Blood bridge venous flap to repair finger wound with proper palmar digital artery defect / 中华显微外科杂志

ABSTRACT

Objective To explore the application and clinical effect of blood bridge venous flap in finger wound with proper palmar digital artery defect. Methods From February,2007 to September,2016,11 cases of fin-ger wound with artery defect were repaired with forearm vein free flap by the way of bridging blood vessels. The time from injury to surgery was 1.5 to 6 hours(average 2.5 hours).Vascular defect length was 1.4 to 3.4 cm(average 2.3 cm). 8 cases were bridged the unilateral digital artery and 3 cases were bridged the both side. The area of skin flap was 1.5 cm × 2.0 cm to 2.2 cm × 3.5 cm and the donor site was sutured directly. Results One case appeared necrosis in marginal part and healed after dressing change. The other flaps and finger survived and the incisions healed well.All the 11 cases were followed up after operation. The follow-up time ranged from 6 to 20 months, aver-aged 10 months. The color and texture were well,the sensation of temperature, pain and tactile were recovered, and the flap had good contour. According to TAM system evaluation method: 6 cases got excellent results,4 cases were good,1 case was poor. The donor site only had a linear scar and the flexion and extension of wrist were not limited. Conclusion Flow bridging venous flap can reconstruct the finger blood and repair the wound simultaneously. To the finger with nerve or tendon defect,bridged with the cutaneous nerve or palmaris longus tendon can also get satisfactory result.
