Abstract
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.
