Anatomic and clinical study of rectus abdominis musculocutaneous flaps based on the superior epigastric system: ipsilateral pedicled TRAM flap as a safe alternative.
This anatomic and clinical study supports the use of the ipsilateral transverse rectus abdominis musculocutaneous (TRAM) flap over the contralateral TRAM flap for breast reconstruction. The costomarginal artery was constant in these dissections and supplied a vascular pedicle to the rectus abdominis muscle. Radiologic studies confirmed the communications between the costomarginal artery and the deep epigastric system, the same as between the costomarginal artery and the musculophrenic and intercostal arteries. The results of the clinical series confirmed the costomarginal artery as an alternative or adjuvant vascular pedicle of the deep superior epigastric artery in cases of potential lesion of the latter. The lack of pedicle tension because of the shorter distance to be transposed allowed a greater versatility in flap shaping and positively affected its aesthetic result. This fact made the authors change from the contralateral to the ipsilateral pedicled TRAM flap as the first option for autologous breast reconstruction because of vascular security.
