Aortoiliac duplex scanning, while accurate, is time-consuming and technically demanding. This study aimed to develop a fast, non-invasive screening test for aortoiliac disease. Colour duplex scanning was used to record common femoral Doppler ultrasonographic waveforms following 3 min of arterial occlusion using a thigh cuff in 25 patients with normal aortoiliac segments and 25 patients with significant aortoiliac disease. The latter patients had a prolonged period of postocclusive hyperaemic flow compared with the former. End diastolic velocity, 70 s after cuff release, was a significant discriminant between the two groups (sensitivity of 88 per cent, accuracy of 92 per cent). The postocclusive hyperaemic duplex (PHD) test performed well when used prospectively in a further 50 limbs (sensitivity of 86 per cent, accuracy of 84 per cent). The test was more sensitive than femoral pulse palpation and compared favourably with arteriography. The PHD test provides a simple, noninvasive assessment for aortoiliac disease that can be performed on the initial outpatient clinic visit.
腹主动脉-髂动脉双功扫描虽然准确，但耗时且对技术要求高。本研究旨在开发一种快速、无创的腹主动脉-髂动脉疾病筛查试验。对25例腹主动脉-髂动脉段正常的患者和25例患有严重腹主动脉-髂动脉疾病的患者，使用大腿袖带阻断动脉3分钟后，用彩色双功扫描记录股总动脉的多普勒超声波形。与前者相比，后者的闭塞后充血血流持续时间更长。袖带松开70秒后的舒张末期速度是两组之间的显著判别指标（敏感性为88%，准确性为92%）。当对另外50条肢体进行前瞻性应用时，闭塞后充血双功（PHD）试验表现良好（敏感性为86%，准确性为84%）。该试验比股动脉搏动触诊更敏感，与动脉造影相比也更具优势。PHD试验为腹主动脉-髂动脉疾病提供了一种简单、无创的评估方法，可在首次门诊就诊时进行。
