Augmented SIEA flap for microvascular breast reconstruction after prior ligation of bilateral deep inferior epigastric arteries

Summary The superficial inferior epigastric artery (SIEA) flap is an excellent option for free tissue transfer breast reconstruction. Similar to the free transverse rectus myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flaps, the SIEA pedicle supplies the fasciocutaneous tissues of the lower abdomen. The SIEA flap does not involve removal of or potential damage to the rectus muscles. Nonetheless, the vascular pedicle may be a challenge to dissect and variable in its presence and caliber. This article presents a case report and an extended delay technique to augment the SIEA system in a patient with prior bilateral deep inferior epigastric artery ligation.
