Screening for Abdominal Aortic Aneurysm

Abdominal aortic aneurysm (AAA) is a condition in which the lining of the blood vessel called the aorta is enlarged within the abdomen. Because abdominal aortic aneurysms are likely to tear if they reach 5 centimeters in diameter, monitoring is important for preventing a rupture. A ruptured AAA can cause blood loss, shock, and death.
Life Line Screening uses ultrasound technology to measure the size of your abdominal aorta. The process is painless. You lie on your back on an exam table while gel is applied to your abdomen. The trained staff member then takes images and measurements of your aorta by moving an instrument called a transducer across your abdomen.
What you can learn
The abdominal aorta should measure less than 3 centimetres. If it measures more than 3 centimetres, an aneurysm is suspected. There are 2 types of aneurysms and our ultrasound equipment can screen for both. Abnormal screening results do not necessarily indicate the presence of an aneurysm, but they do warrant a visit to your GP for further evaluation.
Who should have AAA screenings?
Anyone who has risk factors for abdominal aortic aneurysms should have this screening.
How often should you get screened?
This is a personal decision based on your risk factors and previous screening results. Many of our customers have an annual screening as part of their regular healthcare regime.
How to prepare
Wear a comfortable 2-piece outfit consisting of loose clothing.
- Fast for 4 hours prior to your screening.
- Make sure the meal you eat 4 hours prior to your screening is a light one (less than 1/2 of what you normally eat of non-gassy food).
- If you are thirsty during your fasting period, you may have 1/2 a cup of coffee or tea and a moderate amount of water.
- If you take medication, take it as prescribed.
- If you are diabetic and are not comfortable fasting for 4 hours, please limit yourself to a "diabetic meal" (piece of toast, 1 cup of any kind of juice and 1/2 a cup of coffee or tea). If you are in doubt, please follow your diabetic care plan.
