Controlling postoperative course is serious problem in liver transplantation. The transplantation changes blood flow balance in the liver consequently causes on local and overall swellings (deformation) of the transplanted liver. In order to prevent such the diseases prediction method is required before the transplantation surgery. This study build analytical method for blood flow in portal vein; geometric model was made from patient's CT image data and performed Computational Fluid Dynamics (CFD) analysis of blood flow in the portal vein. As a result of analysis, it was confirmed that this method was able to predict actual blood flow balance in the portal vein because the tendencies of calculation and measurement results conformed each other. In addition, blood flow in the left lobe of the portal vein showed different flow characteristics compared with right lobe; eddies were proceeded in the left lobe. These results mentioned here lead us detail blood flow characteristics in the portal vein and contribute to elucidation of the vascular disease.
