Type A involves the ascending aorta and is treated surgically by removing as much of the dissected aorta as possible and blocking the entry of blood into the aortic wall. Aortic dissection is defined as disruption of the medial layer of the wall of the aorta provoked by intramural bleeding, resulting in separation of the aortic wall layers and subsequent formation of a true lumen and a false lumen with or without communication. Treatment for Type A aortic dissection will include- Surgery for Type A Aortic Dissection Surgeons in this case remove most of the dissected aorta as possible and block the entrance of blood within the aortic wall.
