国产真丝涤纶血管移植物自然内皮化的研究

Experimental study of emdothelialization on domestic silk dacron graft

采用真丝涤纶人造血管行腹主动脉移植。结果显示:术后10天吻合口管壁有较完整的纤维组织性吻合,并有内皮细胞覆盖,血管内壁有血细胞形成的一薄层血栓覆盖,10天后开始机化变成纤维组织,逐渐被内皮细胞覆盖,术后1个月移植血管内形成较完整的内皮,但并不完善,3个月血管内皮才被一单层内皮细胞完整覆盖。

Domestic silk - dacton grafts were used to operate on dogs for abdominal aerfa replacement. 10 days after operation,incomplete fibrosis generated and was covered by endothelial cells at the anastomosis. A thin layer of thrombosis composed of blood cells covered the interal surface of the graft. 10 days later,thrombolic or ganization and endothelialization occured. One month after the operation,majority of the internal surface of the graft was covered by endothelium.and completed till the third month later.
