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.
1984年1月至1986年6月，共进行了621次下肢动脉双功扫描。54.8%的检查是出于临床原因进行的。45.2%的检查指征是严格的科研目的。在进行双功扫描之前，先进行了包括脉搏容积记录和多普勒压力测量在内的临床及非侵入性检查。分析表明，对于存在局限性狭窄和短段闭塞且有可能进行导管治疗的患者，双功扫描可以替代动脉造影。对于狭窄不明显或长段闭塞的患者，可以选择不进行动脉造影而采取保守治疗。
