What is it?

The supra-aortic trunks are the arteries that leave the heart and run up the neck to supply the brain: the carotid and vertebral arteries. A neck (carotid) Doppler ultrasound examines them through the skin of the neck. Depending on the referral, it is performed by a cardiologist, an angiologist (a doctor specialising in blood vessels) or a radiologist. The ultrasound shows the artery walls and any cholesterol plaques (atheroma); the Doppler measures the speed of blood flow, which makes it possible to assess the degree of narrowing (carotid stenosis). It is requested after a stroke or a transient ischaemic attack (TIA), when the doctor hears a bruit in the neck, or as part of a cardiovascular check-up. No injection is needed.

When is it prescribed?

After a stroke or transient ischaemic attack (TIA)

It looks for a plaque or narrowing of a carotid artery that might have caused the event.

Bruit heard in the neck

A bruit heard with the stethoscope can mean narrowing: the test confirms and measures it.

Cardiovascular check-up

In people at risk (smoking, diabetes, high cholesterol, high blood pressure), it assesses the neck arteries.

Monitoring of carotid stenosis

It follows a known narrowing over time or checks an artery after surgery.

Preparation

1Leave your neck free: avoid polo necks, scarves and necklaces

2No fasting or special preparation is needed, unless you are told otherwise when booking

3Bring a list of your medicines, especially blood thinners; do not stop them without medical advice

4Bring your referral, previous tests (Doppler ultrasound, CT scan, MRI, angiography) and any relevant reports

How the exam is performed

You lie on your back, with your head turned slightly away from the side being examined

A gel is applied to the skin to help the ultrasound pass through; it may feel a little cold

The probe glides along the neck, first on one side and then the other

You may hear a rhythmic whooshing sound: this is the sound of blood flowing, picked up by the Doppler

You may be asked not to talk or swallow during some measurements

The gel is wiped off at the end; you can return to your usual activities straight away

Duration

About 15 to 30 minutes

Results

The doctor performing the test (cardiologist, angiologist or radiologist, depending on the referral) analyses the images and measurements during the examination, then writes a report. The report is given to you and sent to your doctor, who will explain the results and the next steps. You will be told when to expect it on the day of the examination.

Risks and side effects

No X-rays: Doppler ultrasound uses only ultrasound waves

No injection or contrast agent

Painless; the pressure of the probe may be a little uncomfortable over a tender area

Can be done during pregnancy, as ultrasound is not radiation

These risks remain rare. Your physician will explain them in detail before the exam.
