Applied anatomy for living-related liver transplantation in pigs

Objective:To study the anatomic foundation for living related liver transplantation(LRLT) in pigs. Methods:Ten adult pig livers were used in this study.The topographic anatomy and vascular cast specimens of these pigs were studied from the following items:the segments and lobes,the distribution of arteries,portal veins,biliary tract and hepatic veins.Results: From outside,the pig liver consisted of three major lobes:the left lateral lobe,median and right anterior lobe,and the right posterior lobe.The caudal lobe cannot be distinguished from near lobe clearly.The dividing midline of the median lobe was the border of the left and right lobe.In this line/face,there was no important vessel and other structure. Conclusion: The pig living related liver is a good model for transplantation and the left half liver should be chosed as donor graft.
