Background: Although liver transplantation is widely accepted as the therapeutic strategy for end-stage liver failure, complication of hepatic venous outflow obstruction remains lethal. Currently, ensuring a single wide orifice in both the graft and recipient inferior vena cava has been proposed to avoid hepatic venous outflow obstruction with no theoretical concept. Methods: We herein report a standardization technique for the reconstruction of the hepatic vein based on the causal analysis. Results: During the put-in process, the graft must be positioned in contact with the recipient diaphragm and slightly pushed to the cranial direction to simulate the state after abdominal closure. Because there is no extra space between the graft and diaphragm, the graft could not rotate about the anastomotic site of the inferior vena cava toward the diaphragm after abdominal closure as the intestinal pressure increases, and accordingly hepatic venous outflow obstruction does not develop. Conclusions: With this concept, all transplant surgeons can successfully and easily perform hepatic vein reconstruction without total clamping of the inferior vena cava and without outflow block.
