摘要
为了研究不同因素对血管束移植预构轴型皮瓣范围的影响,将血管束移植入38只雄性兔的腹部皮下,对术后不同时间、植入不同管径血管束、植入皮下不同层次以及同时埋入皮肤扩张器的预构轴型皮瓣,进行了皮瓣活体血管染色和移植存活范围的比较研究。结果提示:行预构轴型皮瓣移转的合适时机在术后的3～4周;大管径较小管径血管束及血管束植入受区较丰富的血管网层次其预构皮瓣的面积大;所预构的皮瓣范围,包括以血管束为轴的受区邻近区域和发自该区域走向皮瓣中远部的小动脉所支配的区域,呈不规整形态;植入血管束同时皮下埋入扩张器,于术后2周开始扩张,术后4周移转是可行的。
Thirty-eight New Zealand white male rabbits were used to study vascularized area of the prefabricated axial skin flaps(PASFs)after implantation of vascuar bundles(VBs)into subcutaneous tissues of the animal's abdomen.Influential factors were investigated including the interval after implan- tation,the size of VBs,the subcutaneous layer where VBs were implanted and simultaneous skin expan- sion.The results indicated that the suitable time for PASFs transferring was 3～4 weeks after implanta- tion of VBs.The VBs of larger diameter prefabricated larger area of PASFs.Larger areas of PASFs were created by implanting VBs into the subcutaneous layers that possessed rich vascular plexuses.It was possible that the expanded PASFs could be transferred.
