Correlation between drainage area volume of middle hepatic vein and liver function.
OBJECTIVE
Complete outflow is impossible to maintain on both sides in donors undergoing hemi-liver graft harvesting, because the middle hepatic vein (MHV) can be preserved on only one side. The area in which outflow veins are disrupted becomes congested, and does not sufficiently regenerate.


METHODS
The subjects of the study were 55 living donors who provided the left liver with caudate lobe, including the MHV. The midpoint between the tributaries of the MHV and the right hepatic vein was determined preoperatively with computed tomography. The midpoint between the tributaries of the MHV and right hepatic vein and the borderline between the right and left liver were used to predict the MHV drainage area volume. Total bilirubin levels, the prothrombin time international normalization ratio, and alanine aminotransferase were measured in donors on postoperative days 1, 3, 5 and 7.


RESULTS
The parameters that correlated with the MHV drainage area volume included total bilirubin on days 5 and 7, prothrombin time international normalization ratio on day 3, and alanine aminotransferase on day 7.


CONCLUSIONS
Middle hepatic vein drainage area volume, calculated using the present method, correlated with early liver function after left liver harvesting with the MHV.
