Keywords: Vessels, Velocity & Flow, iliac venous compression
Motivation: Hemodynamic changes are important for evaluating Iliac venous compression syndrome. CFD simulation can obtain individualized and quantitative hemodynamic information that traditional imaging methods cannot obtain.
Goal(s): Qbtain hemodynamic parameters through the establishment of patient individualized vascular model and CFD simulation. By observing hemodynamic parameters, the changes in blood flow caused by iliac venous compression can be more accurately evaluated.
Approach: The 3D model is constructed based on the MRA images. After CFD simulation, changes of flow dynamics parameters observed due to the influence of iliac venous compression.
Results: The CFD simulation shows that iliac venous compression can cause significant changes in hemodynamics
Impact: Hemodynamic changes are the pathological basis of iliac venous compression. Accurate diagnosis of blood flow changes is helpful to guide the surgical treatment of iliac venous compression and provide powerful help for clinical decision-making.
