[Duplex sonography in the diagnosis of ischemic disease of the lower extremity. Comparative study with angiography]

The aim was to study possibilities of duplex sonography in evaluation of ischemic diseases of the lower extremities. The results obtained were compared with angiographic findings and high correlation of the results was obtained. Duplex sonography is a simple, safe, noninvasive method in diagnosing the site and degree of stenotic changes on the arteries of the lower extremities.
