|
|
Purpose: The authors evaluated the clinical results and prognosis after amputating the lower extremity due to diabetic foot.
Materials and Methods: From 1991 to 2003, the patients who had suffered amputation of his lower extremity due to diabetic foot ulcer were evaluated retrospectively. 79 patients were male and 6 patients were female. The author evaluated the patient who had the ipsilateral additional surgery, contralateral amputation, level of blood sugar, combined disease and mortality rate within 5 years from medical record. Statistical analysis was done by Chi-square test and Kaplan-Meier survival test.
Results: Mean age of patients who had first experienced amputation was 63.4 years old. The mean duration of diabetes until amputation was years. Major amputations were 50 cases and minor amputations 35 cases. 20 patients (23.5%) were suffered ipsilateral secondary surgery including revised stump. Overall 5-year mortality rate was 18.8% (16 cases). Death rate within 1 year was 8.2% (7 cases), mortality rate within 3 years was 14.1% (12 cases). 5-year mortality rate after major amputation was 20% (10 cases) and after minor amputation was 17.1% (6 cases). It was statistically significant (p<0.05). Patient who underwent more than 2 combined vascular related disease had higher mortality rate than diabetic amputee without combined disease (p<0.05).
Conclusion: Mortality rate after major amputation was significant higher than amputation after minor amputation in diabetic patients from our data.
