What is an Upper and Lower Limb Arteries Doppler Ultrasound?

An Upper and Lower Limb Arteries Doppler Ultrasound is a special type of ultrasound which is used to measure blood flow through the arteries of the upper and lower limbs, using high-frequency sound waves. The test is used to calculate the velocity of blood flow and to determine the degree of narrowing in the blood vessel, if any.

What happens during an Upper and Lower Limb Arteries Doppler Ultrasound?

A. Before your scan

What to bring

• Your request form
• Any relevant previous imaging
• Your Medicare card and any concession cards

Preparation – the day of your procedure

If your upper limb arteries are being imaged during this procedure, no special preparation is required. If your lower limbs are being scanned, you will need to fast for six hours prior to the procedure.

You will be asked to fill out a questionnaire regarding your health status, medication, and any known allergies. You may be asked to change into an examination gown and remove jewellery for your scan.

B. During your Upper and Lower Limb Arteries Doppler Ultrasound

Procedure

You will be made comfortable on the examination table. Gel will be applied to the area being imaged to help create a good contact between you and the ultrasound probe. The probe will be placed directly onto the gel and your skin for the duration of the examination. For an Upper and Lower Limb Arteries Doppler Ultrasound, the probe is placed on your limbs and gently moved back and forth to image the arteries.

If you are having this examination it is common to hear strange noises as the signals coming from the flowing blood are converted into sound. Sometimes the sonographer will have to gently squeeze the calf a few times when examining the veins in the legs. This should not be painful.

Most Doppler studies will be completed within 30-60 minutes. It is not unusual for the radiologist to come in and speak with you and view the images on the screen. At the end of the procedure the gel is simply wiped from your skin so that it does not mark your clothes.

Risks and side effects

Ultrasounds are a very low risk procedure and complications are rare however you should be informed of the possible risks and side effects.

Risks associated with this procedure include:

• If scanning is performed over an area of tenderness, you may feel pressure or minor pain from the transducer.

Any medical procedure can potentially be associated with unpredictable risks.
