Aneurysms of aorta are more common in the abdominal part of aorta. The exact cause of abdominal aortic aneurysms is unknown, but various factors may play a role, which include:
- Smoking. Both, cigarette smoking as well as chewing other forms of tobacco appears to increase the risk of aortic aneurysms. Additionally, smoking causes direct damage to the arteries, contributing to the buildup of fatty plaques in arteries (atherosclerosis) and high blood pressure. Aneurysms tend to increases in size faster in smokers, further increasing the risk of rupture.
- Hardened arteries (atherosclerosis). Risk of aneurysm increases when fat and other substances build up on the lining of a blood vessel (a process called atherosclerosis).
- Aortic wall infection (vasculitis). Abdominal aortic aneurysm, in rare instances, may be caused by an infection or inflammation that weakens a section of the aortic wall.
