Abstract

Estimation of graft volume (GV) is critical in living donor liver transplantation. This study examines the accuracy of formula-derived GV estimates and compares them to both radiogically-derived estimates and actual measurements. We first compared formula-derived estimates of GV and compared them to actual volumes to provide estimates for both right lobe (RL) and left lateral segment (LLS) GV. We then applied these formulae to a validation cohort. Finally, we evaluated both formula-derived and radiologically-derived estimates by comparing them to actual GV measurements. There is a marginal concordance between formula-derived calculation and GV for RL donors, but the error ratio was lower than for radiologic estimates. In contrast, MRI measurements for LLS grafts demonstrated a lower error ratio than formula-derived estimation. Formula-derived estimates of GV should be routinely used in the initial screening of potential living donors as long as their limitations are appreciated.
