Abstract: Objective　To explore the operative method of improving the survival of arterialized venous flap.    Methods    Ditching  was made between the double dry veins, the adipose layer was cut into the subdermal vascular network, and the traffic branch fracture between the double dry veins was ligated. According to the size of the flap, selective ligation of the arterial vein branch  was carried out to control the amount of blood supply from the skin flap to make the blood supply uniform.   Results    In the group, there were 48 flaps and 25 cases were ruddy after operation. A small amount of scattered blisters occurred in 16 cases, and congestion and swelling occurred in 7 cases 3~7 days after operation. All 48 flaps survived,  the excellent and good rate was 85% (41 cases).   Conclusions    The survival quality of arterialized venous clap by the double modified design is further improved, which has the significance of clinical application.
