Most abdominal aortic aneurysms produce no symptoms (they are asymptomatic) and are discovered incidentally when an imaging test of the abdomen (CT scan or ultrasound) is performed. They can also be detected by physical examination when the health care professional feels the abdomen and listens for a bruit, the sound made by turbulent blood flow.
Pain is the most common symptom when the aneurysm expands or ruptures. It often begins in the central abdomen and radiates to the back or flank. Other symptoms can occur depending upon where the aneurysm is located in the aorta and whether nearby structures are affected.
Abdominal aortic aneurysms can remain asymptomatic or produce minimal symptoms for years. However, a rapidly expanding abdominal aneurysm can cause sudden onset of severe, steady, and worsening middle abdominal and back or flank pain. Rupture of an abdominal aortic aneurysm can be catastrophic, even lethal, and is associated with abdominal distension, a pulsating abdominal mass, and shock due to massive blood loss.
