摘要
我们通过１０条犬的涤纶血管移植实验研究，连续观察分析了中口径国产涤纶人造血管移植于犬腹主动脉，术后１２周以内不同时期移植血管的组织形态学改变。结果表明２ｃｍ长国产中口径涤纶人造血管移植于腹主动脉后其新生内膜覆盖管腔内壁大约需要４周。新生内膜主要来自邻接动脉内膜的平滑肌增生爬行；内皮细胞覆盖人造血管内膜的时间较自体静脉晚得多，术后７周涤纶血管内膜尚无完整稳定的内皮细胞层；经高压蒸汽灭菌法消毒过的中口径国产涤纶人造血管不宜再次使用。
Abstract After dacron vessel transplantation in 10 dogs,weanalysed the middle-bore Chinese dacron grafts trans-planted to the abdominal aorta of dogs and observedhistomorphologically changes of the grafts in differentstages within 12 weeks, 2cm-long dacron artificial ves-sel transplantation to the abdominal aorta took 4week9 for the new endothelial membrane,which main-ly comes from the proliferation of the contiguous arte-rial endothelial smooth muscle fibers,to cover the in-ner wall of the grafts。 More time was needed for en-dothelial cells than the self vessels to cover the dacrongrafts the dacron grafts endothelial membrane was notintact and stable in 7 weeks after operation. The auto-claving dacron grafts should not be used repeatedly.
