Superficial Inferior Epigastric Artery (SIEA) Flap Reconstruction

Similar to a DIEP flap procedure, in a Superficial Inferior Epigastric Artery (SIEA) flap procedure, we utilize fat and skin from the lower abdomen – preserving the abdominal muscles - to reconstruct a natural breast after mastectomy.


In this procedure, the fat and skin from the abdomen are used to create a breast. The tissue and accompanying blood vessels are attached using microsurgery at the new breast site. The end result is a breast incision that is circular or oval; the skin within the scar was once from your abdomen.


The abdominal scar will run from hip bone to hip bone, and this may be concealed by undergarments. Similar to a DIEP flap, patients experience the added benefit of a “tummy tuck” at the time of reconstruction.


Not all patients are surgical candidates for a SIEA flap reconstruction. The SIEA flap differs from the DIEP flap in that it utilizes different arteries to supply blood flow to the new breast. The arteries associated with a SIEA flap are small and might not be adequate for all patients.
