,male34,age34-79,average50.78)coincided with diagnostic standard of vertebrobasilar arterial insufficiency were selected and performed vertebral artery MRA and Transcraniodoppler(TCD). Results In97patients,vertebral artery MRA appeared abnormal in61patients(62.88%)and TCD appeared abnormal in83patients(85.56%) Conclusion vertebral artery itself degenerating factor was a main factor resulted in vertebrobasilar arterial insufficiency.
