To assess the value of continuous-wave Doppler sonography for detection and exclusion of lesions in the vertebrobasilar system, the ultrasonic and angiographic findings were compared in a prospective study. Altogether, 200 vertebral arteries in 176 patients were evaluated by both methods. Insonation of the vertebral arteries was performed at the mastoid slope and at the origin of the vessel. Of 62 angiographically proven lesions, 45 were detected by ultrasound. Of 138 normal vertebral arteries, 129 were correctly diagnosed. Sensitivity for all lesions was 72.5%, and for hemodynamically relevant lesions it was 91%. Overall specificity was 93.5%. A positive predictive value of 83.3% and a negative predictive value of 88.4% for all lesions shown by angiography demonstrate the high reliability and accuracy of doppler ultrasound of the vertebrobasilar system.
为评估连续波多普勒超声检查在检测和排除椎基底动脉系统病变中的价值，在一项前瞻性研究中对超声和血管造影检查结果进行了比较。共有176例患者的200条椎动脉接受了两种方法的评估。在乳突斜坡和血管起始处对椎动脉进行了超声检查。在血管造影证实的62处病变中，45处通过超声检测到。在138条正常椎动脉中，129条被正确诊断。对所有病变的敏感性为72.5%，对血流动力学相关病变的敏感性为91%。总体特异性为93.5%。血管造影显示的所有病变的阳性预测值为83.3%，阴性预测值为88.4%，这表明椎基底动脉系统多普勒超声具有很高的可靠性和准确性。
