Background: We would like to present an unusual case of simultaneous stenosis of renal graft artery and vein diagnosed four months after transplantation. both treated by stent placement. Our aim is to point at the fact that renal graft venous stenosis is very rarely reported in the literature and – as it is not easy to diagnose by routine US - it could be overlooked. If early detected it can be treated by stent placement. Case presentation: We present a case of 36-old-male with renal failure who received a kidney graft from deceased donor. The patient experienced delayed graft function. No rejection was found in the biopsy. Four months after transplantation the kidney function deteriorated to sCr 280 µmol/l. Graft artery stenosis together with graft vein stenosis was revealed. Both lesions were dilated with stent placement, the graft function returned to 230 µmol/l and became stable for 10 years. Ten years after stent placement graft function deteriorated to 300 µmol/l. An in stent restenosis of arterial stent was detected. It was successfully dilated by the balloon, the graft function returned to 230 µmol/l and stays stable for another 5 years. Conclusions: An unusual simultaneous transplanted kidney artery and vein stenosis treated by stent placement is presented. The patient had stable graft function for 15 years after the procedure with one re-intervention on arterial stent. [ABSTRACT FROM AUTHOR]

Abstract Background We would like to present an unusual case of simultaneous stenosis of renal graft artery and vein diagnosed four months after transplantation. both treated by stent placement.

If early detected it can be treated by stent placement. Case presentation We present a case of 36-old-male with renal failure who received a kidney graft from deceased donor. The patient experienced delayed graft function. No rejection was found in the biopsy. Four months after transplantation the kidney function deteriorated to sCr 280 µmol/l. Graft artery stenosis together with graft vein stenosis was revealed. Both lesions were dilated with stent placement, the graft function returned to 230 µmol/l and became stable for 10 years. Ten years after stent placement graft function deteriorated to 300 µmol/l. An in stent restenosis of arterial stent was detected.

Conclusions An unusual simultaneous transplanted kidney artery and vein stenosis treated by stent placement is presented.
