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
Pain in the back or the abdomen is seen in involvement of the descending aorta
Acute aortic syndromes are seen in association with hypertension and collagen vascular disorders like Marfan syndrome
