Continuous-wave Doppler and angiography of the vertebro-basilar system were used in 38 patients with vertebro-basilar transient ischemic attacks. 63 vertebral arteries were studied. Among 47 normal Doppler parameters, 46 were confirmed by angiography. The sonographic diagnostic procedure showed a very high negative predictive value (97.87%), while the positive predictive value was relatively low (56.25%). Data from literature were reviewed. The authors suggest that when Doppler of vertebral arteries is negative, there is a very low probability that a follow-up angiography will reveal pathologic conditions calling for a surgical approach.
对38例椎基底动脉短暂性脑缺血发作患者使用了椎基底动脉系统的连续波多普勒和血管造影检查。共研究了63条椎动脉。在47项正常多普勒参数中，46项经血管造影证实。超声诊断程序显示出非常高的阴性预测值（97.87%），而阳性预测值相对较低（56.25%）。回顾了文献数据。作者认为，当椎动脉多普勒检查结果为阴性时，后续血管造影显示需要手术治疗的病理状况的可能性非常低。
