Data is provided to demonstrate the reliability of measuring the systolic pressure index (SPI) for surveillance of lower limb arteriopathy (mainly during postoperative follow-up), the aim being to establish a simple, rapid and reliable surveillance test of high decisional value. Reproducibility of SPI values was studied in two series of patients (personal and collective) and on variations of SPI before and after reconstructive arterial surgery, as well as in cases of arterial bypass degradation. The following threshold values, beacon of the surveillance, were retained: --variations of 15% in relation to a reference examination: non-significant, --variations of 20 to 30%: probably significant, --variations of more than 30%: significant. A drop of 30% or more of the SPI in relation to a postoperative reference value during surveillance after reconstructive arterial surgery suggests the need for a follow-up angiography to detect possible lesions that could affect bypass permeability, whatever the patient's symptomatology.
提供数据以证明测量收缩压指数（SPI）用于监测下肢动脉病变（主要在术后随访期间）的可靠性，目的是建立一种具有高决策价值的简单、快速且可靠的监测测试。在两组患者（个人和集体）中研究了SPI值的可重复性，以及重建动脉手术后SPI的变化，以及动脉搭桥退化的情况。保留了以下作为监测指标的阈值：——相对于参考检查变化15%：无显著意义，——变化20%至30%：可能有显著意义，——变化超过30%：有显著意义。在重建动脉手术后的监测期间，若SPI相对于术后参考值下降30%或更多，则表明无论患者症状如何，都需要进行后续血管造影以检测可能影响搭桥通畅性的病变。
