Customized reconstruction with the free anterolateral thigh perforator flap

From April of 2003 through September of 2006, 70 free anterolateral thigh (ALT) flaps were transferred for reconstructing soft-tissue defects. The overall success rate was 96%. Among 70 free ALT flaps, 11 were elevated as cutaneous ALT septocutaneous vessel flaps. Fifty-seven were harvested as cutaneous ALT myocutaneous "true" perforator flaps. Two flaps were used as fasciocutaneous perforator flaps based on independent skin vessels. Fifty-four ALT flaps were used for lower extremity reconstruction, 11 flaps were used for upper extremity reconstruction, 3 flaps were used for trunk reconstruction, and 1 flap was used for head and neck reconstruction. Total flap failure occurred in 3 patients (4.28% of the flaps), and partial failure occurred in 5 patients (7.14% of the flaps). The three flaps that failed completely were reconstructed with a free radial forearm flap, a latissimus dorsi flap and skin grafting, respectively. Among the five flaps that failed partially, three were reconstructed with skin grafting, one with a sural flap, and one with primary closure. The free ALT flap has become the workhorse for covering defects in most clinical situations in our center. It is a reliable flap with consistent anatomy and a long, constant pedicle diameter. Its versatility, in which thickness and volume can be adjusted, leads to a perfect match for customized reconstruction of complex defects.
