[Application of computational fluid dynamics based on fluid-structure interaction in aortic dissection].

Aortic dissection is a life-threatening disease with acute onset,rapid progression and high mortality.Hemodynamic factors have important reference value in the development and treatment of aortic dissection.Computational fluid dynamics can intuitively and visually simulate the hemodynamic state of human blood vessels and quantify it numerically.However,computational fluid dynamics without fluid-structure interaction analysis cannot reflect the real situation of the human body.Therefore,the fluid-structure interaction numerical simulation of aortic dissection is worthy of further study to achieve more accurate evaluation of hemodynamic state,postoperative effect and risk prediction.In this paper,the application and research progress of computational fluid dynamics based on fluid-structure interaction technology in aortic dissection are briefly reviewed.主动脉夹层是一种起病急、进展快、病死率高的疾病。在主动脉夹层的发展和治疗过程中，血流动力学因素有着重要的参考价值。计算流体力学可直观、可视化地模拟人体血管内的血流动力学状态并进行数值量化，但未进行流固耦合分析的计算流体力学并不能反映人体真实情况，因此主动脉夹层的流固耦合数值模拟值得进一步研究，以达到对血流动力学状态、术后效果及风险预测等更准确的评估。本文就基于流固耦合技术的计算流体力学在主动脉夹层中应用及研究进展作一简要综述。.
