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 +/- SD), 72.43 +/- 9.54 kg, with total liver weight, 1.54 +/- 0.36 kg, and right and left lobe weight, 0.88 +/- 0.23 kg and 0.65 +/- 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)]; left lobe weight (g) = [-63.38 + 0.47 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.
通过分离肝脏的左右叶，从单个尸体肝脏中获取两个高质量的肝移植供体是可行的。我们试图仅基于供体体重来定义一种关系，以预测供体全肝重量以及供体右肝叶（第V - VIII段）和左肝叶（第II - IV段）的重量。在这个过程中，第I段（尾状叶）被切除并因此丢失。该研究对60个人类尸体肝脏进行。我们将尸体体重（均值±标准差），即72.43±9.54千克，与全肝重量1.54±0.36千克以及右叶和左叶重量（分别为0.88±0.23千克和0.65±0.17千克）与全肝重量进行关联。通过线性回归得到一个公式，该公式给出了以下关系：全肝重量（克）= [245.57 + 17.92×（体重，千克）]；右叶重量（克）= [67.58 + 0.52×（全肝重量，克）]；左叶重量（克）= [-63.38 + 0.47×（全肝重量，克）]。肝移植等待名单上受体的选择可以基于这些关系来进行。
