The area of the buttocks provides another source of tissue for breast reconstruction. The SGAP can be taken from the upper area of the buttocks. SGAP stands for superior gluteal artery perforator. A distinction is made between an upper (superior: SGAP) and a lower (inferior: IGAP) flap. Like the DIEP flap, this is also a perforator flap that is freely transplanted, and is therefore a free flap. The removal of a GAP flap is technically more demanding than a DIEP flap, because the vessels are much smaller and more fragile. This procedure therefore places higher demands on the surgeon and his or her experience in microsurgery.
There are several reasons to choose an SGAP. Many patients already have large scars on the lower abdomen or too little abdominal fat, so the DIEP flap is either inappropriate or not possible. Many patients also do not want scars on their back, and therefore decide against a breast reconstruction using back muscle. Others are very definite that they do not want artificial breast implants. In all these cases, breast reconstruction with autologous tissue from the buttocks is a very good alternative.
