Abstract

Background: Patients with chronic limb threatening ischemia (CLTI) of the lower limbs (LL) undergo arteriography for revascularization surgery planning. Doppler ultrasound (DU) is non-invasive and can provide information about the distal arteries through measurement of the resistance index (RI).

Objectives: To correlate the Rutherford Angiographic Classification with the RI for assessment of the distal arterial bed of the LL.

Methods: A cross-sectional study, conducted at a public tertiary hospital with 120 patients with LL CLTI, from September 2019 to April 2022. The RI of arteries that were candidates for revascularization was compared with the images of the same arteries obtained using arteriography, using the Rutherford Angiographic Classification of the distal bed.

Results: A total of 120 LL were assessed in 120 patients with a mean age of 68.6 years. The sample was 50.0% male and 90.0% of the patients in the sample were classified as Rutherford category five. The RI values found for the arteries of the leg exhibited a statistically significant positive correlation with the Rutherford Classification (anterior tibial, p< 0.01; posterior tibial, p = 0.012 fibular, p = 0.034; and dorsalis pedis, p < 0.001).

Conclusions: In this study, RIs for the arteries of the leg measured using Doppler ultrasound exhibited a positive correlation with the Rutherford Classification. This index could be useful for assessment of the distal arterial bed of the lower limbs of patients with chronic limb threatening ischemia.

血管阻力指数与动脉造影术在评估慢性肢体威胁性缺血远端动脉床方面的相关性。

背景：下肢（LL）慢性肢体缺血（CLTI）患者需要接受动脉造影检查，以制定血管重建手术计划。多普勒超声（DU）是一种无创检查，可通过测量阻力指数（RI）提供有关远端动脉的信息：将卢瑟福血管造影分类与 RI 相关联，以评估 LL 远端动脉床：一项横断面研究，于2019年9月至2022年4月在一家公立三甲医院进行，共收治120名LL CLTI患者。采用卢瑟福远端动脉床血管造影分类法，将作为血管重建候选者的动脉的 RI 与使用动脉造影术获得的相同动脉的图像进行比较：共对 120 名患者的 120 条 LL 进行了评估，这些患者的平均年龄为 68.6 岁。样本中男性占 50.0%，90.0% 的患者被划分为卢瑟福五类。腿部动脉的 RI 值与卢瑟福分类有显著的统计学正相关（胫骨前动脉，p< 0.01；胫骨后动脉，p = 0.012 腓骨动脉，p = 0.034；足背动脉，p < 0.001）：在这项研究中，使用多普勒超声测量的腿部动脉RI与卢瑟福分类法呈正相关。该指数可用于评估慢性肢体威胁性缺血患者的下肢远端动脉床。
