Cavoportal transposition for portal vein thrombosis in a pediatric living‐related liver transplantation
2003
We report a case of a living-related liver transplantation in a child in whom diffuse thrombosis of the portal venous system required the use of recipient vena cava to perfuse the donor portal vein (cavoportal transposition). An 8 ½-month-old infant with biliary atresia received the left lateral segment of his father's liver. The child's portal vein was irretrievably thrombosed, as were the splenic and superior mesenteric veins. A cavoportal anastomosis provided excellent flow to the liver, and there was no engorgement of the graft, which had good immediate function. The main postoperative problem was loss of 3 to 3.5 liters of ascitic fluid through the drain for 2 weeks. The ascites eventually resolved over a period of 4 weeks. Twenty-four months after transplantation, the child is thriving on a normal diet and has no ascites. A Doppler examination showed good flow in the cavoportal anastomosis.
