Most aortic aneurysms don't cause any symptoms. They often are discovered during routine physical exams. Or they are found on X-rays for unrelated illnesses.
When symptoms develop, they can include:
Rarely, floating blood clots form near the aneurysm. These clots can break away. They can block blood vessels elsewhere in the body.
Sometimes an undiscovered abdominal aneurysm ruptures without warning. The patient collapses and dies from massive bleeding inside the abdomen.
