Division of Donor Liver for Successful Split-Liver Transplantation in Pigs

抄録

Split Liver Transplantation (SLT) is an attractive method to solve the problem of a shortage of liver grafts. A through knowledge of the anatomy of the porcine liver vessels and bile duct is essential in performing the experimental SLT. This study was undertaken to decide the split line for successful SLT in pigs by examining the main branching patterns both vessels and bile duct in 30 porcine livers macroscopically and angiographically. The hepatic arterial branching patterns were divided into three types and bile duct patterns into two types. There was no exception in branching patterns of the portal vein and the hepatic vein. We conclude it is desirable that the donor liver should be divided into two grafts between the left medial lobe and quadrate lobe.
