Abstract:
Objective:To evaluate the clinical efficacy of a replay propeller distal perforator flap of the lateral circumflex femoral artery in reconstruction of the donor site defect left by the harvest of a free anterolateral thigh perforator flap (ALTPF).Methods:From June 2023 to June 2024, retrospective analysis of 11 patients with foot and ankle soft tissue defects were treated in the Department of Microsurgery, Sichuan Modern Hospital. The patients were 7 males and 4 females, aged 9-57 (average 28.6) years. Causes of injury were car accident (5 patients), machine crush (5 patients) and skin necrosis following a fall (1 patient). The size of soft tissue defects was 8.0 cm ×11.0 cm - 9.0 cm×14.5 cm. A reversed perforator island flap of distal descending branch of the lateral circumflex femoral artery was prepared to reconstruct the defect left at the donor site after the harvest of a free ALTPF. The ALTPFs were 8.5 cm × 11.5 cm to 9.5 cm × 15.5 cm in size, and the sizes of the perforator flap of descending branch of lateral circumflex femoral artery designed to reconstruct the donor site defects were at 5.0 cm × 9.0 cm to 6.0 cm × 12.0 cm. After the surgery, scheduled follow-ups were carried out at outpatient clinic and via telephone and WeChat reviews. Wound healing at recipient and donor sites, flap survival and functional recovery were observed.Results:All flaps survived smoothly after surgery, and the wounds in the donor and recipient sites healed primarily. No vascular compromise, wound dehiscence or significant swelling occurred. A total of 9 patients completed the 6-18 months postoperative follow-up, with an average of 11 months. Two patients lost in the follow-up. Only linear scars left in the donor sites, without significant impact on the thigh function. The colour and appearance of the flaps were natural.Conclusion:It is effective to use a distal replay flap of the descending branch of lateral circumflex femoral artery for reconstruction of the donor site defect left by the harvest of a free ALTPF.
