A Rare Cause of Hypertension and Acute Renal Failure in Kidney Transplant Recipients

One of the postoperative vascular complications in renal transplantation is stenosis of the transplant renal artery. Stenosis of the iliac segment proximal to the transplant renal artery (Prox-TRAS) is an uncommon cause of graft dysfunction and hypertension. Impaired arterial perfusion of the transplant may be the leading cause of graft dysfunction or refractory hypertension. Selective treatment with percutaneous transluminal angioplasty (PTA) improves kidney function and hypertension. We report two cases with prox-TRAS and renovascular hypertension after renal transplantation. The stenosis was in the iliac segment of anastamosis in these two cases.
