Aortic Aneurysm Screening in Singapore
Who should consider a scan of the aorta, how it is done, and what happens if an aneurysm is found.
Short answer: an abdominal ultrasound measures the aorta to look for an abdominal aortic aneurysm (AAA). An aneurysm can be present without pain, so screening is worth discussing if you have a family history of aneurysms, or if you are a man over 55, particularly with a smoking history or high blood pressure. The scan is done at Mount Elizabeth Novena Specialist Centre.
Who should consider screening?
- People with a parent, brother or sister who had an aortic aneurysm or dissection.
- Men over 55, particularly with a smoking history or high blood pressure.
- People with other artery disease, where your doctor advises it.
The decision also considers age, general health and whether finding an aneurysm would change care. Feeling well does not reliably exclude an aneurysm, and waiting for symptoms is not a screening strategy.
How is screening done?
An abdominal ultrasound measures the width of the aorta. It is quick and uses no radiation. An abdominal ultrasound is not a complete screening test for every condition affecting the chest aorta, so other imaging may be advised in some situations. See vascular ultrasound and duplex scans.
What happens if an aneurysm is found?
Most aneurysms found on screening are watched with repeat scans. The interval between scans depends on the diagnosis and measurements. Blood pressure control and stopping smoking are part of the plan. If an aneurysm reaches a size or shape where repair is advised, the options are explained in EVAR, open aortic surgery and EVAR versus open repair. The aortic disease guide covers aneurysms and dissection in more detail.
When it is an emergency
Call 995 for sudden severe pain in the chest, back or abdomen. New abdominal or back pain needs a clinical assessment appropriate to its severity; it should not be booked as a routine screening appointment.
Common questions
Does screening hurt?
No. It is an ultrasound scan of the abdomen, similar to other abdominal ultrasound scans.
I have a family history. Should my relatives be checked?
The type of aortic disease and the family history help determine whether relatives need imaging or genetic assessment. Bring details of the family history to the consultation.
What if my scan is normal?
A normal scan is reassuring. Your doctor will advise whether any repeat scan is needed, based on your age and risk factors.
