title: [Experimental study of survival mechanism of skin flap with subdermal vascular rete].
abstract: OBJECTIVE
  To determine the blood supply style and survival mechanism of skin flap with subdermal vascular rete.
  
  
  METHODS
  The skin flap on trunk of piglets were taken as experimental pattern. The survival length of skin flap was examined and the nuclear element distribution in the skin flap was determined by ECT.
  
  
  CONCLUSIONS
  This study demonstrated that the distal portion of super-long flap with subdermal vascular rete fail to getting blood supply from its pedicle. This kind of flap is actually a combination of flap and free graft with subdermal vascular rete. This kind of super-long and super-wide flap is actually not a flap but a free skin graft. The survival of super-long and super-wide flaps with subdermal vascular rete rely on the blood supply from the wounds and their edges partially or completely. Their survival style is actually free grafting.
