Duplex scanning is becoming increasingly important in the diagnosis and follow-up of arterial lesions, though most surgeons and radiologists currently still prefer diagnostic angiography prior to percutaneous transluminal angioplasty (PTA). We performed PTA based on Duplex scanning alone in 31 selected patients during the last 6 months of 1991. Seventeen patients were treated for lower extremity ischemia and 14 for (a)-symptomatic stenosis in a peripheral bypass. Results of Duplex scanning were compared to the finding of PTA to assess the value of Duplex scanning done prior to PTA. Duplex scanning showed 51 lesions eligible for PTA, in 48 of 51 lesions (94%) the location as found with Duplex scanning was in agreement with the findings of the angiogram during PTA. Of a total of 31 patients scheduled for PTA, Duplex scanning predicted the indication for PTA adequately in 26 patients (84%). No complications were seen. Duplex scanning proved to be a valuable tool in the detection of lesions suitable for PTA. Furthermore, puncture site and route can be determined by means of Duplex scanning.
双功扫描在动脉病变的诊断和随访中变得越来越重要，尽管目前大多数外科医生和放射科医生在经皮腔内血管成形术（PTA）之前仍更喜欢诊断性血管造影。在1991年的最后6个月里，我们仅根据双功扫描对31例选定的患者进行了PTA。17例患者因下肢缺血接受治疗，14例因外周旁路术中无症状性狭窄接受治疗。将双功扫描的结果与PTA的发现进行比较，以评估PTA前进行双功扫描的价值。双功扫描显示51处病变适合进行PTA，在51处病变中的48处（94%），双功扫描发现的位置与PTA期间血管造影的结果一致。在总共31例计划进行PTA的患者中，双功扫描在26例患者（84%）中充分预测了PTA的指征。未观察到并发症。双功扫描被证明是检测适合PTA的病变的有价值工具。此外，穿刺部位和路径可以通过双功扫描来确定。
