| 摘 要： | 血栓性疾病大多发生在弯曲和血管分叉的位置附近,其形成机制和原因比较复杂,目前的研究主要集中在临床病例的治疗护理方面.临床观测表明,动脉疾病的发病机制和病变发展与血流动力学特征(如流场分布、壁面剪应力等)密切相关.采用计算流体力学方法,从血流动力学角度研究了弯曲血管中血液流动的改变对血管栓塞形成的影响.主要从血流入口初始速度、弯曲曲率半径、血管管径及血液黏度方面研究血液流动对血栓形成的影响.同时结合相关医学病例.从多学科角度分析并验证医学研究中有关血管弯曲对血栓形成机理的猜测.

| Abstract: | Thrombus mostly occurs at the position near vessel bifurcation and sinuousness,whose formation mechanisms are relatively complicated and not clearly understood.Most investigations are now focused on the treatment and nursing of clinical cases and vitro experiments of medical thrombolysis.Clinical observations indicate that the formation mechanisms and pathological development of artery diseases have a close relationship with blood kinetics characteristics (such as distribution of flow field,wall shear stres... |
