DIEP Flap Breast ReconstructionIf you have a mastectomy to treat or prevent cancer, breast reconstruction can surgically recreate a natural-looking breast. One option for breast reconstruction is a deep inferior epigastric perforator (DIEP) flap procedure.

In a DIEP flap, the surgeon first excises skin and fat from the lower abdomen. This process does not require removing any of the rectus abdominus muscle, which houses the artery and vein that serve as the primary blood supply to skin and fat of the lower abdomen.

The excised abdominal tissue, or "flap," is then transferred to the mastectomy area. There, blood flow is restored by reconnecting the artery and vein to a set of vessels in the chest wall. The surgeon then shapes the flap to form a new breast.

Unlike the TRAM flap, the DIEP flap avoids using abdominal muscle. DIEP flaps thus take longer to complete. However, they may involve less postoperative pain and may reduce the risk of hernia formation.

Please note: A DIEP flap leaves a scar that extends along the lower abdomen, from one hip to the other. As a result, the recovery period may be longer than with breast construction with implants or tissue expanders.
