Purpose
The purpose of this study was to evaluate the survival after major lower-limb amputation, at a level either below (BKA) or above (AKA) the knee, in diabetic patients.
Methods
A total of 140 diabetic patients who underwent major lower-limb amputation during the period of 2001–2011 were enrolled in the study. The patients were grouped as below-knee and above-knee amputations. The differences in survival by age, gender, amputation level and revision surgery were investigated. The clinical follow-up periods and the results of the patients with major lower-limb amputation were retrospectively assessed.
Results
The mean follow-up period was 24.87 months (range 0.06–120 months). The mortality rate of series was 32.8 % for 1 year and 70 % for 5 years. One-year mortality rate was 24.6 % and 5-year mortality rate was 66.3 % in below-knee group, 1-year mortality rate was 43.3 % and 5-year mortality rate was 83.3 % in above-knee group. The difference between mortality rates of these groups was significant (p: 0.019). There was no statistically significant difference according to age and gender (p: 0.543 and 0.568). The previous minor amputations were found to have no effect on mortality (p: 0.471).
Conclusion
Routine utilization of diabetes follow-up, screening and treatment programs with a multidisciplinary approach might be mandatory to handle early multisystem involvement—prevent major amputation, and increase survival rate in diabetic patients.
