Iliac atherosclerosis is common in renal transplant recipients. In severe cases, it affects intraoperative renal arterial anastomosis and increases the risk of postanastomosis complications. At present, safe and efficient vascular replacement methods are relatively limited. In the 2 renal transplant cases at our center, described here, the donors' iliac arteries were unavailable. We therefore attempted to replace the recipients' diseased external iliac artery with the donors' inferior vena cava and then performed an end-to-side grafting with the attachment in arterial reconstruction. One patient received a single kidney transplantation, while the other received a dual kidney transplantation. Antiplatelet/anticoagulation drug application was avoided, and both patients were observed for more than 6 months. Stable renal graft function was achieved without any vascular complications. During this study, all procedures were in compliance with the Helsinki Congress and the Declaration of Istanbul. For end-stage renal disease patients with severe iliac atherosclerosis who are waiting for kidney transplantation, a donor's vena cava graft could potentially be a promising replacement option to restore external iliac artery patency and reconstruct renal blood flow, without the necessity of harvesting a recipient's autologous vessels or looking for costly artificial ones.
