Abstract:
To evaluate the surgical technique and clinical effect of applying Flow-through flap pedicled with superficial palmar branch of radial artery for bridging finger replantation complex defect of soft tissue and vessel. Methods From February, 2013 to March, 2018, 9 cases of severed fingers composited defect of soft tissue and vessel were treated with Flow-through flap pedicled with superficial palmar branch of radial artery.The flap was designed from the proximal end of rasceta and the donor sites were sutured directly. The size of flaps was 3.0 cm ×1.5 cm-4.0 cm×2.2 cm. The superficial branch of the radial artery in the flap was used to bridge the finger artery. And the vein of proximal and distal ends in the finger was bridged by the subcutaneous vein. The proper palmar digi-tal nerve defect was bridged by palm skin graft of median nerve. The appearance, feeling and joint function of fingers was followed-up regularly after operation. Results All transfering flaps survived and all cases were followed-up for 7 to 33 months. The donor sites got primary healing with straight scars. The appearance and texture of the flaps were satisfactory. Two-point discrimination ranged from 8 to 11 mm. The pain sensation, warmth sensation and touch sen-sation of the flaps got better. And the appearance and functions of severed fingers recovered well. Conclusion The Flow-through flap pedicled with superficial palmar branch of radial artery is easy to harvest and anastomose, which is masked and a small incision for the donor site. It is an ideal method for bridging severed fingers and repairing of fin-ger wound.
