Aortic Aneurysm (cont.)
IN THIS ARTICLE
Thoracic aortic aneurysms are much less common than abdominal aortic aneurysms. They are often caused by an abnormal breakdown of the elastic fibers in the aortic wall.
A pseudoaneurysm happens when a bulge occurs in the wall of the aorta. But the bulge doesn't affect all three layers of tissue in the wall of the aorta. This type of aneurysm might be caused by an injury.
