Management of aortic aneurysms depends on where it is, how big, whether it's growing, ...Read more

What is the pathophysiology of abdominal aortic aneurysm?

What is the pathophysiology of abdominal aortic aneurysm?

Inflammatory process: The exact mechanism for AAA formation is not known. There are several etiologies/theories. The most widely accepted is that aaas form due to an inflammatory process in the wall of the aorta associated with atherosclerosis. Inflammatory cells are thought to degrade structural proteins (such as elastin) in the wall of the aorta, weakening it and allowing for aneurysm formation. ...Read more

What does a tortuous abdominal aortic aneurysm mean?

With twists/bends: The term "tortuous" simply means: full of twists, turns and bends. In medicine we use this to describe the pathway of veins or arteries.

As they grow longer, they start bending and twisting to accommodate and "fit" into the same body. ...Read more
