چکیده

Perforator flaps represent the latest in the evolution of soft tissue flaps. They allow the transfer of the patient’s own skin and fat in a reliable manner with minimal donor-site morbidity. The powerful perforator flap concept allows transfer of tissue from numerous, well-described donor sites to almost any distant site with suitable recipient vessels. The inferior gluteal artery perforator (I-GAP) flap is one option that allows a large volume of tissue to be used for breast reconstruction with minimal donor site morbidity. The ideal tissue for breast reconstruction is fat with or without skin, not implants or muscle. Absolute contraindications specific to perforator flaps in our practice include history of previous liposuction of the donor site, some previous donor site surgery, or active smoking (within 1 month prior to surgery). Perforator flaps are supplied by blood vessels that arise from named, axial vessels and perforate through or around overlying muscles and septa to vascularize the overlying skin and fat. The I-GAP flap is based on one or more perforators from the inferior gluteal artery. During flap harvest, these perforators are meticulously dissected free from the surrounding muscle, which is spread in the direction of the muscle fibers and preserved intact. The vascular pedicle is anastomosed to recipient vessels in the chest and the donor site is closed directly. The I-GAP flap provides an excellent option for the safe, reliable tissue transfer from the buttock for breast reconstruction with minimal donor site morbidity.
