Abstract    The research of hemodynamic characteristics in abdominal aortic aneurysm focuses on blood pressure, blood flow, aortic wall stress, shear stress, as well as the physio-pathologic changes caused by the specific hemodynamic situations. The hemodynamic characteristics lead to aortic aneurysm progressing, asymmetry and mural thrombosis. Meanwhile, the spatial structure of abdominal aortic aneurysm results in the particular hemodynamic characteristics. Researching of the hemodynamic status is an important method of analyzing the development and rupture risk of abdominal aortic aneurysm, and make prevention and treatment strategies.
