含高密度真皮下血管网皮片移植术的研究

Study of the Skin Grafting with Intact Subdermal Vascular Network of High Density

目的对比研究不同供皮区的真皮下血管网密度及其对保存真皮下血管网皮片移植质量的影响。方法选择由锁骨区和侧胸区两个不同部位供皮的保存真皮下血管网皮片,分别对其真皮下血管网密度进行对比分析。同时对38例锁骨区供皮及158例侧胸区供皮的保存真皮下血管网皮片移植病例进行疗效对比观察。结果①锁骨区皮片的真皮下血管网密度比侧胸区皮片的密度高。②在受区血运条件相同的情况下,含有高密度真皮下血管网的锁骨区保存真皮下血管网皮片移植,其成活质量优于密度较低的侧胸区皮片。结论含高密度真皮下血管网皮片的移植,更易成活,质量更高。用于面部皮肤缺损的修复,具有皮瓣移植之功效,而无臃肿之弊。

Objective To compare ane study the density of the subdermal vascular network of different donor site and its relationship with the survival quality of the intact subdermal vascular network skin grafting(ISVNSG). Methods The density of subdermal vascular network of both clavicular site and subaxilla lateral thoracic site were compared anatomically while both 38 cases of ISVNSG with clavicular donor site and 158 cases of ISVNSG with subaxilla lateral thoracic donor site were compared clinically.Results ①The density of subdermal vascular network of clavicular site was higher than that of subaxilla lateral thoracic site;②Clinical observation revealed that the survival quality of the skin graft containing subdermal vascular network of high density was better than that of low density,in the same condition of recipient sites.Conclusion The skin graft with intact subdermal vascular network of high density survives more easily, and shows better survival quality.It can be well used to repair the defect on facial site as a skin flap without excessive thickness.
