真皮下血管网皮片基底血运建立的研究

Study of central bed blood supply to skin graft with subdermal vascular network

为探讨真皮下血管网皮片基底血运对皮片成活的作用，采用５４只豚鼠，观察了真皮下血管网皮片边缘血运阻断时基底血运建立的情况，以及厚薄不一的皮片移植后成活情况。结果：真皮下血管网皮片边缘血运阻断时，皮片仍可成活。结论：真皮下血管网皮片基底部血运对皮片成活起重要要作用，临床上可以修剪成厚薄不一的真皮下血管网皮片进行移植。

Central bed blood circulation of skin graft with subdermal vascular network was studied byblocking peripheral blood supply with silicone sheet on animal model.Skin grafts with differentthickness(i.e. subdermal vascular network was preserved in sonle area of a full thickness skin graft)wereused to transfer in guinea pigs.Over 92% of skin grafts were suvived.The study has shown that central bedblood supply is also important for the skin graft with subdermal vascular network circulation makeing theskin graft survival.
