Lower Limb Arterial Ultrasound

What is a Lower Limb Arterial Ultrasound?

A Lower Limb Arterial Ultrasound is a non-invasive test used to determine if there is any narrowing in your leg arteries by examining the velocity of blood flow through them. 

How does it work?

Ultrasound gel will be placed on your lower limb(s). The Sonographer will use a small hand-held device that emits sound waves to produce images of your lower limb arteries whilst gently squeezing your calf. From those images, an assessment of your lower limb arteries is made and then reviewed by a Vascular Surgeon. 

How do I prepare for the test?

No special preparation is required for a Lower Limb Arterial Ultrasound. Eat, drink and take your medication as usual. You will need to remove clothing from your legs, leaving underwear on. 

N.B. If you are having a AAA Ultrasound in conjunction with the Lower Limb Arterial Ultrasound, then  you will need to fast for 4hrs NBM (nil by mouth) prior. Drink water as usual. DO NOT fast if you are a Diabetic. Take your medication as usual. Wear clothing that can be easily removed from the waist up.

How long does the test take?

A Lower Limb Arterial Ultrasound takes approximately 60-90 minutes.
