近年来,计算流体力学(computational fluid dynamics,CFD)被广泛应用于脑动脉瘤的基础和临床研究中,其研究方向涉及:1动脉瘤的形成、生长机制和动脉瘤破裂的血流动力学危险因素,2通过建立患者个性化模型,评估弹簧圈和支架置入后动脉瘤内流场的变化,评价血管内治疗的效果。从计算流体力学模型的建立、评估动脉瘤破裂风险的形态和血流动力学参数以及血流动力学参数评估动脉瘤治疗的手术效果3个方面详细阐述近年来在脑动脉瘤的诊治中血流动力学研究的进展。 In recent years, computational fluid dynamics (CFD) is widely used in basic and clinical studies of cerebral aneurysms. Its research interests include: 1 the formation of aneurysms, the growth mechanism and the hemodynamic risk of aneurysm rupture Factors, 2 Evaluate the effect of endovascular treatment by establishing a personalized patient model to assess changes in the flow field within the aneurysm after coil and stent placement. From the establishment of computational fluid dynamics model, the assessment of aneurysm rupture risk morphology and hemodynamic parameters and hemodynamic parameters to evaluate the surgical treatment of aneurysms in three aspects elaborated in recent years in the diagnosis and treatment of cerebral aneurysm in the blood flow Progress in Kinetic Studies.
