摘要
肺高压(pulmonary hypertension,PH)是由不同病因引起、以肺血管阻力和压力进行性升高为特点的一种致死性疾病,异常血流动力学在其发生发展中具有重要作用。计算流体动力学(computational fluid dynamics,CFD)作为一种新方法应用于临床研究中,可无创获取患者个体化病灶部位三维空间任一点的血流动力学指标,并可通过可视化技术将其呈现,逐渐成为一种可深入了解血流相关疾病进展的有力工具。对近年来CFD应用于肺高压相关肺循环血流动力学研究中涉及的数值模拟方法、边界条件、血液特性以及主要的血流动力学参数进行综合阐述。
Pulmonary hypertension( PH) is a devastating disease caused by different etiology and characterized by the progressive elevation of pulmonary vascular resistance and pulmonary artery pressure.As a new method that applied to clinical studies,computational fluid dynamics( CFD) gradually becomes a powerful tool for in-depth understanding of the disease progression.It can noninvasively obtain the patient-specific hemodynamic parameters at any point of the vessel and present them through the visualization technology.In this paper,an overall review of CFD with the focus on PH,including the numerical simulation method,boundary conditions,blood characteristics and relevant hemodynamic parameters was presented.
