Classification. Type 2 originates and is limited to the ascending aorta (both would be considered Stanford Type A). There is also the DeBakey Classification, which subdivides aortic dissections as class I, II, IIIa, and IIIb as pictured below. Type A involves the ascending aorta and may progress to involve the aortic arch and thoracoabdominal aorta. Classification. DeBakey developed aortic dissection himself at age 97 in 2005, and underwent surgery in 2006. Normally, the aorta ascends in the superior mediastinum to the level of the sternal notch before arching posteriorly and descending in the left hemithorax. The high hydraulic stress regions are: The ascending wall of the aorta present to the right that is 5cm from the aortic valve; Away from the origin of the subclavian artery. Stanford classification. The origin of a dissection occurs due to an increase in the hydraulic stress. Function and physiology. Another classification system (DeBakey Classification) defines dissection by three types.

As with classical aortic dissection, penetrating atherosclerotic ulcers are classified according to the Stanford scheme.
