CFD Analysis for Disruption of Hepatic Blood Flow Balance Caused by Hepatic Transplantation

控制术后病程是肝移植和经皮肝穿门静脉栓塞术(PTPE)中的一个严重问题。这两种手术都改变了手术后肝脏的血流平衡，随后导致肝脏局部和整体肿胀。在某些情况下，肝功能衰竭是由手术引起的。为了防止失败，在手术前需要有定量和数值的预测方法。本研究建立了肝静脉血流的数值模型；几何模型由患者的CT图像数据建立，并进行了计算流体动力学(CFD)分析。结果表明，本研究构建的外周血管模型能够较好地模拟门静脉的实际血流平衡。

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.
