Stanford classification | aortic dissections

Along with the DeBakey classification, the Stanford classification is used to separate aortic dissections into those that need surgical repair, and those that usually require only medical management. The Stanford classification divides dissections into:

• type A : Involves ascending aorta or aortic arch ~ 60% ( A affect ascending aorta and arch)
• type B : B begins beyond brachiocephalic vessels
  
  • involves descending aorta only ~ 40%
  • dissection commences distal to the left sub-clavian artery
