What is an Aortic Arch Thoracic Aneurysm?
An aortic arch thoracic aneurysm is bulging and weakness in the wall of the aortic arch, where the aorta turns towards the back and has a candy-cane curl. The aorta is the largest blood vessel in the body, located in the chest, which delivers blood from the heart to the rest of the body. An aortic arch thoracic aneurysm can burst, which can cause life-threatening uncontrolled bleeding.
