摘要：

腹主动脉瘤内的血流动力学主要研究瘤体内的动脉压、血流的状况，以及血流作用于主动脉壁的张力和剪切力的分布情况，同时研究主动脉壁随血流动力学改变发生的相应的结构和功能改变。血流动力学因素导致腹主动脉瘤发生并逐渐增大，呈不规则形态生长，瘤体内形成附壁血栓；而瘤体的形态改变同时也改变其内血流动力学特点。明确腹主动脉瘤内的血流动力学特点，有助于分析疾病进程，评估腹主动脉瘤破裂的风险，指导临床治疗工作，同时为早期预防腹主动脉瘤的发生和发展提供理论依据。

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.
