Reconstruction with an Anterolateral Thigh Free Flap Following a Skin Graft from the Same Donor Site for Tissue Use Efficacy: Two Case Reports

Abstract

The coverage of extensive soft tissue defects requires several considerations, such as limited donor sites, reconstruction methods, and the outcome of functional recovery. In the cases described herein, when a significant soft tissue defect was present on an extremity, we opted for staged reconstruction. We first performed a split-thickness skin graft (STSG) to reduce the soft tissue defect, using the anterolateral thigh (ALT) as the donor site. In the second stage, the remaining soft tissue defect was reconstructed with an ALT free flap, utilizing the same lateral thigh area that had previously served as the STSG donor site. After the free flap procedure, we encountered several challenges in monitoring the ALT flap; however, all flaps ultimately survived. To the best of our knowledge, this is the first report of using an ALT free flap following STSG from the same donor site, demonstrating efficient tissue utilization. We believe this approach is beneficial for reconstructing extensive soft tissue defects, as it maximizes tissue use efficiency and reduces donor site morbidity when donor options are limited.
