Vascular Doppler Ultrasound

Vascular Doppler ultrasound (or Doppler vascular examination) is a non-invasive imaging method that uses ultrasound to assess both the structure of blood vessels and the blood flow within them. Through the Doppler effect, it allows evaluation of blood flow velocity and direction, as well as the detection of narrowings, occlusions, or other vascular abnormalities.

At CardioPrima, vascular Doppler ultrasound is performed for both arterial and venous vessels in adults and children whenever assessment of peripheral circulation and vascular risk is required.

When vascular Doppler ultrasound is recommended

• in the presence of symptoms of impaired circulation: numbness, tingling, pain, or weakness in the limbs;
• in cases of varicose veins or venous insufficiency;
• when deep vein thrombosis is suspected;
• for evaluation of the carotid arteries and stroke risk;
• in patients with cardiovascular risk factors (hypertension, diabetes, dyslipidemia, smoking);
• when arterial stenosis or other vascular lesions are suspected;
• as a preventive screening method in high-risk patients.

How the examination is performed

• Gel is applied to the examined area, and the patient remains relaxed.
• An ultrasound probe (transducer) is moved along the vessels to visualize the vessel walls and lumen.
• Using the Doppler effect, blood flow velocity and direction are measured, and turbulences, reflux, occlusions, or other abnormalities are detected.
• Depending on the examined area (limbs, neck, abdomen, renal vessels, etc.), the procedure usually lasts about 20–40 minutes.

Information provided by vascular Doppler ultrasound

• confirmation or exclusion of arterial stenosis;
• detection of venous thrombosis and venous insufficiency;
• assessment of arterial and venous blood flow;
• evaluation of vessel wall thickness and atherosclerotic plaques;
• determination of the direction and severity of venous reflux;
• support in treatment decisions (medical, interventional, or surgical) and follow-up monitoring.

Benefits for the patient

• safe and painless, with no radiation exposure;
• provides detailed information about the vascular system;
• helps in early diagnosis and prevention of vascular complications (stroke, thrombosis);
• enables targeted and effective, personalized treatment.
