The SGAP, or Superior Gluteal Artery Perforator Flap,
was developed by Dr. Robert Allen
in 1993. We were also the first to perform the bilateral
simultaneous SGAP in 1994, and our experience has subsequently
This is an excellent option for women who do not have ample abdominal
tissue to donate for breast reconstruction or for those who would
prefer to use the upper buttock as a donor site.
Almost all patients are candidates for use of the upper buttock
(the SGAP) for breast reconstruction. This donor site can be used
for unilateral or bilateral simultaneous reconstructions.
This donor site differs from the IGAP in its position
on the buttock, the resulting scar placement and the blood
vessel used to supply the tissue. For the SGAP it is the superior
(upper) gluteal artery, and for the IGAP it is the inferior (lower)
gluteal artery. The SGAP scar lies in the upper buttock and is easily
hidden in a French cut bikini or in underwear. The IGAP scar lies
within the lower buttock crease. Otherwise these donor sites are
comparable in terms of the reconstruction they provide.
Which buttock donor site to chose is a matter of preference
and anatomy. Both the IGAP and the SGAP can be used for
unilateral or bilateral simultaneous reconstruction.
