Abstract：
In order to provide a theoretical basis for the clinical treatment of thoracic aortic aneurysm, a 3D finite element model of thoracic aortic aneurysm was constructed and numerical simulation of hemodynamics was performed. Based on clinical patient-specific CT data, an optimized surface model of thoracic aortic aneurysm was constructed using digital image processing software Mimics 11. Then the surface model was exported into ANSYS ICEM CFD11.0 to generate volume mesh. At last CFD analysis was performed using ANSYS CFX11.0. Finite element model of patient-specific thoracic aortic aneurysm suitable for hemodynamics simulation was established. Distribution and changes of streamline, velocity vector, pressure and wall shear stress were obtained. Rupture mechanism of thoracic aortic aneurysms can be analyzed based on patient-specific model. Model with digital and patient-specific feature can be applied to hemodynamic analysis of thoracic aortic aneurysm.
