Hepatic venous outflow obstruction (HVOO) is a critical complication after living-donor liver transplantation (LDLT) potentially associated with graft insufficiency; however, modalities to detect the impaired hepatic venous outflow have not been established.
This study investigated the usefulness of computational fluid dynamics (CFD) to analyze the hepatic venous outflow after LDLT.
The show that CFD unveiled early and otherwise undetectable abnormalities of the hepatic venous outflow, which impaired graft liver regeneration. CFD would be useful to optimize the management of the graft liver outflow after LDLT.
