title: Rethinking the superficial inferior epigastric artery flap in breast reconstruction: Video demonstration of a rapid, reliable harvest technique.
abstract: Abdominal-based autologous free tissue breast reconstruction has undergone significant changes over the past decade. The evolution has focused on limiting morbidity of the donor site. The transition from the transverse rectus abdominus muscle free flap to the muscle-sparing transverse rectus abdominus muscle free flap to the deep inferior epigastric artery perforator free flap has markedly improved abdominal-based autologous breast reconstruction. However, all of these flaps involve an incision through the anterior rectus fascia and potential damage of intercostal motor and sensory nerves. The superficial inferior epigastric artery flap (SIEA) reliably perfuses the ipsilateral hemiabdomen, yet does not violate the fascia or any motor nerves. As a result, the incidence of hernia, abdominal wall weakness and bulging is essentially eliminated. Nevertheless, use of the SIEA flap remains marginal. Vessel size, dissection difficulties and lack of understanding of the relevant anatomy have limited its acceptance. The present article describes a rapid, reliable and safe dissection technique with an algorithm for harvesting the SIEA flap in autologous breast reconstruction.
