In most cases, aortic aneurysms do not cause any symptoms unless they rupture. They can form in the thoracic area (chest) or the abdominal area. Abdominal aortic aneurysms are frequently asymptomatic. They are often discovered when the doctor examines your abdomen or during imaging procedure - such as an ultrasound, computed tomography, magnetic resonance imaging, or X-ray — usually for an unrelated problem.Thoracic aortic aneurysms are also usually asymptomatic and found during an imaging procedure, but when large, may cause symptoms that include:
- Chest pain
- Back pain
- Shortness of breath
- Coughing
- Feeling full after only eating little
Large aortic aneurysms can rupture, causing sudden, severe stabbing pain (most often back pain), often followed by loss of consciousness. The loss of blood into the chest or abdomen results in shock. About 80% of those who have ruptured aneurysms die, half of them before reaching the hospital.
