The pedicled transverse partial latissimus dorsi myocutaneous flap for reconstruction of the radiated partial mastectomy defect

The pedicled partial latissimus dorsi myocutaneous flap based on the transverse branch of the thoracodorsal artery is described as it offers several advantages for reconstruction of radiated partial mastectomy defects. It maintains bulk and vascularity while having a favorable morbidity profile compared to the total flap. Specifically, seroma rates and length of drain use should be reduced. The anatomical location of the transverse branch allows creation of the flap outside the radiated field. Further, the flap preserves the lateral and inferior portions of the latissimus dorsi and the muscle is not detached from its insertion allowing preservation of the posterior axillary fold. Finally, the transversely oriented skin paddle offers favorable scar healing.
