摘　　要：报道８２例共１６３条肾动脉的彩色多普勒超声检查结果。其中，１８例可疑肾动脉狭窄的患者，肾脏病及甲状腺机能亢进症各１０例，高血压病１５例，健康自愿者２９名。经血管造影证实，肾动脉内径减少０％～４９％１９条，５０％～９９％１１条，闭塞５条。每例患者的肾动脉峰值流速（Ｖｐ）及其与腹主动脉峰值流速之比（ＲＡＲ）进行了测量。结果表示，对于≥５０％的肾动脉狭窄，Ｖｐ＞１８０ｃｍ／ｓ显示９０．９％的敏感性和９８．５％的特异性，ＲＡＲ＞２．０显示８１．８％的敏感性和９７．９％的特异性。肾动脉闭塞的诊断正确率为１００％。The renal arteries of 82 oases were studied with color Doppler folw imaging, including 18 with suspected renal artery stenosis,15 hypertension, 10 nephrosis, 10 hyperthyroidism patients and 29 healthy volunteers.There were 19 renal arteries with 0% to 49% stenosis, 11 with 50% to 99% stenosis and 5 occlusions demonstrated by angiography.The peak systolic velocity in the renal artery(Vp),and the ratio of the peak velocity in the renal artery to that in the abdominal aorta(RAR) were measured. In cases of significant renal artery stenosis(≥50% diameter reduction),Vp>180 cm/sshowed a 90.9% sensitivityand 98.5% specificity;RAR>2.0 showed a 81.8% sensitivity and 97.9% specificity.The diagnostic accurate rate of renal artery occlusion was 100%.
