Iliac artery stenosis as a cause of posttransplant renovascular hypertension: report of two cases.

Stenosis of renal artery (TRAS) or iliac artery proximal to the anastomosis (pTRAS) results in an impairment of kidney graft perfusion, arterial hypertension and in consequence decrease of glomerular filtration. In this report we present two patients with pTRAS and renovascular hypertension after kidney transplantation (KTx), treated successfully with percutaneous transluminal angioplasty (PTA) with stenting. Resistant hypertension, decrease of diuresis and increase of serum creatinine concentration were observed in both presented patients. Also in both cases pTRAS was diagnosed by Doppler ultrasonography and confirmed by angiography. Iliac artery angioplasty with stenting was successfully applied in these patients, resulting in a decrease of blood pressure, restoration of diuresis and a decrease of serum creatinine concentration. These observations confirm that PTA of iliac arteries with stenting is an effective method of treatment in patients with pTRAS.
