摘　　要：目的：探讨动脉分支处是否存在湍流区。方法：用荧光剂标记大鼠肠系膜微血管和血小板，在活体微循环显微镜下，观察和记录血小板在不同角度，微动脉分支部位的流变行为。结果：血小板以层流方式流经微动脉分支部位，在分支区域不发生碰撞、聚集和滞留。说明动脉血流方向的改变不足以在分支区域形成湍流和使血小板激活。结论：从流变学角度来看，小动脉端侧吻合不增加血栓形成的机会。The rheological behaviors of platelets at the arteriolar bifurcation region in rat mesenteric microvasculature was observed to investigate the influence of arterial flow direction alteration on platelets flow pattern. the platelet flow at the arteriolar bifurcation region was still laminar and platelet aggregation was not observed. This experiment indicated that the alteration in arterial flow direction did not cause turbulence and platelet activation at the bifurcatioin site, which did not reduce flow volume or increase thrombosis at the end-to-side anastomotic site in small arteries.
