Abstract：Objective To study the role of superficial venous trunks in the venous drainage of reverse-flow flaps.Methods Three groups of reverse-flow flaps were designed in rabbit ears.Flaps of group A contained the marginal venous trunks;Flaps of group B contained the central arterial and venous trunks;Flaps of group C contained no superficial venous trunks.Through transparent chambers of rabbit ears,microvenous diameters, blood speed or blood state were measured preoperatively and at 5,10,15,30,60,120 minutes postoperatively. The survival rate of flaps was calculated on day 7 postoperatively. Results The microvenous diameters of group A were less than group B and C. The falp survival rates and blood speed or state of group A were also better than those in group B and C.Conclusion Superficial venous trunks can promote the venous drainage of reverse-flow flaps,reduce venous stasis and enhance the survival rate of flaps.
