Tóm tắt

Objectives: Describe imaging characteristics of Duplex ultrasound (DUS) and correlation with digital subtraction angiography (DSA) in the diagnosis of peripheral arterial disease (PAD) of lower extremity in type 2 diabetic patients.
Materials and Methods: cross sectional study with 40 patients diagnosed with type 2 diabetes and PAD on DUS. The image findings of both techniques were used to evaluate the diagnosis accuracy of DUS and the correlation with DSA.
Results: The sensitivity, specificity, positive predictive value and negative predictive value of DUS in PAD is 80,65%, 92,83%, 86,21% and 89,61% respectively. DSA complemented for DUS with 6,36% additional cases of >50% stenosis or complete occlusion and 5,49% cases of low flow in occlusion suspected arteries. DSA revealed an additional of 81% collaterals
in occluded arteries compared to DUS.
Conclusion: DUS has high diagnostic value in PAD of lower extremities in diabetes patients. DSA has high complementary value for DUS in the diagnosis of PAD of lower extremities, with the highest value at belowknee arteries.
