What is an AAA Ultrasound?
An Abdominal Aortic Aneurysm Ultrasound (AAA) is a non-invasive test used to measure the width of your Aorta – the main artery in your body. Sometimes, plaque build-up causes the walls of the abdominal aorta to become weak and bulge out like a balloon. An AAA Ultrasound will determine if this has happened and if so, measure the size of the bulge.
How does it work?
Ultrasound gel will be placed on your abdomen. The Sonographer will use a small hand-held device that emits high-frequency sound waves to produce images of your aorta. From those images, an assessment of your abdominal aorta is made and then reviewed by a Vascular Surgeon.
How do I prepare for the test?
You will need to fast for 4hrs NBM (nil by mouth) prior to having an AAA Ultrasound. 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?
An AAA Ultrasound takes approximately 30 minutes.
