An intraluminal stent fashioned from medical grade Silastic was used for technical assistance in performing 23 microvascular anastomoses. Twenty control and 20 stent arterial anastomoses were completed. Patency rates of 100 per cent in both the stent and control anastomoses were found by radical pressure testing immediately postoperatively and after an interval of two weeks. Electron microscopic and light microscopic studies showed no increase in damage to the vessel wall or increase in connective tissue reaction. Under the conditions of this experiment the Silastic stent can be used safely for assistance in performing microarterial anastomoses. Preliminary studies in six microvenous anastomoses have also shown no significant difference postoperatively between the stent and control anastomoses, both having a 100 per cent patency rate.
一种由医用级硅橡胶制成的腔内支架被用于辅助进行23例微血管吻合术。完成了20例对照动脉吻合术和20例支架动脉吻合术。术后立即及间隔两周后通过彻底的压力测试发现，支架吻合术和对照吻合术的通畅率均为100%。电子显微镜和光学显微镜研究显示，血管壁损伤未增加，结缔组织反应也未增强。在本实验条件下，硅橡胶支架可安全用于辅助进行微动脉吻合术。对6例微静脉吻合术的初步研究也显示，术后支架吻合术和对照吻合术之间无显著差异，二者通畅率均为100%。
