我们评价超声超声多普勒测速仪对肾动脉狭窄无创诊断的准确性。多普勒血流动力学检查如发现下列四项血流动力学参数异常，即诊断肾动脉狭窄：(1)血流峰值速度大于100cm。(2)舒张期没有血流速度，(3)没有任何可检测到的血流速度表示闭塞，或(4)由于局灶血流速度紊乱导致的宽带多普勒频谱。根据这些标准，对26例接受标准或数字减影血管造影的患者（52条动脉）是否存在肾动脉狭窄进行盲法评估。与动脉造影（直径缩小大于或等于50%）相比，多普勒法的灵敏度为89%，特异性为73%。这种无创方法可用于选择肾动脉狭窄的患者进行影像学评估和这些患者的长期随访。此外，超声多普勒测速仪可能具有评估肾动脉狭窄血流动力学后果的独特能力。
We evaluated the diagnostic accuracy of ultrasonic echo-Doppler velocimetry for the noninvasive diagnosis of renal artery stenosis. Renal artery stenosis was diagnosed if one or more of the following four abnormal hemodynamic parameters were found by Doppler velocimetry: (1) peak blood velocity greater than 100 cm . sec-1 in a focal area along the length of a renal artery, (2) absence of blood velocity during diastole, (3) absence of any detectable blood velocity denoting occlusion, or (4) broad-band Doppler frequency spectra due to focal blood velocity disturbances. With these criteria, the presence or absence of renal artery stenosis was blindly evaluated in 26 patients (52 arteries) who underwent standard or digital subtraction angiography. Compared to arteriography (reduction in diameter greater than or equal to 50%), the sensitivity of Doppler method was 89%, while its specificity was 73%. This noninvasive method may be useful in selecting patients for radiographic evaluation of renal artery stenosis and in the long term follow-up of these patients. Furthermore, echo-Doppler velocimetry may have the unique capability of assessing the hemodynamic consequences of renal artery stenosis.
