ABSTRACT
Objective To explore the sluice gate technology in the control of nutrient vessel retrograde island skin flap with sural nerve small saphenous vein blood flow.Methods Totally 32 cases were divided into group A and group B,group A flap with no special treatment to the return of small saphenous vein,group B applied river gate principle,in operation around the small saphenous vein reserved suture,postoperative through a rubber band traction control flap blood circulation and skin flap swelling. Observation and comparison of two groups of skin flap necrosis.Results There had 4 cases in group A flap incomplete necrosis,the incidence rate was 25.0%,1 cases of skin flap incomplete necrosis in B group,the incidence rate was 6.2%.Conclusion The use ofsluice gate technique to control the small saphenous vein reflux of blood,relieve skin flap swelling,improve the survival rate of the flap is simple and effective.
