Breast reconstruction by the free lower transverse rectus abdominis musculocutaneous flap.

Free TRAM flap transfer for breast reconstruction following mastectomy overcomes the shortcomings of the pedicled TRAM flap. It ensures the perfusion of the entire flap via its dominant vascular pedicle and allows for flexibility in the design of the ensuing breast mound. The authors' experience with ten free lower TRAM flap transfers is reviewed. The present surgical technique is described and three cases are presented to illustrate its application. The advantages and limitations of the method are compared particularly with its pedicled version.
