Abstract

Introduction: Patients with diabetes and PAD tend to have involvement of the more distal arteries, particularly the popliteal and tibial arteries. Currently, there are many non-invasive methods to diagnostic lower extremity arterial disease, of which computed tomography angiography is a rapid, high accuracy method widely used in clinical practice. Objective: Describe the characteristics of lesion imaging on computed tomography angiography of lower extremity arterial stenosis and occlusive in diabetes patients. Methods: This is a retrospective cross-sectional study including 48 diabetes patients with lower extremity arterial stenosis and occlusive disease that underwent CT angiography from January 2017 to June 2022, at University Medical Center HCMC. The characteristics of vascular calcification, site, number and distribution of lesions on each stage were analyzed lesions were classified according to the Trans Atlantic Inter Society Consensus (TASC II). Results: The most common location of lesions was posterial tibial arteries with 72 arteries (19.8%), followed by anterial tibial arteries with 68 arteries (18.7%) and superficial femoral arteries (16.7%). On all 3 stages, the common lesion morphology was TASC B, less common was TASC A. The number of vascular segments with calcification on the entire lower extremity artery accounts for a high proportion (86.3%), most multiple segments (85.4%). Conclusion: Stenosis and occlusive of lower extremity arterial in diabetes patients are diffuse, multi-location, tend to occur in infrapopliteal stages. Arterial calcifications are common and diffuse on 3 stages.
