Repair of diabetic foot ulcer wound by anterolateral thigh chimeric perforator flap / 中华显微外科杂志

ABSTRACT

Objective:To investigate the clinical effect of the anterolateral thigh perforator chimeric flap in the treatment of the wound of diabetic foot ulcer (DFU) .Methods:From January, 2018 to December, 2019, 14 cases wound of DFU of type II diabetic were treated by anterolateral thigh chimeric perforator flap. The patients were 10 males and 4 females, at 49 to 58 years old. Of the 14 patients, 10 with simple peripheral neuropathy, 4 with peripheral neuropathy complicated with vascular disease, and none with single vascular disease. With strict control of patients' blood glucose, antibiotics blended bone cement was applied or filled onto grade 2 or higher grade Wagner's DFU after debridement. In addition, the anterolateral thigh chimeric perforator flap was transferred 2 to 3 weeks later. The size of flap was 8 cm×3 cm-27 cm×7 cm. Regular followed-up were made after surgery.Results:Thirteen flaps survived in one stage after surgery. The other 1 flap had venous vascular crisis, and survived completely after active exploration. The patients were followed-up for 6-12 months. All the flaps survived well in good shape and texture. The donor and recipient areas healed well. The functional recoveries of the DF were satisfactory.Conclusion:Application of anterolateral thigh perforator chimeric flap in repair of the refractory wound of DF achieves a good clinical outcome and effectively improves the life quality of patients.
