Symptoms
By Mayo Clinic staffAortic aneurysms often grow slowly and usually without symptoms, making them difficult to detect. Some aneurysms will never rupture. Many start small and stay small, although many expand over time. Some aortic aneurysms enlarge slowly, increasing less than half an inch (1.2 centimeters) a year. Others expand at a faster rate, which increases the risk of rupture. How quickly an aortic aneurysm may grow is difficult to predict.
As an aortic aneurysm grows, some people may notice:
- Tenderness or pain in the abdomen or chest
- Back pain
Aneurysms can develop anywhere along the aorta, which runs from your heart through your abdomen. When they occur in the upper part of the aorta, they are called thoracic aortic aneurysms. More commonly, aneurysms form in the lower part of your aorta and are called abdominal aortic aneurysms. Rarely, an aneurysm can occur in between the upper and lower parts of your aorta. This type of aneurysm is called a thoracoabdominal aneurysm.
When to see a doctor
You should see your doctor if you have symptoms of a thoracic aortic aneurysm.
If you have a family history of aortic aneurysm, Marfan syndrome or other connective tissue disease, or bicuspid aortic valve, your doctor may recommend regular ultrasound exams to screen for aortic aneurysm.
