We demon- strate a case of ipsilateral external IAS proximally to anastomosis in a kidney recipient, which manifested with renal failure and claudication, and was success- fully treated with endovascular stent placement. Keywords Iliac artery stenosis Á Renal transplant Á Renal failure Á Claudication Introduction Kidney transplantation is the preferred method for treatment of end-stage renal disease. Expanding the indications for kidney transplanta- tion with increased inclusion of older patients leads to a increased number of recipients with peripheral arterial disease [1]. Although iliac artery stenosis (IAS) is a rare complication after renal transplanta- tion, responsible for various disorders such as hypertension and renal dysfunction [2]. We demonstrate a case of ipsilateral external iliac artery (EIA) stenosis proximally to anastomosis in kidney recipient, which manifested with renal failure and claudication, and was successfully treated with endovascular stent placement. Case report A 60-year-old male patient was admitted to our hospital with complaints of right leg pain after walking a distance of 100–150 m. Two years earlier, kidney transplantation from a living donor had been performed due to renal failure due to bilateral kidney atrophy, requiring three sessions of hemodialysis per week for 8 months. His anamnesis was also remark- able for a history of heavy smoking well before and after kidney transplantation. There was no history of previous rejection. The patient also had a history of coronary artery disease and had undergone coronary artery bypass surgery 7 years ago. Auscultation of the patient’s cardiac and lung areas was normal. There was a bruit above the renal transplant in the right iliac fossa. Distal pulses from the lower extremities were diminished at the right side while left side pulses were normal. Patient’s systolic blood pressure was slightly increased (140/70 mmHg). The laboratory examination showed increased values of blood urea nitrogen (26 mg/dl), plasma creatinine (1.8 mg mg/ dl) with reduced clearance (51.85 ml/min), increased level of potassium (5.8 mmol/l) and calcium K.
