摘要
真皮下血管网皮瓣近年来已广泛用于烧伤整形中皮肤缺损的修复，临床资料表明，此种“超薄皮瓣”长宽比例最大可达到7：1，皮瓣形状可根据受区创面需要设计成不规则形，断蒂时间由传统皮瓣的3周提前到术后1周左右，皮瓣愈后不臃肿，外形美观，对面颈部及四肢烧创伤引起的皮肤缺损修复具有很高的美学价值。通过10侧动脉灌注乳胶的成人新鲜尸体的显微解剖发现，颈肩肱部真皮下血管网皮瓣的血供可由蒂部通过稠密吻合的真皮下血管网层获得，又可通过暴露的真皮下血管网与受区早期建立血供而具有2套血供系统，皮瓣无缺血期，血流量大，成活率高。
Subdermal vascular network skin flap (SVN flap)has widely been applied to repair the skin defects onburns and plastics in recent years. Clinical resultsdemonstrated, the greatest length to breadth ratio of' supra - thin flap' can reach 7: 1. The flap can bedesigned as irregular shape according to therequirement of the recipient site. The time of pedicledivision can be advanced to one week from threeweeks in the traditional flap. After healing, the flap'scontour is beautiful without sulkiness. It is verysuitable for repariing the skin defects of face, neckand extremities on burns and wounds and gets a highaesthetic value. Having micro-dissected in 10 freshcadavers perfused Latex well in artery, We found theblood supply of cervico -shoulder -humeral SVN flapnot only came from the pedicle by means of subdermalvascular network layer anastomosed heavy, but alsofrom the early revascularization between thesubdermal vascular network plane and the recipientsite, so SVN flap owned two vascular systems withoutischemic time. Because of great blood flow, itsviability was high.
