Aortic Dissection is a very specific description of the aorta breaking down in a specific way. Sometimes in media terms are used that are not entirely correct, but this is not so strange, since AD is a very rare condition.
Aortic Aneurysm, aortic rupture, ruptured aorta are wordings used in the english language sometimes when talking about aortic dissection. But they are not exactly the same.
