| Living-related partial liver transplantation is an effective therapy for the shortage of donor liver in the end-stage disease of children. Because of the complex of the construction within the liver, it was limited in some district in the world to perform living-related liver transplantation. The cutting of the living donor liver consists of computation of the liver volume, the dissection, acquirement and reconstruction of donor partial liver arteries, bile duct and portal veins with these of the recipient, and the restore of the hepatic veins of the donor liver. Among these processes, any one may have affection on the living-related liver transplantation. And donor undergoes an operative stroke during the operation. The present study, including six parts, through the study the rule of the liver inner construction and combined with some specific living-related transplantation methods, is aimed to provide the applied anatomy for surgical treatment of living-related liver transplantation. Materials and Methods: 1. 30 formalin-fixed adult cadaver livers were dissected and studied the gross anatomy, construction of the arteries, bile duct, portal veins and hepatic veins according to left and right half liver respectively. And the long and diameter of the vessels and ducts were measured. 2. 30 adult fresh livers were casted with filling material through the liver arteries, bile duct, portal veins and hepatic veins respectively. 10 livers were casted through one of the vessels or ducts. After the casting forms toke shape and were trimmed, they were studied the gross anatomy, construction of the arteries, bile duct, portal veins and hepatic veins within these livers. 3. The middle hepatic fissure, the left fissure between the left lateral lobe and left medial lobe and the left lateral lobe segmental fissure 憊ere measured the location in the start point, the end point and the middle parts. 4. Imitating the cutting of the living-related partial liver. 5. 10 formalin-fixed children cadavers were studied and measured the liver and the circumstance structures, consisted of the portal veins, arteries, bile duct, hepatic veins and their branches. Results 1. The left half liver The anatomic structures of portal vein consisted of 4 types. The left portal vein can be divided the transverse part, angle part, sagittal part and cystic part. Abnormal of the left portal veins involved an atypical structure of the trunk and an variation branch to right lobe come from left portal vein. The arteries came from proper hepatic artery, left hepatic artery and right hepatic artery. The aberrant arteries were left inferior phrenic artery, left gastric artery and right gastric artery. The artery structures were divided Stypes. The bile ducts had 6 types. The branches of left were the bile duct of left medial lobe, the upper segment of the left lateral and the inferior segment of the left lateral lobe. 2. The right half liver: The anatomic structures of portal vein consisted of 4 types. Type A, the right portal vein was typical; Type B ,no truck of the right portal vein; Type C, the right portal vein divided into 3 branches; Type D, abberant branch came from left portal vein. The artery came chiefly from the right hepatic artery. The bile duct had 4 types. The right hepatic vein were one trunk in 39 livers, had 2-5 branches in 21 livers which diameter was 0.3-0.85cm, each liver had 5-18 branches veins with diameter 0.10-0.30cm. The long of the right...
