摘　　要：目的　探讨动脉吻合后顺应性及结构成份含量改变之间的关系。方法　在体测定狗股动脉端端吻合前及吻合后不同时相点的压力与直径 ,推导出动脉吻合前后的顺应性 ;术后取材 ,切片分别用 HE、Weigert、Aniline blue、Neubert染色 ,光镜观察 ,图像分析系统测量各结构成份相对含量。结果　动脉吻合后吻合口段的顺应性较吻合前逐日下降 ,吻合后第 14天下降最明显。各时相点弹性纤维变化无显著性差异 ,胶原纤维呈增加趋势 ;胶原纤维与弹性纤维含量之比值术后逐日增高 ,第 14天最高。结论　吻合后动脉的顺应性与血管结构成份改变有关。Objective\ To explore the relationship between the properties of compliance and the change of structure of components in anastomosed arteries.Methods\ The arterial pressure and diameter of femoral arteries of dogs were measured in vivo before and after arterial anastomosis in different time intervals to deduce the arterial compliance. The anastomosed arteries were removed and evaluated through light microscopic examination and various staining methods, the relative contents of elastin, collagen and smooth muscles were measured through image analysis system. Results\ The compliance of arteries was gradually decreased after anastomosis with peak time on the 14th day. The content of elastin at different time had no significant difference, while the content of collagen increased gradually, the ratio of them was increased.Conclusion\ The property of compliance of anastomosed arteries is closely related to the contents of the structural components.
