Algorithm for autologous breast reconstruction for partial mastectomy defects.
BACKGROUND
The use of lateral thoracic skin and fat for breast reconstruction is advantageous because it does not require the use of muscle transfer, and the donor-site incision is well hidden under the arm. In patients with redundant skin at the thoracic flank, use of this tissue has the added benefit of removal of an unsightly roll. The lateral thoracic skin and fat flap can be harvested using microsurgical technique based on three different pedicles: the thoracodorsal artery perforators; a direct cutaneous branch of the thoracodorsal, axillary, or lateral thoracic arteries; and the lateral thoracic intercostal perforating vessel.


METHODS
The authors describe the techniques for harvest of lateral thoracic tissue based on each of the pedicle options. A case is then presented to illustrate each option, and an algorithm is suggested for deciding which pedicle to use.


RESULTS
The authors have used lateral thoracic tissue for partial breast reconstruction for a variety of defects. In this report, the authors review the results of three illustrative cases.


CONCLUSIONS
Partial breast reconstruction may be required for patients after breast-conserving therapy or after breast reconstruction by other methods. Lateral thoracic tissue can be safely transferred to correct defects in treated or reconstructed breast, or to obtain symmetry. Knowledge of the vascular anatomy to this region is helpful in understanding the pedicle options when harvesting this tissue. The authors present an algorithm for determining which pedicle is most appropriate for the transfer of lateral thoracic tissue for partial breast reconstruction.
