Large aneurysms can be seen on a chest or abdominal x-ray.
They are also detected by studies such as routine ultra sound abdomen, CT scan, MRI, or echocardiography. These studies also help to determine the exact location
and size of the aneurysm. When a small aneurysm is found, the study used to find it is repeated on a regular basis, usually every six to twelve months, to monitor
any change in size. This helps determine the ideal time for surgical intervention.
Surgery is usually advised if the aneurysm is
- Larger than 5.5cm
- Growing by more than 1cm per year
- Causing pain
