Impedance plethysmographic observations have been correlated with aortographic observations in 57 patients suspected of aortic occlusive diseases. Aortic occlusions have been characterised by marked decrease in blood flow index and significant increase in differential pulse arrival time at thigh level bilaterally. Atherosclerotic affection of the aorta has been featured by a bilateral decrease in the value of blood flow index as well as differential pulse arrival time at thigh level. Leriche's syndrome, however, has been found to decrease the blood flow index moderately at thigh in both the legs without any significant change in differential pulse arrival time. Aortography in all the patients has confirmed the diagnosis made by impedance plethysmography.
对57例疑似主动脉闭塞性疾病的患者进行了阻抗体积描记观察，并与主动脉造影观察结果进行了对比。主动脉闭塞的特征是血流指数显著降低，双侧大腿水平的脉搏到达时间差显著增加。主动脉粥样硬化的特点是双侧大腿水平的血流指数值以及脉搏到达时间差降低。然而，发现勒里什综合征会使双腿大腿的血流指数适度降低，而脉搏到达时间差没有任何显著变化。所有患者的主动脉造影均证实了阻抗体积描记法做出的诊断。
