SGAP flap
Pronunciation: S-gap
Also written as: SGAP — Superior Gluteal Artery Perforator
Superior gluteal artery perforator flap used primarily in breast reconstruction procedures.
Full Definition
The SGAP (superior gluteal artery perforator) flap is a type of autologous tissue reconstruction that uses skin and fat from the upper buttock area, supplied by perforating vessels from the superior gluteal artery. This flap is often chosen when DIEP or TRAM flaps are not viable options due to previous abdominal surgery or insufficient abdominal tissue. The procedure preserves the gluteal muscle while harvesting tissue for reconstruction, typically resulting in a well-concealed donor site scar along the upper buttock crease.
Usage
Usage note: Acronym should be in all capitals; distinguish from IGAP (inferior) variant.
