Abstract:
To investigate the clinical effect of repairing the electrical wound of upper limbs by using the perforator flap pedicled with the descending branch of lateral circumflex femoral artery. Methods From August, 2014 to July, 2018, the perforator flap pedicled with the descending branch of lateral circumflex femoral artery was used to repair the electrical wound of the upper limbs in 10 cases (11 sides), which were 9 cases (10 sides) in males, 1 case (1 side) in female. Three cases in the left side, 6 cases in the right side, and 1 case in both sides. The area of the flap was 12 cm ×6 cm-26 cm×11 cm.The arterial, venous and cutaneous nerves of the perforator flap were anastomosed with those of the recipient area, respectively. The patients were followed-up in outpatient depat-ment, including flap survival, texture, appearance, sensory recovery, donor site healing and scar hyperplasia. Results All the flaps survived without vascular crisis. Infection occurred in 1 case (1 side). The wound was healed 19 d after the operation by using effective antibiotics and dressing change. All cases were followed-up for 4-24 months after the operation. The blood supply of the flaps was good, the texture was similar to that of the recipient area, and the ap-pearance was satisfactory. There was no obvious bloat, and no ulceration of the flap was found. The anterolateral femoral cutaneous nerve was retained in the flap and anastomosed with the cutaneous nerve in the recipient area. The sensory recover to S3 in 3 flaps, S2 in 7 flaps, S1 in 1 flap. The donor site of the flap was sewn up with aesthetic treat-ment.After the operation, the donor sites presented a linear scar with a concealed position and no occurrence of oste-ofascial compartment syndrome. Conclusion The perforator flap pedicled with the descending branch of lateral cir-cumflex femoral artery has a constant anatomical position of perforator vessel, a wide excision range, abundant blood supply, a good appearance and a hidden donor site, which is a good choice for repairing the electrical wound.
