Aortic aneurysm – Definition
An aortic aneurysm is a weak, bulging area in the wall of the aorta. The bulging develops from a weakness or defect in the aortic wall and tends to get bigger with time. The aorta is the body’s largest artery. It carries blood from the heart for delivery to the rest of the body. The aorta travels through the chest (thoracic aorta) and the abdomen (abdominal aorta). Abdominal aortic aneurysms are more common than thoracic aortic aneurysms.
