Abstract:
Objective The hemodynamic mechanism of Budd-Chiari syndrome ( BCS ) has become the research hotspot in recent years.The aim of this study was to discuss the hemodynamic characteristics of BCS through 3D numerical simulation for inferior vena cava stenosis based on the fluid dynamics ( CFD) method. Methods 3D model was established from a patient with Budd-Chiari syndrome based on MR image with Ansys software .The numerical simulation of this model was performed by the CFD . Results The 3D model of inferior vena cava functionally demonstrated the change procedure of hemodynamic characteristics of BCS .Vortex was found above the narrow area , and blood flow velocity achieved maximum in the center of the stenosis throughout the coronal section graph.The static pressure value gradually declined at the narrow area entrance to the narrowest place , and achieved minimum value at the exit.The maximum wall shear stress existed in the stenosis . Conclusion Specific 3D computational hemodynamic model can show the hemodynamic characteristics of BCS , and its hemodynamic parameters could be used for clinical practice .It will facilitate the study on correlation of complex hemodynamic parameters and morphology changes of inferior vena cava vascular .
