Objective To explore the feasibility and effectiveness of free transplantation of medial plantar Flow-through venous flap for primary repairing children’s finger wounds with digital artery defect.Methods Between July 2016 and October 2020, 9 children who suffered finger wounds with digital artery defect were primary repaired with free transplantation of medial plantar Flow-through venous flap. There were 6 boys and 3 girls, with an average age of 6.8 years (range, 4-13 years). The defects were caused by heavy weight puncture injury in 5 cases and strangulation injury in 4 cases. Among them, there were 3 cases of index finger wounds, 3 cases of middle finger wounds, 2 cases of ring finger wounds, and 1 case of little finger wounds. The wound area ranged from 1.8 cm×1.5 cm to 4.0 cm×2.5 cm. The time from injury to operation was 1.3-8.6 hours, with an average of 4.8 hours. The flap area ranged from 2.0 cm×1.6 cm to 4.2 cm×2.6 cm. After the flaps were inverted, the veins were used to bridge the finger arteries while repairing the wounds. The donor site of the foot was sutured directly in 4 cases, and repaired with full-thickness skin grafts in 5 cases.Results All flaps survived, and hand wounds healed by first intention; 8 cases of foot donor site wounds healed by first intention, and 1 case had partial necrosis in the marginal area of the skin graft, which healed after dressing change. All 9 children were followed up 3-24 months, with an average of 9 months. The color and texture of the flap were similar to those of the surrounding normal skin, and the protective feeling was restored. The two-point discrimination of the flap was 7-10 mm, with an average of 8 mm. At last follow-up, according to the upper limb function evaluation standard of Hand Surgery Society of Chinese Medical Association, the finger function was excellent in 5 cases and good in 4 cases. There was no ulcer formation and scar hyperplasia in the foot donor site, which did not affect walking.Conclusion The free transplantation of medial plantar Flow-through venous flap is an ideal repair method for repairing children’s finger wounds with digital artery defect. It has the advantages of simple flap extraction, thin flap, similar color and texture to the skin of the hand, and concealed donor site.
