Oliguria or anuria in the postoperative period of a post-transplant patient must alert the transplant team for a possibility of vascular problem and requires high clinical suspicion for early diagnosis and prompt decision making.

We report a case of sudden anuria in a renal transplant recipient during the immediate post-operative period, wherein prompt decision to re-operate and explore identified an external iliac artery dissection compromising the perfusion to the renal allograft. The dissected segment was irreparable, hence, was resected and reconstructed using a non-autogenous graft, restoring the perfusion to the allograft and lower limb. The renal graft was explanted, re-perfused and subsequent end to side anastomosis of the allograft arteries to the vascular graft was done. The patient had improved diuresis and decreasing creatinine trend as well as absence of lower extremity ischemic symptoms during the postoperative period.

Polytetrafluoroethylene (PTFE) interposition is an essential salvage technique for restoring blood flow in cases of external iliac artery dissection during renal transplantation.
