[Clinical application of perforator flap in repairing soft tissue defects of extremities].

OBJECTIVE

To investigate the method and effectiveness of perforator flaps in repairing soft tissue defects of extremities.

METHODS

Between June 2002 and December 2009, 81 patients with soft tissue defect of extremities were treated. There were 69 males and 12 females with an average age of 54 years (range, 13-75 years). Defect causes were injury in 35 cases (the disease duration ranged from 1 hour to 45 days), tumor resection in 19 cases, and scar resection in 27 cases. The defect located at limb and foot in 56 cases, forearm and hand in 25 cases. The defect size ranged from 3 cm x 3 cm to 23 cm x 18 cm. The perforator flaps included the peroneal artery perforator flap in 26 cases, the radial artery perforator flap in 18 cases, the medial plantar artery perforator flap in 18 cases, and the lateral circumflex femoral artery perforator flap in 19 cases. The flap size ranged from 4 cm x 3 cm to 25 cm x 18 cm. The donor site was sutured directly or repaired by free skin graft.

RESULTS

Partial necrosis of the flaps occurred in 4 cases at 3-7 days after operation, then the flap survived after expectant treatment. The other flaps and free skin grafts survived successfully, and the incisions healed by first intention. All patients were followed up 1 to 16 months with an average of 9 months. The appearance, texture, and colour of the flaps were similar to those of the donor site.

CONCLUSION

It is an effective method to use the perforator flap for repairing soft tissue defect of the extremities.
