We present a review of ultrasonic Doppler methods (duplex scanning) used in the noninvasive assessment of renal artery stenosis and hemodynamics. The clinically successful applications of ultrasonic Doppler methods to the noninvasive assessment of the peripheral and cerebral vasculatures have prompted investigators to apply these methods to the renal artery. Various Doppler criteria for the diagnosis of renal artery stenosis have given sensitivities and specificities that range from 31% to 91% and 88% to 100%, respectively. Furthermore, estimates of renal vascular flows and resistances can be made in echogenic subjects. The technical success rate of the method is operator dependent, consequently, reliable duplex scanning of the renal arteries may be limited to experienced ultrasound laboratories.
我们对用于肾动脉狭窄和血流动力学无创评估的超声多普勒方法(双功扫描)进行综述。超声多普勒方法在周围血管和脑血管无创评估中的临床成功应用促使研究人员将这些方法应用于肾动脉。诊断肾动脉狭窄的各种多普勒标准的敏感性和特异性分别为31%至91%和88%至100%。此外,在有回声的受试者中可以对肾血管流量和阻力进行估计。该方法的技术成功率取决于操作人员,因此,可靠的肾动脉双功扫描可能仅限于经验丰富的超声实验室。
