Versatility of the Free ALT Flap for Upper and Lower Limbs Coverage Defects Reconstruction. A Consecutive Case Series

The anterolateral thigh free flap was expanded to establish itself as one of the most useful options for the reconstruction of defects in different locations. We present our experience with free ALT flap for functional coverage of different upper and lower limb defects. Methods: Retrospective study of cases of reconstruction in a period of 6 years. In the preoperative period, demographic variables, causes of the defect, size and location of the defect and time between the defect and surgery were analyzed. From the surgical technique, the type of anastomosis performed and the type of closure of the donor site were analyzed. Finally, during the postoperative period, the survival of the flaps and the complications of the flap and the donor site were evaluated. Results: We included 7 men and 5 women with an average age of 44 years. The defects were caused by oncological resection in 9 patients and by trauma in 3. The defect was in the upper limb in 4 cases and 8 in the lower limb. The size of the flap varied from 6 to 20 cm in length and from 3 to 12 cm in width. The survival rate of the flap was 92%, presenting failure only in one case. The donor site presented no complications. Conclusion: The anterolateral thigh free flap is a useful resource for the coverage of defects of different etiologies both in the upper limbs and in the lower limbs since its versatility allows it to adapt successfully in varied defects.
