Aims: Transfemoral amputation (TFA) is associated with a high postoperative mortality though it is unclear whether diabetes is associated with an increased mortality or not. The aim was to examine mortality at 1 week and 1 year after first-ever TFA with special reference to diabetes.
Methods: We included 162 first-ever TFAs from 1996 to 2012. Mortality data were collected with the use of the Swedish personal identification number.
Results: The median age was 85 years. Diabetes mellitus were present in 19% (n = 30) of the patients and 67% (n = 109) had cardiovascular disease. Mortality was significantly higher for patients with diabetes compared to patients without diabetes at 1 week (30% vs. 8%, p = 0.001) and at 1 year (80% vs. 57%, p = 0.02). This difference was significant in multivariable analysis.
Conclusions: We conclude that postoperative mortality was high. The high mortality rate emphasizes the need for early and adequate evaluation of every patient́s overall condition and whether amputation is beneficial or not. Although further studies are needed to analyze the specific causes of early death in amputees and we suggest close monitoring of blood-sugar in patients with diabetes and early treatment of infections and cardiac events in all patients.
