    Abstract:
    In pediatric renal transplantation in the setting of IVC thrombosis, the retrohepatic IVC or gonadal veins are often used for outflow. However, if use of systemic venous outflow is unsuccessful, options become limited. We report the use of the portal vein for venous outflow in kidney retransplantation in the setting of IVC thrombosis. The patient is a 19-month-old male who developed end-stage renal failure at seven months of age secondary to hypotension after spontaneous rupture of an accessory renal vein. The IVC was occluded during emergent laparotomy, and the patient developed extensive IVC thrombosis. The first two transplant attempts used the retrohepatic IVC for venous outflow. Despite good initial flow, in both instances the renal vein thrombosed on post-operative day 1. In an unsuccessful salvage attempt of the second transplant, a reno-portal anastomosis was performed. With few options for vascular access, a third transplant was attempted. The reno-portal stump from the second transplant was used for outflow. The patient recovered well from his third transplant (creatinine 0.6 mg/dL 35 months post-surgery), demonstrating that the portal vein can be used for outflow in cases of extensive IVC thrombosis.
