ABSTRACT
Breast reconstruction with autogenous tissue has become increasingly popular during
the past several decades. Reconstruction has been successful using many donor sites,
but the abdomen remains the overwhelming choice. However, it is estimated that, in
15 to 20% of patients who undergo mastectomy, the abdomen is not suitable as a donor
site. The back, buttocks, and thighs can serve as alternative donor sites in those
cases. Our group previously described the superior gluteal artery perforator (S-GAP)
flap for breast reconstruction.[1] Since 1993, this flap has been used at our institution as a first-line alternative
in patients where the abdomen is judged to be inadequate as a donor site. Based on
our success with the deep inferior epigastric perforator artery[2] flap, harvesting only fat and skin from the abdomen, we became interested in applying
perforator techniques to the gluteal region. Dissection of the vascular structures
out of the muscle proved to be advantageous by providing a much longer pedicle and
a much easier dissection of the parent vessels when compared with the gluteal myocutaneous
flap.[3] In this article we present our 8-year experience with 127 S-GAP flaps. Flap survival
was 98%, with an overall complication rate of 17%. Patient satisfaction of the reconstructed
breast and donor site has been excellent. Although the technique is not an easy one
to learn, it does provide a reliable flap and an excellent esthetic reconstruction.
When the abdomen is not available, the authors feel strongly that the S-GAP flap should
be used as an alternative site before considering other options for breast reconstruction.
