Obliterative hepatocavopathy (OHC) is a subtype of Budd-Chiari syndrome in which stenosis or obstruction of the retrohepatic inferior vena cava (IVC) is observed. Although IVC replacement is necessary in OHC patients, there are hardly any graft vessels available for IVC reconstruction during living-donor liver transplantation (LDLT). Here, we describe a novel technique of IVC reconstruction using only the autologous blood vessels in an OHC patient during LDLT. In this case, sufficient drainage of the hepatic outflow and reconstruction of the venous return from the lower half of the body were simultaneously required. Therefore, we substituted the retrohepatic IVC with the suprarenal IVC of the recipient, and we reconstructed the IVC continuity by using the autologous internal jugular vein and external iliac vein. The operation was safe, and the postoperative venous drainage from the hepatic tributaries was in good condition. This procedure might be an option for IVC replacement during LDLT.
