A non invasive method for the diagnosis of occlusive diseases of the peripheral arteries and the follow-up of therapy is proposed. The method consists in the performance of an isometric effort of the inferior limbs and the Doppler detection of the dorsalis pedis systolic pressure. 41 patients with different degrees of peripheral artery involvement have been studied and the results compared with those obtained in a control group of 12 normal subjects, equally matched for ages and sex. In the normal subjects the maximal dorsiflection of the feet for 30 seconds caused a mean increase of the heart rate of 20% and no changes of the systolic blood pressure. In the patients with peripheral artery disease the isometric effort caused, contemporary to the increase of the heart rate, a decrease of the dorsalis pedis systolic pressure, that varied from 15 to 100% according to the degree of the arterial involvement. A close correlation was found between the degree of the percent reduction of peripheral systolic pressure and the entity of the arterial involvement, as evidenced by other invasive and non-invasive methods. The method proposed appears useful for a proper diagnosis of peripheral vascular diseases in those patients who cannot undergo invasive investigations or the treadmill effort test.
本文提出了一种用于诊断外周动脉闭塞性疾病及监测治疗效果的非侵入性方法。该方法包括让下肢进行等长运动，并通过多普勒检测足背动脉收缩压。对41例不同程度外周动脉受累的患者进行了研究，并将结果与12名年龄和性别匹配的正常受试者组成的对照组进行比较。在正常受试者中，足部最大背屈30秒会使心率平均增加20%，收缩压无变化。在外周动脉疾病患者中，等长运动在心率增加的同时，会导致足背动脉收缩压下降，根据动脉受累程度，下降幅度在15%至100%之间。外周收缩压降低百分比的程度与动脉受累程度之间存在密切相关性，这已被其他侵入性和非侵入性方法所证实。所提出的方法对于那些无法进行侵入性检查或跑步机运动试验的患者进行外周血管疾病的准确诊断似乎很有用。
