The Preferential Use of Subcutaneous Arteries (SCIA-SB and SIEA) in Abdominal-based Autologous Breast Reconstruction with a Modified Flap Design.

Background: Despite its many advantages, the deep inferior epigastric artery perforator flap requires fascial incision and intramuscular dissection, which can lead to pain and weakening of the abdominal wall. The superficial inferior epigastric artery (SIEA) flap offers an alternative to avoid this damage but is often considered unreliable due to its variable anatomy. In this study, we report our experience in autologous breast reconstruction using either the superficial branch of the superficial circumflex iliac artery (SCIA-SB) or the SIEA as the sole flap pedicle.
