Anterolateral thigh flap for distal lower leg reconstruction

Context. - Soft tissue defects of lower leg are still a challenge for the plastic surgeon. It should provide an effective and functional coverage with a minimal morbidity on the donor site. Free anterolateral thigh flap present in these areas many advantages over the pedicled local flaps and free muscle flaps used conventionally. We try to define its place through our experience with a bicentric retrospective study. Materials and methods. - A retrospective analysis of all cases of reconstruction of the lower leg using the free ALT flap was performed in two centers of reconstructive surgery. The characteristics of the defect and reconstructions were collected. The rate of success and complication has been reported as well as long term aesthetic and functional outcomes. Results. - Forty-one patients were reconstructed between 2008 and 2013 for post-traumatic care in 58.5% of cases. The average size of the defect was 191.4 cm(2), their location was mainly on the foot and ankle (61%) and bone exposure was most frequently found (82.9%). Success rate was 92.8%. Functional results were judged as very good and good in 75.5% of cases and aesthetic results as very good and good for 63.6% of cases. Three "lost sight'' 7.3% and 3 fails (7.3%) patients were not included in the result analysis. Conclusion. - Showing functional results at least similar to other flaps, ALT flap demonstrated its reliability and its low morbidity on the donor site. Its versatility allows adaptation to the vast majority of defects of the lower leg. (C) 2016 Elsevier Masson SAS. All rights reserved.
