Arteries of the legs
In each segment, the doctor evaluates the wall (thickness, calcification, plaques), measures the speed of blood flow - local acceleration indicates the degree of stenosis, a change in the waveform below (main → collateral) - indicates a significant obstacle; The ankle-brachial index is often calculated (normal 0.9–1.3, decreased due to ischemia). The result determines the tactics: training walking and medications for moderate stenoses, consultation with a vascular surgeon and CT angiography for planning stenting or bypass surgery for critical ones. In diabetics, the test is performed regularly to prevent diabetic foot.

Why ultrasound
Ultrasound is a safe imaging method without radiation: suitable for children, pregnant women and for repeated monitoring. The doctor sees organs in real time, assesses their structure, size and blood flow (in Doppler mode), and a conclusion with measurements is issued immediately after the study. The information content depends on the training and experience of the specialist; In the clinics below, ultrasound examinations are performed by ultrasound diagnostic doctors using expert-class devices.
