Pages 60 - 64
Abstract
Objective: Thoracic and abdominal aortic aneurysm is a very difficult problem in the field of vascular surgery. According to discoveries of basic medical in recent years, hemodynamic changes are very important factors affecting the development of aneurysms. Methods: Three-dimensional of patients' CT images with thoracic and abdominal aortic aneurysms is reconstructed by medical imaging modeling software MIMICS, using ANSYS ICEM CFD 14.5 to divide the model into unstructed grids, finally using ANSYS 14.5 analysis hydrodynamics of thoracic and abdominal aortic aneurysms. The fluid pathline of blood flow distribution in the model, distribution of dynamic pressure and shear stress on the wall of blood vessels are obtained in this article. Results: when the blood flow inlet velocity is different, the blood flow distribution of the human thoracic and abdominal aorta is significantly different. Conclusions: According to the pressure and shear stress in individuals with thoracoabdominal aortic aneurysms, the formation of aortic aneurysm is closely related to hemodynamics, provide effective help for clinical diagnosis and treatment.
