Aortic dissection and aortic aneurysm are two different conditions. Aortic dissection is a medical emergency caused when a tear on the inside of the aorta causes blood to enter the wall of the aorta. An aortic aneurysm, on the other hand, is a bulge in the aorta caused by a weakening of the artery walls, which can rupture if left untreated. Both conditions are serious and require prompt medical attention. The best thing you can do is stay informed about your health so you can recognise any warning signs and get help as soon as possible if needed.
