Abdominal Aortic Aneurysm
Abdominal Aortic Aneurysm

Upper view is of the unopened aorta with a fusiform aneurysm just above the bifurcation (black arrow).
Lower view shows the aorta and common iliac arteries opened longitudunally.
The aneurysmal cavity is almost filled with an unorganized thrombus (white arrow) with a central channel of blood flow having the same diameter as the adjoining intact aorta.
Note that the arteriosclerotic intima lining the upper edge of the opened aneurysm (white asterisk) has been artefactually split from the media (blue arrow)
