| Popis: | Summary:. Anterolateral thigh (ALT) free flaps have become reliable options for head-to-toe reconstruction. Although perforator anatomy is fairly predictable, in cases of eccentric perforator location, we proposed shifting the entire flap laterally and preserving a medial bipedicled flap between the original incision and the new medial flap margin. This facilitates primary donor site closure instead of harvesting a flap larger than anticipated. We conducted a retrospective chart review of ALT flaps performed between 2007 and 2019 and identified patients who underwent bipedicled closure of the donor site. Demographics, flap characteristics, and surgical technique were evaluated. Six patients had bipedicled donor site closure related to primary perforators located lateral to the original flap design. The mean defect size was 91 cm2, and bipedicled flap width ranged from 4 to 6 cm. All donor sites were closed primarily. Five of the donor thigh sites healed without complications, and 1 patient had superficial delayed healing of the medial bipedicled incision, which healed with local wound care. The ALT has become an invaluable flap in microsurgical reconstruction, yet it is not without limitations. Primary donor site closure is generally not feasible for larger flaps, thus necessitating skin grafting of the donor site and/or prolonged wound care. Our technique facilitates primary closure of the donor site in patients who otherwise would have required harvest of a larger than necessary flap based on eccentric perforator anatomy. The medial bipedicled flap is straightforward, reproducible, and allows for modifications of the original flap design to better fit the defect. |
