[Experimental study of increasing effect of the fat flap tissue after delay operation on its free graft survival volume and duration].

Objective: To observe the effects of the fat flap tissues after delay operation on free fat-graft survival rate and duration.

Methods: The delay operation of fat flaps was performed in the inguinal region of a rabbit. Expression of VEGF was assayed using Elisa method after 12 hours of flap delay.
