In a prospective study, the accuracy of combined segmental pressure measurements and pulse-volume recordings was compared with Doppler waveform analysis in evaluating peripheral arterial occlusive disease. Before arteriography, 50 patients (100 limbs) underwent vascular assessment which included measurement of the segmental pressure and pulse volume at the thigh, calf and ankle. Analogue Doppler waveform tracings were obtained from the femoral, popliteal and tibial arteries and used to calculate the pulsatility index and inverse damping factor. Results of each method were assessed by independent observers and compared with the arteriographic data. No appreciable difference was demonstrated between the two methods, both giving an overall accuracy in the 90% to 95% range. Both accurately predicted the severity of iliac and superficial femoral artery obstruction and distinguished iliac from proximal disease of the superficial femoral artery. Outflow disease (tibial arteries) was better assessed by measurement of segmental pressures than by Doppler waveform analysis or pulse-volume recording alone.
在一项前瞻性研究中，将节段性压力测量与脉搏容积记录相结合的准确性与多普勒波形分析在评估外周动脉闭塞性疾病方面进行了比较。在动脉造影之前，50名患者（100条肢体）接受了血管评估，其中包括测量大腿、小腿和脚踝处的节段性压力和脉搏容积。从股动脉、腘动脉和胫动脉获取模拟多普勒波形描记图，并用于计算搏动指数和反阻尼因子。每种方法的结果由独立观察者进行评估，并与动脉造影数据进行比较。两种方法之间未显示出明显差异，总体准确率均在90%至95%范围内。两者都能准确预测髂动脉和股浅动脉阻塞的严重程度，并区分髂动脉病变与股浅动脉近端病变。与单独使用多普勒波形分析或脉搏容积记录相比，通过测量节段性压力能更好地评估流出道疾病（胫动脉）。
