In replantation surgery, an attempt is made to repair as many vessels as possible. However, operative procedures might be simplified to reduce the operative time and the number of personnel required. In an attempt to determine the essential number of vascular anastomoses in finger replantation, the correlation between the number of anastomosed vessels and survival rates, and survival rates according to the anastomosed artery-vein ratio were examined in 154 replanted fingers that had been completely amputated, especially in the Zone 11 and Zone III. Digits with two arteries repaired had higher survival rates than those with only one artery repaired; however, there was no significant difference between survival rates and the number of arterial anastomoses in any of the zones, but significant difference in the view of the sum of the Zones. The number of anastomosed veins was well-correlated statistically with the survival rate. A statistical significant difference between the survival rates with one venous anastomosis and two or three venous anastomoses was observed only in Zone III (middle phalangeal region). These results support the following conclusions: 1) The essential amount of arterial repair appears to be one arterial anastomosis. 2) The number venous repair appears to be more than artery especially at Zone III, statistical significancy is present among the number of venous repair. 3) When two artery is repaid at Zone III, salvage procedure is not effective, and so one or more arterial repair must be required.
