Renal artery stenosis of the transplant kidney occurs in approximately 6% of renal allograft recipients. Severe bilateral renal artery stenosis and unilateral renal artery stenosis to a single functioning kidney have been described as causes of recurrent pulmonary edema in nontransplant patients with normal cardiac function. We report 2 patients with severe transplant renal artery stenosis who presented with recurrent episodes of acute pulmonary edema. Successful revascularization in 1 patient prevented the recurrence of pulmonary edema. In renal allograft recipients who present with unexplained recurrent episodes of acute pulmonary edema, who do not have an obvious cardiac cause, transplant renal artery stenosis should be considered as a possible etiology.
移植肾肾动脉狭窄发生于约6%的肾移植受者中。严重双侧肾动脉狭窄以及单侧肾动脉狭窄累及单个功能肾，已被描述为心功能正常的非移植患者反复发生肺水肿的原因。我们报告2例严重移植肾动脉狭窄患者，他们表现为急性肺水肿反复发作。1例患者成功进行血管重建后预防了肺水肿复发。在出现不明原因急性肺水肿反复发作且无明显心脏病因的肾移植受者中，应考虑移植肾动脉狭窄为可能的病因。
