A 57-year-old Japanese female was considered for living donor liver transplantation (LDLT) due to end-stage liver cirrhosis caused by primary biliary cholangitis with portal vein thrombosis (PVT) formation. A 26-year-old daughter of the patient was selected as a living donor; however, a computed tomography examination revealed trifurcated-type portal vein anomaly (PVA). Preoperative liver volumetry showed that the right lobe graft was necessary for the recipient; therefore, reconstruction of the portal vein bifurcation during LDLT was necessary. We planned to extract the recipient's own hepatic vein grafts after total hepatectomy, and these would be attached with anterior and posterior portal branches as jump grafts. We performed laparoscopic donor hepatectomy as usual, and the recipient's hepatic vein grafts were anastomosed on the bench. Then, the liver graft was inserted, and the hepatic vein reconstruction was routinely performed. We confirmed the alignment between the recipient's portal vein and the bridged hepatic vein graft of the liver graft's posterior branch, and anastomosed these two vessels. Moreover, we confirmed the front flow and expansion of the reconstructed posterior branch by declamping only the suprapancreatic side of the portal vein. The decision regarding the punch-out location was crucial. We confirmed the alignment between the reconstructed posterior branch and the bridged hepatic vein graft of the anterior branch, and anastomosed these two vessels employing the punched-out technique. In LDLT, liver transplant surgeons occasionally encounter living donors with PVA or recipients with PVT. Our contrivance may be useful when the liver graft needs reconstruction of portal vein bifurcation.
