Reconstruction of lower leg burns with achilles tendon and tibial exposure using posterior tibial artery perforator flap: A report of six cases
Nội dung chính của bài viết
Tóm tắt
Background: Deep burns of the lower leg and ankle caused by motorcycle exhausts frequently lead to exposure of tendon or bone, where skin grafts alone are insufficient. The posterior tibial artery perforator (PTAP) flap provides reliable vascularized tissue with minimal donor morbidity and may be a valuable reconstructive option.
Methods: From June 2023 to September 2025, six patients with full-thickness lower leg burns and exposed Achilles tendon and tibia, underwent reconstruction with PTAP flaps at the National Burn Hospital, Hanoi. Flaps were designed with hand-held Doppler-guided perforator mapping. Clinical outcomes were evaluated with regard to flap survival, donor site management, and complications.
Results: Defect sizes ranged from 4 × 4 cm to 12 × 8 cm, with flap dimensions ranged from 9 × 5 cm to 16 × 10 cm and rotation arcs of 1100 - 1800. Donor sites were closed with split-thickness skin grafts. Four flaps survived completely, while two developed partial necrosis that healed after secondary intervention. No total flap loss occurred. All patients achieved stable coverage, maintained limb function, and reported satisfactory cosmetic outcomes.
Conclusion: The PTAP flap proved to be a reliable option for reconstruction of complex lower leg burns with exposure of the Achilles tendon or distal tibia
