The Superficial Circumflex Iliac Artery Perforator Flap in Lower Extremity Reconstruction

The superficial circumflex iliac artery perforator flap is evolved from the groin flap, which was one of the early free flaps with a good concealed donor site. By further understanding the anatomy of perforators and elevating the flap based on it, this will provide added advantage of being a thin flap, harvesting as a composite flap, and help estimate the limit of skin paddle dimension. Despite these advantages, the relatively short pedicle still remains a challenge where long pedicle flaps are needed. One should select the flaps based on the recipient defect condition along with surgeons' experience, knowledge, and preference.
