SGAP stands for Superior Gluteal Artery Perforator. As with the DIEP, the gluteal artery perforator arises from a branch of the gluteal artery, courses thru the muscle, to deliver blood to the overlying buttock fat. This procedure allows for use of buttock fat to reconstruct the breast when abdominal fat is inadequate. Similar to the DIEP it is also a “muscle preserving” procedure and doesn’t sacrifice the buttock muscles to collect the tissue (unlike the gluteal flap).
