摘要
为研究动脉吻合术后弹性纤维的修复过程 ,在手术显微镜下将 90只大鼠股动脉横行切断后行端端吻合术 ,术后 3、7、14、2 1、30、90天取材 ,采用Weigert弹性纤维染色及甲酸消化法扫描电镜观察弹性纤维在动脉吻合术后的重构。结果发现 ,动脉吻合术后弹性纤维的修复分为静止期、增生期、重建期 ;动脉壁的弹性纤维在动脉吻合术后经历了重建过程 ,吻合后弹性纤维的修复为新生内膜的模式 ;动脉吻合术后 30天弹性纤维的含量明显增高且形态结构趋于正常。
To study the repairing process of elastic fiber after anastosis of artery, 90 femoral arteries of rats were divided and end-to-end anastomosis was performed. 3,7,14,21,30, and 90 days after anastomosis, the arteries were harvested and the restructuring of the elastic fiber of ananstomosed arteries was studied with formic acid digestion method and observed under scanning electronic microscope. Three main stages could be identified in the course of elastic fiber restructaring: stage 1, quiescent stage; stage 2, proliferation stage; and stage 3, reconstruction stage. After anastomosis of an artery, there was a remodeling process involving elastic fibers, and the repair of elastic fiber takes a neointimal model. The amount of elastic fiber increases markedly 30 days after the anastomosis, and its morphological structure becomes stable.
