Acute aortic syndrome

  • Acute aortic syndromes are of 3 types:
    • Aortic dissection
    • Aortic intramural hematoma
    • Penetrating ulcer of the aorta.
  • They are an important differential diagnosis of acute coronary syndrome.
  • They are characterised by intense tearing pain, the location of which depends on the underlying lesion
  • In case of involvement of the ascending aorta, pain is felt in the anterior aspect of thorax and neck
