摘　　要：自体静脉移植术是目前医学界普遍采用的治疗血管狭窄、改善组织缺血的重要手段和基本方法，是血管外科最常见的术式之一。然而，由于移植损伤、静脉与动脉的组织结构、血流动力学差异，自体静脉移植术后的通畅率仍不容乐观。本文将从血液流变学的角度对自体静脉移植术后再狭窄的形成过程进行研究。Autogenous vein graft is one of the frequent methods to treat ischemia in Vascular Surgery. However, the patency rate of vein grafts is unhappy because of the injury, the difference structure between arteries and veins, and the change of hemodynamics after grafted. The restenosis of vein graft contains three syntrophic component elements-thrombosis, intima hyperplasia, and scleratheroma. In this article, we will discuss the relationship between the changed hemodynamics and the restenosis of the vein grafts.
