Successful third renal transplantation in a child with an occluded inferior vena cava: A novel technique to use the venous interposition between the transplant renal vein and the infrahepatic inferior vena cava

A girl aged 11 years and 3 months with occlusion of the inferior vena cava had experienced two renal transplant graft failures since birth. The third renal transplant from a live donor was carried out. Preoperative evaluation showed that the arteries from the right common to the right external iliac artery were absent, and the ilio‐caval vein was occluded below the level of the renal vein. The donor's renal artery was anastomosed to the aorta. The donor's ovarian and large saphenous veins were used to extend the transplant renal vein to the recipient's patent inferior vena cava. The present report concludes that the extension of a short donor renal vein using other donor veins is a viable therapeutic option for pediatric patients with vascular occlusions.
