Abstract reoogni tion of skin areas wi th an axial patterned vascular supply has paved the way for the free-one- stage transfer of flap and composite flap tissue by microvasou¬lar anastomosis to a recipient site. The obvious advantages of free flap tissue transfer are a one-stage operation, decreased hospitalization and economio loss, reduced discomfort and greater seleotivity of donor si tea for speoific p urp o ses , Open joints and fraoture site can be primarily resurfaced with flap tissue, thereby salvaging the~underlying structures. There are several conditions whdch must be satisfied at both donor and recipient sites if a free flap is to be transferred with satisfactory results. At the donor site, the flap must contain a main pair of vessels which consistl of, at least, one artery and one vein, with diameters su¬fficient for microvascular anastomosis. Also the main pe.d icle vessels must form a closed arteriovenous system in , which the blood supply emerges through the pedicle artery and drains back into the pedicle vein. The vasoular net¬work should be wide enough to nourish the entire flapo Lastly, no seoondary functional disturbances and obvious |
