Abstract：Objective:To investigate the effect of different methods on reconstruction of venous return of severed fingertip. Methods:From March 2008 to February 2013,80 patients with severed fingertip were admitted to the Department of Hand Sur-gery. Among the 80 patients,38 patients underwent anastomosis of lateral veins of the finger,the ratio of artery:vein was 1:1,1:2 or 2:2,with mean proportion of 1:2;22 patients underwent anastomosis of finger pulp veins,the anastomotic ratio of artery:vein was 1:1;20 patients underwent anastomosis of one artery without anastomosis of veins,followed by bleeding from the nail bed or lateral-incision of finger. Results:All fingertips survived completely without venous obstruction in lateral veins an-astomosis group;1 9 fingers showed return obstruction,and necrosis occurred in 4 fingers in anastomosis of finger pulp veins group;return obstruction occurred in 20 fingers and necrosis occurred in 6 fingers in the group without vein anastomosis. Fifty-eight patients were followed up for 6 to 28 months. In 32 patients the appearance was satisfactory,finger pulp was plump,with-out deformity of nail in the group with anastomosis of lateral veins. Fourteen patients in finger pulp veins anastomosis group showed mild atrophy of the fingers;significant atrophy of the fingers was found in 12 patients in non-anastomosis group. The mean length of nail,mobility of distal interphalangeal j oint,two point discrimination,and sensation were better in lateral veins anastomosis group [(14.4±3.2)mm,(63±5)°,(4.6±0.4)mm,S(3.45±0.39)]. The result was significantly better than those in finger pulp veins anastomosis group [(12.5±2.3)mm,(48±3)°,(7.1±1.2)mm,S(2.57±0.42)],and in the group without vein anastomosis [(12.2±2.2)mm,(45±7)°,(7.3±0.6)mm,S(2.55±0.49);P<0.05]. There was no significant difference in length of nail,mobility of distal interphalangeal j oints,two point discrimination,and sensory measurement between the latter two groups(P>0.05).Conclusions:The anastomosis of lateral veins of the finger is a valuable method for replantation of severed fingertip,and it can avoid obstruction of venous circulation,increase survival rate of severed finger,promote growth of nail,and restore motion and sensation of fingers.
