[Duplex sonography in the diagnosis of peripheral arterial circulation disorders].

From January 1984 to June 1986, 621 duplex scans of the arteries of the lower extremities were performed. 54.8% of the examinations were performed for clinical reasons. In 45.2% the indication was strictly scientific. Clinical and non-invasive examinations including pulse-volume recordings and Doppler pressure measurements preceded duplex-scanning. The analysis shows that duplex scanning may replace arteriography in patients with localized stenosis and short occlusions where catheter therapy is possible. Patients with insignificant stenosis or long occlusion may be selected for conservative treatment without arteriography.
