The purpose of this study was to review the outcome of adopting colour-coded duplex ultrasonography as the primary imaging modality in patients with symptomatic lower-limb arterial disease. Over a 12-month period 467 consecutive lower-limb duplex scans were performed of which 437 (94 per cent) were technically adequate. Of the 467 limbs, 184 (39 per cent) were managed conservatively, 230 (49 per cent) were referred for percutaneous transluminal angioplasty (PTA), 41 (9 per cent) underwent reconstructive surgery and 12 (3 per cent) required diagnostic arteriography. In patients referred for PTA there were only 22 (10 per cent) unexpected findings; there was agreement about superficial femoral artery occlusion length in 95 (89 per cent) of 107 limbs and about the presence or absence of a superficial femoral artery stump in 91 (85 per cent) of 107 cases. In patients referred for surgery there were no unexpected findings. Colour-coded duplex imaging can safely replace diagnostic arteriography in up to 97 per cent of lower limbs with arterial disease.
本研究的目的是回顾将彩色编码双功超声作为有症状下肢动脉疾病患者主要成像方式的结果。在12个月期间，连续进行了467次下肢双功扫描，其中437次（94%）技术上足够。在这467条肢体中，184条（39%）采用保守治疗，230条（49%）被转诊接受经皮腔内血管成形术（PTA），41条（9%）接受重建手术，12条（3%）需要诊断性动脉造影。在转诊接受PTA的患者中，仅有22例（10%）出现意外发现；在107条肢体中的95条（89%）中，关于股浅动脉闭塞长度存在一致意见，在107例病例中的91例（85%）中，关于股浅动脉残端的有无存在一致意见。在转诊接受手术的患者中，未出现意外发现。彩色编码双功成像在高达97%的下肢动脉疾病中可安全替代诊断性动脉造影。
