Objectives To explore a novel hepatic duct cast with transparent liver parenchyma and internal ducts. Methods A fresh human liver was harvested and the hepatic and portal veins were perfused. And the sectional images were obtained by a 64-slice spiral CT. The three-dimensional (3D) models of the portal vein, hepatic vein and liver parenchyma were reconstructed using Mimics software. The shell molds of the liver parenchyma and its connection with ducts were designed in software Magic 4.0. The 3D models were then uploaded into a rapid prototype 3D printer to physically duplicate the models. After assembling the cast and the shell structures, the mold was manufactured. Melted transparent jelly wax was then poured into the mold. After wax solidification, the shell molds were removed. And the novel RP(rapid prototype) hepatic cast was produced. Result The novel RP cast of human liver with transparent parenchyma and internal ducts was successfully produced. It had a fine morphology and a good hand feeling with the transparent jelly wax. And the duct structures of the portal vein and hepatic vein were clearly displayed in different colors with their intimate relationship demonstrated. The smallest branch of the RP cast of hepatic ducts was about 1.2 mm in diameter. Conclusion The RP cast of human liver can demonstrate the details of the liver structure and is convenient at reservation It can expand the application of the duct cast in medical education, research and clinical trials.
