Introduction: Major amputations cause a high rate of morbidity and mortality. Our objectives were to evaluate the mortality rate in the first month, and 2 and 5 years after amputation for diabetic foot and to compare the mortality rate in patients with below-theknee (BKA) and above-the-knee amputations (AKA).
Materials and Methods: Sixty patients with 64 major amputations, operated on between 2010 and 2018, were retrospectively evaluated. The following information was collected: personal data, laterality, University of Texas classification score, biochemical analysis results, Doppler studies, comorbidities, survival, and cause of death. The overall mortality rate and the mortality rate by type of amputation in the first month and after 2 and 5 years were calculated.
Results: 58 amputations were performed in men and 6 in women (37 right, 27 left), 39 were AKA and 25 were BKA. The average age was 68 years. There were 28 deaths: 15 patients with AKA and 13 with BKA. Mortality rates were: 13.33% in the first month, 33.3% after 2 years, and 46.42% after 5 years (patients with AKA, 26.78%; patients with BKA, 19.64%). The differences in the creatinine levels of the patients who died were statistically significant. The main causes of death were cardiovascular complications.
Conclusions: Mortality rates were significantly higher in patients with above-the-knee amputation. The sepsis-related mortality rate in the first month was high. Patients with kidney disease had a higher mortality rate.
