Abstract

Abstract:

Objective To explore the effectiveness of veno-arterialization of finger lateral vein for repairing severed finger tips by comparing with veno-arterialization of finger pulp vein. Methods From March 2006 to April 2012, thirty-four patients with severed finger tips were admitted to our center, with veno-arterialization after failure in anastomosing artery of finger over times. Twenty patients underwent veno-arterialization of finger lateral vein(20 fingers, trial group). During operation, the digital artery proximal end and the finger lateral vein distal end was anastomosed as the route of blood supply. Fourteen patients underwent veno-arterialization of finger pulp vein(14 fingers, control group), the digital artery proximal end and the finger pulp vein distal end were anastomosed as the route of blood supply. There was no significant difference in gender, age, cause of injury, duration of disease, finger of injury, lesion segments, failure in anastomosing artery of finger over times, fracture, and nerve damage between 2 groups(P>0.05). Results All patients survived completely in trial group, the survival rate was 100%(20/20); Four fingers necrosis in control group, the survival rates was 71.4%(10/14); there were significant difference in results between 2 groups(P=0.022). Twenty seven patients were successfully followed up, eighteen patients were successfully followed up 6-14 months(mean, 10.2 months) in trial group, 9 patients were successfully followed up 8-12 months(mean, 9.6 months) in control group. The fingers had satisfactory appearance, finger pulp was plump with good flexibility, no obvious deformed growth of nail were found, and a sound recovery was obtained in trial group; mild atrophy of the fingers in control group. The postoperative length of nail, motion of distal interphalangeal joint(DIPJ), sensation measurement, and two point discrimination were improved significantly when compared with preoperative values in 2 groups(P<0.05). According to TAM scales, the results were excellent in 12 cases, good in 5 cases and fair in 1 cases, with an excellent and good rate of 94.4% in trial group, the results were excellent in 5 cases, good in 2 cases and fair in 2 cases, with an excellent and good rate of 77.8% in control group, there were no significantly improved(P=0.250). Conclusion The veno-arterialization of finger lateral vein is a valuable method for repairing severed finger tips, which can promote growth of nail, and restore motion and sensation of fingers.
