[Experimental study on vascularized area of the prefabricated axial skin flap after implantation of vascular bundles].
Thirty-eight New Zealand white male rabbits were used to study vascularized area of the prefabricated axial skin flaps (PASFs) after implantation of vascular bundles (VBs) into subcutaneous tissues of the animal's abdomen. Influential factors were investigated including the interval after implantation, the size of VBs, the subcutaneous layer where VBs were implanted and simultaneous skin expansion. The results indicated that the suitable time for PASFs transferring was 3-4 weeks after implantation of VBs. The VBs of larger diameter prefabricated larger area of PASFs. Larger areas of PASFs were created by implanting VBs into the subcutaneous layers that possessed rich vascular plexuses. It was possible that the expanded PASFs could be transferred.
