Type A Dissection
A 91-year old man complained of sudden
onsets of chest pain and collapsed. He be-
came unconscious with a massive stroke. CXR
showed a widened medisatinum (left).
CT scan confirmed an extensive Stanford Type
A aortic dissection. The dissection involved
the left common carotid and subclavian ves-
sels (green arrow). The innominate artery
was occluded (orange yellow). The primary
tear was in the ascending aorta.
Type A Dissection has a very high mortality if
untreated due to target vessel compromise
(carotid and coronary), and cardiac tampon-
ade.
