A 79-year-old man developed bilateral intermittent claudication. Peritoneal dialysis had been initiated at 55 years of age to manage chronic renal failure. In addition, he underwent kidney transplantation at 61 years of age. His Ankle-Brachial Index (ABI) was 0.82 and 0.71 for the right leg and left leg, respectively. Furthermore, his serum creatinine level had increased from 0.98 mg/dL to 2.38 mg/dL over the past 2 years. CT angiography revealed focal calcified stenosis in the terminal abdominal aorta. However, ultrasound revealed no significant stenotic lesion in the supplied artery bound to the transplanted kidney from the right external iliac artery. We performed endovascular therapy for abdominal aortic stenosis using the pressure gradient. Following the procedure, the patient’s symptoms disappeared and the ABI increased to 1.25 and 1.14 in the right leg and left leg, respectively. Furthermore, the serum creatinine level improved to 0.96 mg/dL.
