大多数减少肾血流量的病变起源于肾动脉；大的、主动脉、动脉粥样硬化的斑块可以伸出肾口，导致功能性肾动脉狭窄。对45例连续的经皮腔内血管成形术进行了回顾性研究，并根据阻塞病变的位置和临床结果进行了分类。肾动脉狭窄对血管成形术的反应非常好，83%的患者表现出优秀或良好的结果。相反，当主动脉斑块导致血流阻塞时，76%的患者对球囊扩张的反应很差或根本没有反应。这种不同的反应可能反映了肾动脉和主动脉的肌层和前降层的弹性纤维和胶原纤维方向的解剖差异。
Most lesions that decrease renal blood flow originate within the renal artery; large, aortic, atherosclerotic plaques can overhang the renal ostium producing a functional renal artery stenosis. Forty-five consecutive percutaneous transluminal angioplasties were examined retrospectively and classified as to site of the obstructing lesion and clinical outcome. Stenoses within the renal artery responded very well to angioplasty, with 83% of patients showing either an excellent or good result. Conversely, when aortic plaques were responsible for inflow obstruction, 76% of patients responded poorly or not at all to balloon dilatation. This disparity of response may reflect the anatomic differences in the orientation of elastic and collagen fibers of the muscularis and advential layers of the renal artery and the aorta.
