The Versatile Superficial Inferior Epigastric Flap for Breast Reconstruction

Abstract

The superficial inferior epigastric flap is a versatile free flap that has added to the techniques available for autogenous breast reconstruction. It is especially advantageous when previous thoracic radiation and/or abdominal surgery preclude the use of conventional transverse rectus abdominis musculocutaneous flaps. Eight superficial inferior epigastric flaps were used to reconstruct 7 breasts in 6 patients. In 4 patients the superficial inferior epigastric flap was used as part of a composite free flap. In 1 patient, a lower abdominal wall flap was transferred on bilateral pedicles. In another, bilateral flaps were raised to reconstruct both breasts. The superficial inferior epigastric flap offers several advantages. It uses relatively abundant lower abdominal wall skin and subcutaneous tissue while preserving the underlying fascia and rectus muscles. A cadaver study illustrates the clinical territory of this flap. The superficial inferior epigastric flap provides an excellent option for autogenous free flap reconstruction of the breast, alone or in combination with other flaps.
