Evaluation of peripheral arterial disease in type 2 diabetic patients using computed tomography angiography

Abstract

Background: Peripheral artery disease (PAD) in patients with Type 2 diabetes mellitus (T2DM) has broad characteristics and various complications. Aim: The purpose of this study is to evaluate PAD in T2DM and their association with age, gender, and the duration of T2DM. Materials and Methods: This study is a prospective cross-sectional one conducted at the radiology department in Royal Care International Hospital, Khartoum, Sudan, over 3 years. A total of one hundred and ten patients, 69 males and 41 females, were examined using MDCT. A binary logistic regression test was applied to identify independent predictors of PAD. Results: PAD in T2DM is found to be 50.91% atherosclerosis, 43.64% plaques, 29.09% stenosis, and 14.55% thrombosis (mean age 65.84 ± 9.57 years; mean duration of T2DM 29.37 ± 6.7 years). The prevalence of PAD was common in patients over 60-year-old. Atherosclerosis is significantly higher in males than females (59.4% vs. 36.6%, 95% confidence interval = 1.092–5.600, P = 0.03%). Plaques and stenosis of lower-extremity arteries were higher in males than females 44.9% vs. 41.5% and 29.0% vs. 29.3%) respectively. The incidence of thrombosis was higher in femoral arteries than lower distal arteries, and the prevalence was higher in females than males (22% vs. 10.1%, odds ratio = 2.228), respectively. Conclusion: Atherosclerosis, plaques, stenosis, and thrombosis were the most common PAD findings in patients affected with T2DM. Age, gender, and duration of diabetes, relatively risk factors associated with PAD. Thrombosis is more prevalent in the femoral artery than lower distal arteries.
