A detailed knowledge of intrahepatic cholangiographic anatomy is essential for the recognition and management of pathology within the proximal biliary tree. The following postmortem study was designed to focus on the details of human intrahepatic anatomy. An associated clinical study was directed toward assessing the value of our present cholangiographic methods in demonstrating the proximal biliary tree.
Norman6 was one of the first to stress the importance of good proximal cholangiography in the management of stones within the substance of the liver. Fainsinger1 demonstrated the value of the correlative study of postmortem casts and cholangiograms of the human liver. We have combined a clinical and postmortem approach in order to assess ways in which we might improve the quality of our visualization of the proximal biliary tree and our ability to interpret variations and pathology within it.
Injection-corrosion preparations of 20 fresh human cadaver livers were
