What is the difference between a pedicled TRAM flap and a free TRAM flap?
In a pedicled TRAM flap, the tissue is passed inside the body behind the upper abdominal skin to the chest where the breast is then reconstructed. In a free TRAM flap procedure, the tissue is completely detached from the abdominal wall. Subsequently, the detached tissue is reconnected to an artery in the chest to re-establish blood supply, and is then shaped into a new breast.
