Stanford Classification (Aortic Dissection)

Stanford classification of aortic dissection asks one question, whether the ascending aorta is involved.

Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.

Example

Aortic arch
Yes
Descending thoracic aorta
Yes
Refractory pain or refractory hypertension
Yes

Result: Stanford type B, high-risk uncomplicated, with the arch involved.

The tool opens with these values already filled in. Replace them with your own.

What you enter

  • Ascending aorta (root to the innominate artery)
  • Aortic arch (innominate to the left subclavian artery)
  • Descending thoracic aorta (above the diaphragm)
  • Abdominal aorta (below the diaphragm)
  • Rupture, or periaortic hematoma
  • Malperfusion (visceral, renal, limb, or spinal cord)
  • Refractory pain or refractory hypertension
  • Early aortic expansion, or an aortic diameter over 40 mm
  • Bloody pleural effusion
