Objectives: To evaluate the results of reconstruction of leg defects using pedicled perforator flaps. Subjects and methods: This is a retrospective and prospective study on 55 patients who were treated for leg defects with the perforator flaps at 108 Military Central Hospital from March 2011 to December 2018. Results: The defect sizes were in the range of 2 x 3 cm to 6 x 14 cm. Total flap necrosis occurred in 1 patient (1.8%), 1 patient (1.8%) developed partial flap necrosis > 50%, 11 patients (20%) developed partial flap necrosis < 50%, and 42 patients had flaps completely survived (76.4%); donor site was closed primarily in 19 patients (34.5%) and small skin graft was performed in 36 patients (65.5%). The flap was based on a single perforator of the anterior tibial, posterior tibial, and peroneal arteries rotated up to 180 degrees. Operating time was from 90 to 150 minutes. Rest of the flaps survived well with good aesthetic results. Conclusion: Surgical reconstruction of leg defects using pedicled perforator flap is safe and reliable. The technique is convenient, less time consuming, and minimal donor site morbidity. It provides anesthetically good results. * Keywords: Perforator flap; Propeller flap; Leg defects; Surgical reconstruction.
