Objective　To explore effects of anastomosis of arteries and veins on blood backflow after finger replantation.　Methods　Distal end of the nondominat side finger artery of amputated finger were anastomosed with the proximal end of the palmar digital veins or finger lateral vein for treating 18patients with distal segment severed fingers. In which, 11 cases received anastomosis of finger artery and palmar digital vein, 7 cases received anastomosis of finger artery and finger lateral vein.　Results　Replanted fingers survived well for 16 patients, however, finger necrosis appeared in 1 case, and partial necrosis in 1 case.　Conclusions　Arterio-venous anastomosis is effective method for treating amputated fingers.
