Abstract
The purpose of this study was to evaluate the factors which may influence survival rate of replantation. We have performed replantation of 47 amputated digits from 1991 to 1996. Patients included 19 men and 10 women, ranging from 18 to 64 years of age, with a mean of 45.1 years. Survival rate was 78% in 27 completely amputated digits and 80% in 20 incompletely amputated digits and overall average rate of survival rate was 79%. We reviewed all replanted digits with regard to factors which influenced survival rate. The age, ischemic time, amputated level didn't influence the survival rate. The survival rate of multiple amputated digits was inferior to that of single amputated digit. The survival rate of avulsion type was inferior to that of clean-cut type, local crushed type and diffuse crushed type. In the correlation between the number of anastomosed vessels and the survival rate, it shows low rate of survival by anastomosis of 1 artery and 1 vein. In order to increase the survival rate of replantation, we recommend that arterial anastomosis is 2 arteries and venous anastomosis is more than 2 veins.
