Abstract: Purpose: The aim of this study was to evaluate the frequency and types of complications that may occur after transtibial amputation in patients with peripheral arterial disease and the risk factors affecting them.
Methods: 87 patients who were diagnosed with peripheral vascular disease from January 2012 to January 2018 and underwent transtibial amputation were included. Complications occurring within 3months after transtibial amputation were retrospectively reviewed. For statistical analysis, logistic regression analysis was used and significant factors in the univariate analysis were used for statistical verification using multivariate analysis.
Results: 60 patients were male and 27 patients were female and average age of patients was 71.1(±11.06) years. There were 11 superficial infection or wound dehiscence of the stump site (12.6%), 17 deep infection (19.5%), 20 stump revisions (22.9%) and above-knee amputation was performed in 9 cases (10.3%). High ESR (P < 0.028) and multiple occlusion sites in 3D CT angiography (P < 0.011) were significantly associated with the rate of stump revision and chronic renal disease (P < 0.007) was independent risk factor of mortality.
Conclusions: More attention should be paid to postoperative management for the patients with chronic renal failure, preoperative high ESR and multiple stenotic lesions in 3D CT angiography.
