Résumé
It is possible to obtain two good-quality hepatic transplants from a single cadaveric liver by separation of the right and left lobes of the liver. We attempted to define a relationship based only on donor body weight for predicting donor total liver weight as well as donor right (segments V-VIII) and left (segments II-IV) hepatic lobe weight. Segment I (caudate lobe) is resected and thus lost in this procedure. The study was performed on 60 human cadaveric livers. We correlated cadaveric body weight (mean + or - SD), 72.43 + or - 9.54 kg, with total liver weigh, 1.54 + or - 0.36 kg, and right and left lobe weight, 0.88 + or - 0.23 kg and 0.65 + or - 0.17 kg, respectively, with total liver weight. A formula was obtained by linear regression which provided the following relationships: total liver weight (g) = [245.57 + 17.92 x (body weight, kg)]; right lobe weight (g) = [67.58 + 0.52 x(total liver weight, g)]. The selection of the recipient on the liver transplant waiting list can be made on the basis of these relationships
