Methods: 30 patients with suspected lower limb vascular occlusive disease admitted to our hospital from May 2021 to January 2022 were included. The examinations received in the hospital included CTA imaging and digital subtraction angiography. The later examination results were the gold standard to evaluate the diagnostic efficacy of CTA imaging in lower limb vascular occlusive disease. Results: in this group, 27 suspected cases of lower extremity vascular diseases were confirmed by digital subtraction angiography, including 7 cases of lower extremity vascular occlusion, 20 cases of lower extremity vascular stenosis (8 cases of severe, 8 cases of moderate, 4 cases of mild), 26 cases of lower extremity vascular diseases diagnosed by CTA, 7 cases of lower extremity vascular occlusion, 19 cases of lower extremity vascular stenosis (7 cases of severe, 8 cases of moderate, 4 cases of mild). There was no statistical difference in the detection rate of disease types between the two examination methods (P > 0.05). With reference to digital subtraction angiography, the coincidence rate, specificity and sensitivity of CTA imaging in the diagnosis of lower limb vascular occlusive diseases were 96.67%, 100.00% and 96.30% respectively. Conclusion: the sensitivity and specificity of CTA in the diagnosis of lower extremity vascular occlusive disease are both high.展开更多
