Abstract

Occlusive disease of the iliac segment, proximal to the transplant artery (prox-TRAS), in kidney transplant recipients is a rare complication. Prox-TRAS, located in the common iliac artery, is extremely rare in these patients. Herein, we present an interesting case of a common iliac artery stenosis that manifested as decreased allograft function and uncontrolled blood pressure without other typical clinical symptoms. The patient was successfully treated with percutaneous luminal angioplasty and stent insertion.
