The superior gluteal artery perforator flap: an additional tool in the treatment of sacral pressure sores.

We describe the use of a large skin-subcutaneous tissue flap based on one perforator of the superior gluteal artery (SGA) to reconstruct large midline posterior defects in one stage. The integrity of the gluteus muscles is preserved and we feel this is particularly important in non-paralysed patients. Donor sites were always closed primarily. Use of the superior gluteal artery perforator (SGAP) flap preserves the entire contralateral side as a future donor site. On the ipsilateral side, the gluteal muscle itself is preserved and all flaps based on the inferior gluteal artery are still possible. We recommend this flap in an area where reconstructive possibilities are limited, as it preserves other reconstructive flap options, both on the ipsilateral and contralateral sides.
