One hundred lower extremities were evaluated by measurement of common femoral intra-arterial pressure and high-thigh Doppler-derived segmental pressures using wide and narrow blood pressure cuffs to assess the accuracy of high-thigh pressures in the evaluation of aortoiliac disease. Sixty-four extremities were also studied by arteriography. The results were analyzed using the common femoral intra-arterial pressure as the standard. The accuracy was poor for both the wide (52%) and narrow (73%) cuff techniques. No significant differences between the two techniques were evident in regard to the incidence of false positive (wide cuff, 75%; narrow cuff, 65%) and false negative (wide cuff, 3%; narrow cuff, 8%) tests. Superficial femoral artery disease was found to be responsible for all false positive tests using the narrow cuff technique (20 of 20) and all but one of the false positive tests using the wide cuff technique (34 of 35). These data indicate that segmental high-thigh pressures are useful primarily as a screening technique (low false negative rate) to exclude hemodynamically significant aortoiliac occlusive disease at rest.
通过使用宽、窄血压袖带测量股总动脉内压力和大腿高位多普勒衍生的节段性压力，对100条下肢进行评估，以评估大腿高位压力在评估主髂动脉疾病中的准确性。还对64条下肢进行了动脉造影研究。以股总动脉内压力作为标准对结果进行分析。宽袖带技术（52%）和窄袖带技术（73%）的准确性均较差。两种技术在假阳性（宽袖带，75%；窄袖带，65%）和假阴性（宽袖带，3%；窄袖带，8%）检测的发生率方面没有明显差异。发现股浅动脉疾病是窄袖带技术所有假阳性检测（20例中的20例）以及宽袖带技术除1例之外的所有假阳性检测（35例中的34例）的原因。这些数据表明，节段性大腿高位压力主要作为一种筛查技术（假阴性率低），用于排除静息时具有血流动力学意义的主髂动脉闭塞性疾病。
