Pectoralis major myocutaneous flaps in rats

A new neurovascular, island, myocutaneous flap, including the pectoralis major, was created in a rat model. This model is useful for the observation of muscle degeneration and skin changes due to ischemia or denervation. Although this model requires a delay procedure, it allows the flap, that can be used as a free myocutaneous flap, to be raised reliably.
