Definition
A tear in the layers of the aorta especially in the intima leading to bleeding and separation of the layers of the aorta from within which creates a false lumen.
Classification
DeBakey and Daily (Stanford) systems are the commonly used systems used to classify aortic dissection.[1][2][3][4]
- Stanford system classifies dissection into the following two types.
- Ascending aortic dissection or type A
- All other dissections or type B
- DeBakey system classifies dissection according to location of the tear.
- Type 1- Starts at ascending aorta and extension upto the aortic arch.
- Type 2- Starts and is limited till the ascending aorta
- Type 3- Starts in the descending aorta and progresses proximally or distally.
- The third type of classification divides aortic dissection according to the proximity
- Proximal- Ascending aortic involvement
- Distal- Descending aortic involvement distal to left subclavian artery.
Causes
Life Threatening Causes
Aortic dissection is a life-threatening condition and must be treated as such irrespective of the causes. Life-threatening conditions may result in death or permanent disability within 24 hours if left untreated.
Common Causes
- Atherosclerosis
- Complication of cardiac procedures
- Chest trauma
- Connective tissue disorders
- Hypertension
- Vasculitis[5]
