摘　　要：目的：应用计算机仿真的方法研究布-加综合征血管的血流动力学变化。方法基于 MRA 图像建立布-加综合征血管模型，利用 Ansys Fluent 软件进行血流参数仿真。结果成功建立布-加综合征血管模型，肝静脉3支主干与下腔静脉汇合处及其上方，血管压力变大、速度变缓、切应力变小。结论下腔静脉血流动力学变化区域与下腔静脉隔膜好发部位基本一致，与下腔静脉隔膜的发生存在一定的相关性，为研究布-加综合征的发病机制奠定基础。Objective In order to study the hemodynamics changes of the Budd Chiari syndrome vascular based on Computer Sim-ulation.Methods Three dimensional reconstruction model is established based on MRA medical images.Then take use of Ansys Fluent software to simulate hemodynamic parameters.Results Budd Chiari syndrome vascular model is established successfully. The hemodynamics changes on/above the vascular confluence of inferior vena cava with three main hepatic veins.Contract to the flow inlet of inferior vena cava,blood pressure becomes larger,the speed becomes slower and shear stress becomes smaller.Conclu-sion The inferior vena venous hemodynamics changes region is almost consistent with inferior vena venous predilection location. The study lays the groundwork for future study of Budd Chiari syndrome negotiations.
