Yes, you can live with an aortic aneurysm, and there are many ways to prevent dissection (splitting of the blood vessel wall that causes blood to leak) or worse, a rupture (a burst aneurysm). Some aortic aneurysms are hereditary or congenital, such as bicuspid aortic valve, infection or inflammatory conditions. Others relate to personal habits.The aorta is the largest elastic artery in the human body and is classically divided into two anatomical segments, the thoracic and the abdominal aorta, separated by the diaphragm.
