An aortic aneurysm is an abnormal widening of the body's main artery, most often in the abdomen. Many cause no symptoms and are found by chance on a scan; their importance lies in the risk of rupture as they grow.

- A noticeable pulsation in the abdomen
- Abdominal or lower back pain
- Sudden severe pain if it ruptures, an emergency
Causes & risk factors
- Smoking
- High blood pressure
- Age
- Family history of aneurysm
Diagnosis
It is detected by abdominal ultrasound, and its size and shape are defined by contrast CT, which decides between surveillance and intervention.
Treatment options
Regular surveillance
For small aneurysms, with blood-pressure control and stopping smoking.
Endovascular stent-graft (EVAR)
Placed through the groin arteries without opening the abdomen in suitable cases.
Open surgery
For some cases depending on the aneurysm's anatomy and the patient's condition.
After treatment
After endovascular repair the hospital stay is usually short, with periodic imaging to confirm the graft remains stable.
