肾动脉纤维肌性发育不良是高血压的众所周知的原因，其存在通过其典型的动脉造影表现得到证实。这些病变的功能意义通常很难确定，特别是当双侧肾动脉都受累时。双面扫描已被证明可以准确地检测肾动脉狭窄并估计狭窄程度。为了测试干预后的双重扫描结果是否与临床结果相关，我们回顾了对九名接受血管成形术或手术治疗的肾动脉纤维肌性发育不良患者的研究。总共治疗了 18 条动脉。从血压和抗高血压药物的降低程度来看，18 种治疗中有 14 种是成功的。有四例治疗失败。对于那些临床改善的患者，肾动脉的血流动力学参数也有所改善。在治疗失败的患者中，从狭窄部位记录的速度在干预后没有改善。因此，双重扫描和临床结果似乎可以用来记录治疗后（无论是血管成形术还是手术）未能改善的基础。 （瓦斯克外科杂志 1992；15：604–11。）
Renal artery fibromuscular dysplasia is a well-known cause of hypertension whose presence is confirmed by its typical arteriographic appearance. The functional significance of these lesions is often difficult to determine, particularly when both renal arteries are involved. Duplex scanning has been shown to be accurate for the detection of renal artery stenosis and estimation of the degree of narrowing. To test whether duplex scanning results after intervention correlate with clinical outcome, we reviewed the studies on nine patients with renal artery fibromuscular dysplasia who had been treated by either angioplasty or surgery. A total of 18 arteries were treated. Fourteen of the 18 treatments were successful as measured by a reduction in blood pressure and antihypertensive drugs. In four instances treatment was unsuccessful. For those patients who had clinical improvement, the hemodynamic parameters from the renal artery also improved. In the patients for whom treatment failed, the velocities recorded from the site of narrowing did not improve after intervention. Thus it appears that duplex scanning along with the clinical results may be used to document the basis for failing to improve after treatment be it angioplasty or operation.
