The anatomical possibility of resecting the left lobe of the liver (segments II and III) in living subjects and using it for transplantation was evaluated. A group of 60 cadaveric livers were dissected at autopsy. The vascular and biliary elements of the left lobe were isolated and the lobe was resected and evaluated for possible grafting. The left lobe was 12–28% (mean 19.4%) of the liver mass. An extrahepatic segment of the left hepatic vein was isolated in 95% of specimens. Arterial blood supply to the left lobe consisted of a single artery (92%) or two arteries (8%). A single portal vein segment to the left lobe (type I) was found in 35% livers. Portal vein branches originated from a common orifice (type II, 35%) or separately (type III, 30%) from the left portal vein, and in these instances, preparation of a portal segment necessitated partial section of the left portal vein wall. Biliary drainage was extrahepatic in 56 livers and consisted of a single duct (type 1, 78%), or two ducts (type II, 15%). The resected left lobe was evaluated as satisfactory (single hepatic vein and artery, types I or II portal vein, type I bile duct) in 48% of cases, while a less-satisfactory lobe (type III portal vein or type II bile duct) was obtained in 33%. It was found anatomically difficult or impossible to resect the left lobe for possible transplantation in 11 (19%) liver specimens.
