Can a traumatic fracture of the distal sternum cause an aneurysm ascending aortic artery?

A traumatic fracture of the distal sternum can rarely cause an aneurysm of the ascending aortic artery. The sternum is the flat bone that forms the front of the chest, and the ascending aortic artery is the large blood vessel that carries oxygenated blood from the heart to the rest of the body. If a traumatic fracture of the sternum occurs, it can damage the ascending aortic artery and cause an aneurysm to form. This is a serious condition that can lead to life-threatening complications, such as rupture of the aneurysm and bleeding. If you have experienced a traumatic fracture of the sternum, it is important to seek medical attention immediately to assess for any damage to the ascending aortic artery.
