Controlling postoperative course is a serious problem in liver transplant and percutaneous trans-hepatic portal embolization (PTPE). The both surgeries change blood flow balance in the operated liver, subsequently brings on local and overall swellings of the liver. In some cases the liver failure is occurred by the operations. In order to prevent the failure prediction method is required before the surgeries quantitatively and numerically. This study developed numerical model for blood flow in hepatic vein; geometric model was made from patient’s CT image data and performed Computational Fluid Dynamics (CFD) analysis. As a result, this study made clear the peripheral blood vessel model constructed in this study was able to simulate actual blood flow balance in portal vein.
