Introduction: Peripheral artery disease is a public health problem. It is responsible for high morbidity and mortality rates. Computed tomography angiography is the examination of choice, especially in the context of limited resources. This study aimed to evaluate the contribution of computed tomography angiography to the diagnosis of lower limb arterial occlusive disease. Materials and Methods: This study was a cross-sectional descriptive study carried out at University Hospital Center of Professor Bocar Sidy SALL of Kati from January 1, 2023 to January 31, 2024. A 16-bar scanner was used for exams, Siemens brand equipped with an automatic injector. All cases of obliterative arterial disease of the lower limbs diagnosed during the study period were included. Data analysis was done using SPSS software. Results: A total of 52 patients with lower limb arterial disease were included among the 2747 CT scans and 83 lower limb angiograms performed, representing 1.9% of all CT scans and 62.65% of lower limb angiograms performed in the department. The average age was 52 years. Men accounted for the majority of patients (63.5%). The most common risk factor was diabetes (69.3%). Half of the patients suffered from gangrene (50%). CT angiography revealed diffuse involvement in 41.3% of cases. The lesions were stenotic in 71.2% of cases and occlusive in 28.8% of cases due to atherosclerotic plaques in 55.8% of cases, causing soft tissue necrosis in 22% of cases. Conclusion: Occlusive arterial disease of the lower limbs is relatively common. Older men are most affected. The predominant risk factor is diabetes. CT angiography is the preferred examination for management.
