Abstract :

 Seventy–one patients of suspected peripheral arterial disease were evaluated with Color Duplex Sonography (CDS) and angiography. In 71 patients, total 53 lower limbs in 43 patients and 29 upper limbs  in 28 patients were studied with CDS and angiography. Compared to angiography, CDS revealed sensitivity of 83%,  specificity of 96%, PPV of 88%, NPV of 94% and accuracy of 92% for detection of various lesions in peripheral arterial  disease. The overall sensitivity of 85 and 66%, specificity of 96 and 99% and accuracy of 93 and 98 % was seen with  CDS scanning for detection of occlusion and >50% stenosis respectively. CDS is a rapid, non–invasive and relatively accurate modality for identification and localization of various vascular lesions in peripheral arteries. CDS can be used as  a screening modality for patients with symptomatic peripheral arterial diseases.
