RESUMO
Objective To evaluate the experience of replantation of severed finger tip and suggest a new method to replant the severed finger tip injury. Methods A total 25 cases of severed finger tip injuries on nail root level were retrospectively analysed.They were 18 males and 7 females,19～38 years old.The finger tips were completely cut down.The wound should be cleaned thoroughly under operative microscope and the cut ends of artery and nerve can be found on the wound.The important step was to dissect out all braches of the arch of the artery and ligate them but one small branch,so as to reduce the blood circulate into the finger tip.It was not necessary to joint the vein. Results Twenty-four fingers were survived,only one finger was necrosed.The course of 13 fingers were very prosperous.Twelve fingers had some cyanosis and 9 fingers turned red after a few punctures to release the venous blood and other 3 fingers should make a side incision torelease more venous blood.Then 2 fingers were survived and one finger was failured. Conclusion Only one artery should be anastomos for finger tip injury on nailroot level.No vein should be joint.But the branches of the artery arch should be ligated except one small branch.
