Type A aortic dissection: extensive and causing bilateral renal infarction and right external iliac artery occlusion


Two working classifications of the aortic dissection:

  • Stanford classification
    • Type A (60%): Involves ascending aorta, ± descending aorta
      • surgical treatment
    • Type B (40%): Excludes ascending aorta; involves descending aorta &/or aortic arch
      • medical management
  • DeBakey classification
    • Type I: involves ascending aorta, aortic arch, and descending aorta
    • Type II: involves ascending aorta
    • Type III: involves descending aorta distal to left subclavian artery
