Abstract:
A superior advantage of the superficial circumflex iliac artery perforator flap is that any donor site residue can easily be hidden by clothing. Usually designed as narrow or moderate-sized flaps based on medial perforators of the superficial branch, this readily allows primary donor site closure. However, for larger flaps, tension-free closure requires that the thigh remain flexed or even a skin graft used. Another alternative would be to use an adequate lateral perforator of the deep branch, if available, as the vascular hub of a propeller flap that extended into the adjacent flank, that could then be rotated into the medial groin to facilitate simultaneous direct closure of both flap donor sites.
