Transplant renal artery stenosis: hypertension and graft function before and after angioplasty

We present a case, who after 15 years of renal transplantation developed se vere deterioration of her hypertension without alteration in renal function . Colour Doppler sonography revealed a 90% stenosis near the anastomosis of the graft artery to iliac artery, which was successfully and uneventfully corrected by percutaneous balloon angioplasty. Following the procedure the blood pressure control dramatically improved and her antihypertensive regim en returned and remained at baseline for the subsequent year of observation . Renal function remained normal and stable before and after angioplasty.
