Repair soft tissue defects of extremities with the perforator flap based on the first perforating artery of Profunda artery / 中华整形外科杂志

ABSTRACT

Objective@#To investigate the feasibility of repairing soft tissue defects of extremities with the perforator flap based on the first perforating artery of profunda artery.@*Methods@#From January 2015 to December 2018, 9 patients with soft tissue defects of extremities were treated in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University. 5 males and 4 females; aged 29-48 years, average 36 years old. The causes of injury were traffic accident injury (4 cases), heavy object crush injury (3 cases) and mechanical injury (2 cases). There were 3 cases of soft tissue defect of upper limb, 6 cases of soft tissue defect of lower extremity, 2 cases of tendon and nerve rupture, 2 cases of fracture, 1 case of tendon and 1 case of bone exposure. All soft tissue defects were repaired with the perforator flap based on the first perforating artery of Profunda artery. After debridement, The range of soft tissue defect was 10 cm×5 cm-16 cm×10 cm. The intraoperative flap area was 12 cm×6 cm-18 cm×11 cm. The vascular anastomosis was performed in the area, the flap covered the wound surface and the donor site directly pulled the suture or grafted skin.@*Results@#All flaps survived completely and there were no complications such as vascular crisis. Follow-ups were performed in various forms for 6 to 12 months. These flaps were satisfactory in appearance and function and had a good texture.@*Conclusions@#The perforator flap based on the first perforating artery of profunda artery can repair the defects of the limbs in the soft group. The donor site of the flap is hidden, the amount of tissue available is relatively large and the repair effect is good.
