Three dimensional reconstruction and hemodynamic analysis of budd-chiari syndrome vascular / 实用放射学杂志

ABSTRACT

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.
