采用经皮腔内血管成形术（PTA）治疗了 109 例 141 处肾动脉狭窄患者，其中 58 例药物治疗失败。最初的成功率为94%。 55 名患者患有严重弥漫性动脉粥样硬化，40 名患者患有肾功能不全。迄今为止，已有 36 名患者（50 处狭窄）接受了总共 52 次随访血管造影研究。所有病例均获得了临床数据，包括血压反应。 98 名高血压患者中只有 7 名对 PTA 没有反应。在 11 名主要因肾功能不全而接受治疗的患者中，5 名病情有所改善。在 29 名 BUN 和肌酐也升高的高血压患者中，13 名患者的肾功能得到改善。总共有 96 名患者 (88%) 从该手术中受益。长期结果分析表明，PTA 应成为纤维肌性发育不良和短节段动脉粥样硬化病变的首选治疗方法，并且还可能有助于改善肾功能不全。
Percutaneous transluminal angioplasty (PTA) was used to treat 109 patients with 141 renal artery stenoses, including 58 patients in whom medical management was unsuccessful. The initial success rate was 94%. Fifty-five patients had severe diffuse atherosclerosis and 40 had renal insufficiency. Thus far, 36 patients (50 stenoses) have undergone a total of 52 follow-up angiographic studies. Clinical data, including blood pressure response, were obtained in all cases. Only 7 of the 98 hypertensive patients failed to respond to PTA. Of the 11 patients treated primarily for renal insufficiency, 5 improved. Of the 29 hypertensive patients who also had elevated BUN and creatinine, renal function improved in 13. Altogether, 96 patients (88%) benefited from the procedure. Analysis of long-term results suggests that PTA should be the treatment of choice for fibromuscular dysplasia and short, segmental atherosclerotic lesions and could also prove helpful in improving renal insufficiency.
