Abstract
Background and Aims: Diabetes mellitus associates with poor outcomes in chronic limb threatening ischemia but data on different hypoglycemic regimens and outcomes are lacking. We analyzed insulin-treated diabetes mellitus, non-insulin-treated diabetes mellitus, and patients without diabetes mellitus. Materials and Methods: All patients with peripheral artery disease and/or diabetes mellitus and infrapopliteal revascularization in the Department of Vascular Surgery, Turku University Hospital during 2007–2015 were included. Tibial atherosclerosis was categorized into crural index classes of I–IV. Results: Of the 497 patients, 180 were insulin-treated diabetes mellitus, 94 non-insulin-treated diabetes mellitus, and 223 patients without diabetes mellitus groups (diabetes mellitus 55.1%). Insulin-treated diabetes mellitus was the most ill, youngest (insulin-treated diabetes mellitus—median: 72.4, interquartile range: 64.0–79.5 versus non-insulin-treated diabetes mellitus—76.0, interquartile range: 67.9–83.6 versuspatients without diabetes mellitus—77.3, interquartile range: 68.5–83.7, p < 0.001), had the highest body mass index (insulin-treated diabetes mellitus—median: 27.7, interquartile range: 24.0–31.8 versus non-insulin-treated diabetes mellitus—26.3, interquartile range: 23.2–30.3 versus patients without diabetes mellitus—23.9, interquartile range: 21.5–26.9, p < 0.001), and Charlson comorbidity index (insulin-treated diabetes mellitus—65.6% versus non-insulin-treated diabetes mellitus—46.8% versus patients without diabetes mellitus—10.8%, p < 0.001). After endovascular revascularization, limb salvage was poorer for insulin-treated diabetes mellitus (p = 0.046) and non-insulin-treated diabetes mellitus groups (p = 0.011) compared to surgery, but not for patients without diabetes mellitus (p = 0.15). Patients with crural index IV in insulin-treated diabetes mellitus (p = 0.001) and non-insulin-treated diabetes mellitus (p = 0.013) had higher mortality after revascularization. Crural index IV was a risk factor for limb loss (hazard ratio: 1.37, 95% confidence interval: 1.08–1.74, p = 0.008). Conclusion: Limb salvage after bypass is better for insulin and non-insulin diabetics, compared to the endovascular approach. Extensive tibial atherosclerosis is an independent risk factor for limb loss. It associates with increased mortality in both insulin and non-insulin diabetics.
