Prefabrication of a flap may represent a new alternative, not limited by natural vascular territories, for creating donor sites. Experimental procedures in which an A-V shunt results in sufficient flap neovascularization have been reported. This study was undertaken to investigate how neovascularization from the recipient bed affects survival of this type of flap. An 8-cm x 10-cm prefabricated skin flap, nourished by the left epigastric vein, was constructed in a rabbit abdomen. In half the models, a silicone sheet was placed under the flap, to impede neovascularization from the bed. The flaps of both experimental groups showed excellent viability, and no statistically significant difference in survival rate was recognized. This flap was found to be independent of the vascularity of the underlying bed.
皮瓣预制可能是一种不受天然血管区域限制的创建供区的新方法。已有报道通过动静脉分流实现皮瓣充分新生血管化的实验方法。本研究旨在探讨受区床的新生血管化如何影响此类皮瓣的存活。在兔腹部构建一个由左腹壁静脉供血的8厘米×10厘米预制皮瓣。在一半的模型中，在皮瓣下方放置硅胶片，以阻止来自受区床的新生血管化。两个实验组的皮瓣均显示出良好的活力，且存活率无统计学显著差异。发现该皮瓣不依赖于其下方受区床的血管。
