Abstract

Since Willam Harvery had proposed the concepts of circulation in 1628. the anatomy and physiology of circulation has been intensively studied. Venous drainage of a musculocutaneous flap was shown to be of importance for the prevention of necrosis and successful flap taken.
We created an experimental model in rats in which the illiolumbar veins were used as the draining veins, and the following experiment was performed.
The experimental models were divided into 3 groups ;
Group I: bilateral illiolumbar neurovascular bundles of the grafts were not preserved as a control.
Group II: preserving the bilateral illiolumbar veins as the draining veins.
Group III: silastic sheet was placed between the musculocutaneous flap and the underlying bed. In this study, it was demonstrated that
1) Necrosis could be prevented by draining veins.
2) Group II with draining veins : it indicated that the number and size of the draining veins were critical for the survival of the flap.
3) Group III with silastic sheet protection of plasmatic circulation was showed that flap could not survived.
