Aortic aneurysm or dissection

Description

Aortic aneurysm is a term for any swelling (dilation or aneurysm) of the aorta to greater than 1.5 times normal, usually representing an underlying weakness in the wall of the aorta at that location. Aortic dissection occurs when a tear in the inner wall of the aorta causes blood to flow between the layers of the wall of the aorta, forcing the layers apart.
