An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst.
Aortic Aneurysm: What You Need to Know Aneurysms may be characterized by a severe, pulsing pain in the chest (thoracic aneurysm) or lower back (abdominal aneurysm). Many aneurysms are caused by atherosclerosis, a buildup of fatty plaque in the artery. People with certain connective tissue disorders may also be at risk. Treatment is based on an aneurysmâs size and rate of growth. Surgery is often needed to repair the aneurysm and avert a potential rupture.
