Abstract

Describe imaging characteristics of doppler ultrasound (DUS) and evaluate the complementary value of digital
subtraction angiography (DSA) in the diagnosis of peripheral arterial occlusive disease (PAOD) of lower extremity.
Materials and Methods: The study is a cross sectional one and was carried out at the hospital of Hue university of medicine and pharmacy. 40 patients diagnosed with PAOD of lower limbs went through arterial assessment with DUS and DSA. The image findings of both technique were used to evaluate the diagnosis accuracy of DUS and the complementary value of DSA.
Results: The sensitivity, specificity, positive predictive value and negative predictive value of DUS in PAOD 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 PAOD of lower extremities. DSA has high complementary value for DUS in the
diagnosis of PAOD of lower extremities, with the highest value at below-knee arteries.
