Abstract
Subsegmental patterns in 85 human livers were studied after preparing corrosion casts of the hepatic duct, hepatic artery and portal vein by injecting colored butyl butyrate solution. A subsegment was identified by the independence of its vessels and ducts from those of its neighbors. Nine hepatic subsegments were observed: posterior superior, posterior inferior, anterior superior, anterior inferior, medial superior, medial inferior, lateral superior, lateral inferior and caudate. Sizes of the subsegments were very similar in 41 cases (48.23%). In the others, some increase or decrease in size of 1 or more subsegments at the expense of neighboring subsegments was observed. These variations were illustrated.
