Two classification systems exist for aortic dissections, the Stanford classifications and DeBakey classifications, but the Stanford classification is the one which is used. Stanford type A aortic dissection originates from the ascending aorta and may extend all the way to the iliac bifurcation. Stanford type B aortic dissection originates from the beginning of the descending aorta and may also extend to the bifurcation. Stanford type A is the worst type. | Two classification systems exist for aortic dissections, the Stanford classifications and DeBakey classifications, but the Stanford classification is the one which is used.

Dissection usually causes sudden severe pain in the chest, back (interscapular), abdomen, or neck. Depending on the complications of the dissection, symptoms of ischaemia of other organs as well as bleeding may also be present: | |||
