The surgical anatomy of the liver has been investigated in 80 cadaveric specimens, the subject being studied with the use of corrosion casts of the liver, by careful anatomical dissection of the porta hepatis and hepatic veins and by dye injection of blood vessels and bile ducts supplying the liver. The results of these findings are now described, with particular attention to the lobar and segmental structure of the liver, and to the distribution of the hepatic artery, bile ducts, portal vein, collapsed umbilical vein and hepatic veins within and outside the liver. The clinical application of these findings in massive liver resection and infusion chemotherapy, in the diagnostic and therapeutic value of the collapsed umbilical vein, the interpretation of cholangiograms, the significance of aberrant bile ducts, and liver transplantation is outlined.
