The lateral transverse thigh free flap: an alternative for autogenous-tissue breast reconstruction.
|
| Abstract |
The lateral transverse thigh free flap is a horizontal variant of the more commonly known vertical tensor fasciae latae myocutaneous free flap. Fresh cadaver injections of the lateral circumflex femoral artery indicated simultaneous perfusion of the upper lateral thigh tissues and the standard tensor fasciae latae territory extending down the lateral thigh. These experimental data strongly indicated that the clinical application would be successful. The flap is composed mostly of fat from the prominence of the upper lateral thigh ("saddlebags") based on a small plug of underlying tensor fasciae latae muscle. The amount of skin that can be included with this flap is limited in a vertical dimension to about 6 to 8 cm but is determined by the ability to close the defect. We have performed 17 flaps in 11 patients with up to 18 months of follow-up. Ten were delayed and 7 were immediate reconstructions. The chest and hip dissections are performed simultaneously by two microsurgeons. There has been one flap loss due to arterial disruption on day 3. An early problem was seroma formation in the donor site, which has been improved in the later patients by closing the dead space with sutures. The lateral transverse thigh free flap has the following advantages over other methods of autogenous-tissue breast reconstruction: (1) longer, more peripherally placed vessels, (2) easier flap dissection and no need to turn the patient during the procedure, (3) decreased postoperative morbidity and more rapid recovery, (4) reduction of an area of excess fat in those patients in whom the hips are more prominent than the abdomen, (5) greater intrinsic internal projection of the flap, and (6) excellent vascularity. The disadvantages of the flap are (1) microsurgery is required, (2) the amount of skin available is not as great as that with the gluteal or transverse rectus abdominis musculocutaneous (TRAM) flap, (3) the scar on the upper lateral thigh is probably more visible than on the buttock or the abdomen, and (4) a balancing procedure on the opposite hip is usually necessary in unilateral cases. Our current indications for the lateral transverse thigh free flap are (1) the transverse rectus abdominis musculocutaneous flap is unavailable, (2) for a particular breast size, the thigh fat proportions are greater than the abdominal proportions, or (3) the patient prefers this option to the transverse rectus abdominis musculocutaneous or gluteus flap. Results and complications with the lateral transverse thigh free flap will be presented along with pertinent comparisons with the other choices for autogenous-tissue breast reconstruction.
