Abstract:
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.
