Abstract: 【Abstract】〓Objective〓To introduce the method and experience of free thoracoumbilical flap for repairing soft tissue defect of lower extremities. Methods〓Fifteen patients (male 12 cases, female 3 cases, and aged 21-56 years old) with soft tissue defect of lower extremities were reported between 2009 and 2012, including 10 cases of traffic accident injury, 3 cases of crush injury and 2 cases of machine injury. Of 15 cases, the sites of the soft-tissue defects included shank region in 11 cases, lower leg (including internal, external malleolus) in 4 cases. The defect size was 18 cm × 13 cm in length to 28 cm × 16 cm in width. All soft tissue losses were filled with free thoraco-umbilical flap. Results〓All pedicled thoraco-umbilicus flaps survived. Vascular crisis postoperation occurred in one case due to arterial embolization in donor, and healed by autogenous vein graft. Distal part skin necrosis was found in one case and recovered after dressing change. Conclusion〓Free thoracoumbilical flap can supply a large and high quality skinflap for repairing soft tissue defect of compex extremity trauma.
