摘　　要：以猪作为动物模型，对带真皮下血管网超薄皮瓣的血运重建规律进行了探讨。以超薄皮瓣为实验组，保留真皮下血管网皮片为对照组，按自身配对原则随机分为６个组。通过荧光素显色，透明标本，组织学，明胶墨汁灌注过程中超薄皮瓣的染色情况等观察，发现超薄皮瓣的再血管化发生在术后第５天，至第７天新生血管通过塑形趋于成熟。它既发生在皮瓣与受床之间，又发生在皮瓣与创缘之间，而且由皮瓣成活部分远端渐至近端。o study the blood supply and revascularization of super thin skin flaps with a presserved subcutaneous vascular retwork , we carried out a randomized self-matched experimental study in 10pigs. The free skin grafts with a preserved subcutaneous vascular network served as control. All skingrafts and flaps were divided into 6 groupe, besed on the potoperative days (1st , 3rd, 5th , 7th , 10thand 14th day). The revascularization of flape were assessed by means of intravenous fluorescein test ,tissue transparent method, and histology (light microscope, electron microscope), especially, thestained color change of the flaps from ink instillation.The experimental results indicated that: revascularzation were found on 5 days after operationand vessel remodelling was on 7th day , Neovascularization for flap survival was demonstrated as smollblood vessels arising from both the wound edges and bed. Revascularization of flap proceededgradually from the distal to the proximal and the timing of revascularization was quicker than that oftraditional flaps.
