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.

D000005 Abdomen That portion of the body that lies between the THORAX and the PELVIS. Abdomens
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.

D012867 Skin The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D013524 Surgical Flaps Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
