Successfully Rescued Renal Graft Artery Thrombosis by Ex Vivo Thrombectomy: A Case Report

Abstract A 40-year-old woman who had been suffering from type II diabetes mellitus and consequent end-stage renal disease underwent living related kidney transplantation. The graft renal artery was anastomosed to the right internal iliac artery (end-to-end). Postoperative renoscintigraphy demonstrated normal graft perfusion. The serum lactate dehydrogenase level increased abruptly at postoperative day 15 and digital subtraction angiography disclosed graft artery thrombosis. Despite an intervention using a metallic coil stent, the rapid formation of thrombus occluded the graft artery completely. In an emergent surgical operation, the graft was nephrectomized carefully and irrigated after extensive thrombectomy. The graft was reimplanted by using an internal iliac artery graft. After three consecutive hemodialysis treatments, the patient's kidney graft functioned well. She has been in good health with stable graft function for 3 years after the operation.
