In a 58-year-old woman, the external iliac artery was accidentally dissected during the arterial anastomosis of a kidney transplant. An immediate CT angiogram showed an almost total occlusion of the common iliac artery. After the transplantation, radionuclide renography with Tc-99m MAG3 showed no flow across the right common iliac artery and no graft vascularization. Sequential images showed a photopenic area corresponding to the renal graft. These findings were interpreted as common iliac artery thrombosis and renal artery thrombosis associated with renal graft infarct. Excision of the transplant and iliofemoral bypass were performed. Pathologic examination of the graft showed massive acute renal infarct and renal artery thrombosis.
