Overview
Several different classification systems have been used to describe aortic dissections. The systems commonly in use are either based on either the anatomy of the dissection (proximal, distal) or the duration of onset of symptoms (acute, chronic) prior to presentation.
Classification
- Several classification systems have been suggested for the description of aortic dissection.[1][2][3][4]
- The commonly used classifications for aortic dissection are either based on the timing of the symptoms or the anatomy of the dissection.
- DeBakey and Stanford systems are the commonly used classification systems for aortic dissection.
DeBakey Classification System
The DeBakey system is an anatomical description of the aortic dissection. It categorizes the dissection based on where the original intimal tear is located and the extent of the dissection (localized to either the ascending aorta or descending aorta, or involves both the ascending and descending aorta.[5]
- Type I - Originates in ascending aorta, propagates at least to the aortic arch and often beyond it distally.
- Type II – Originates in and is confined to the ascending aorta.
- Type III – Originates in descending aorta, rarely extends proximally.
- Type III A: Restricted till the descending thoracic aorta
- Type III B: Dissection extending below the diaphragm
Chronic dissection is almost twice as common in patients with type III (45%) when compared with type I (24%) and type II dissection (27%).

Stanford Classification System
Divided into 2 groups; A and B depending on whether the ascending aorta is involved.[6]
- A = Type I and II DeBakey
- B = Type III Debakey
Classification based on the Proximity
- Proximal: Ascending aortic involvement
- Distal: Descending aortic involvement distal to left subclavian artery
Classification by the Time of Onset
- Acute: Onset within 2 weeks of onset of pain
- Subacute: Onset within 2-6 weeks of onset of pain
- Chronic: Onset within 6 weeks of pain.
