左冠状动脉前降支的血流动力学分析
An Analysis of Hemodynamics of the Anterior Descending Branch of the Arteria Coronaria Sinistra

摘要: 本文对左冠状动脉前降支的血流动力学特性进行了分析.结果表明,开口处的90°分叉和壁冠状动脉的形成乃是前降支的血流动力学特征.由这些特征所产生的冲击压力、湍流剪切应力、附加压力和旋涡形成是导致该动脉易发粥样硬化的重要因素.Abstract: This paper analyses the anterior descending branch of the arteria coronaria sinistra from the view of hemodynamics.The results show that the branching of the anterior descending branch with an angle of 90° at the opening and the formation of the mural arteria coronaria are the hemodynamic characteristics.The shearing stress of the turbulent flow, the additional pressure, the formation of the blood vertex, and the impulsive pressure, caused by these characteristics, are hemodynamic reasons that leads to the occurence of atherosclerosis in anterior descending branch.
