| 摘 要： | 为了改善冠状动脉搭桥术后的血流动力学，提出了对称双路搭桥的改进措施。利用有限元分析方法，对冠状动脉搭桥术中单路移植管和对称双路移植管内的生理流动进行了数值模拟，并对两种情况下的血流动力学计算结果进行了比较。计算结果分析了缝合区附近的流场、壁面剪应力等血流动力学因素在心动周期内的时空分布情况。研究结果表明，对称双路搭桥比单路搭桥具有更合理的血流动力学，可以避免动脉粥样硬化的危险性血流动力学因素，从而减少手术再狭窄的发生。

| Abstract: | For the purpose of improving the hemodynamics of CABG, the authors presented a new amelioration measurement of symmetric 2-way bypass graft. The physiological blood flow in 1-way and 2-way bypass graft of coronary is simulated with finite element method, and the data on computational hemodynamies of these two eases were compared. The temporal-spatial distributions of hemodynamies during the cardiac cycle such as flow patterns and wall shear stress in the vicinity of anastomosis were analyzed. The study results showed that 2-way bypass graft was of more rational hemodynamies when compared with 1-way bypass graft, and it could improve the flow conditions and decrease the probability of restenosis, |
