Objective To study the effect of vein-occlusion on the replanted limb survival in SD rats at different stages. Methods Twenty-five adultSD rats were randomly divided into 5 groups according to the time of the femoral vein occlusion after the replanted limbs:2- ,3- ，4 -，6-，and 8- day groups. The limbs were observed through naked eye, measurement of dermal temperature and angiography. Results No formation of collateral veinlet was found, and necrosis wasseen in the replanted limbs of 2- , 3- day groups. Reflux-vein was gradually increased in the replanted limbs of 4，6，and 8 day groups. Angiographic score of capillary density and dermal temperaturein the thigh muscles were greater in groups 4-，6-，and 8- day than in groups 2 and 3 day. Conclusion Within 2 and 3 days，the replanted limbs of SD rats will necrose because of vein-occlusion; and 4 days later the replanted limbs can survive depending on the reflux-vein of new collateral veinlet.
