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.
