Duplex Doppler ultrasound of the carotid and vertebral arteries

Duplex Doppler ultrasound of the carotid and vertebral arteries

The examination allows for the assessment of blood flow in the cervical segments of the arteries supplying the brain and the detection of possible stenoses caused, for example, by atherosclerotic plaques. Early identification of atherosclerotic changes and the implementation of appropriate treatment reduce the risk of stroke.

This examination is similar to other ultrasonography examinations - the doctor applies the transducer to the area above the running artery, observes the blood flow on the monitor and measures the diameter of the artery as well as the speed and direction of the blood flow.

The doctor’s comments to the examination are available immediately afterwards.

Duplex Doppler ultrasonography of the cephalad arteries is recommended for patients with: neurological symptoms such as sudden visual disturbances, dizziness and headaches, tinnitus, balance and memory disorders, the history of long-term hypertension and smoking, as well as the family history of early stroke deaths, the history of transient ischaemic attacks, suspected atherosclerosis, diabetes, hypertension.

The examination is painless and non-invasive - no special preparation is required.

The duration of examination is approximately 15-20 minutes.

There are no contraindications to carrying out the examination.
