Aortic aneurysm

An aortic aneurysm is a general term for any swelling (dilatation or aneurysm) of the aorta, usually representing an underlying weakness in the wall of the aorta at that location. While the stretched vessel may occasionally cause discomfort, it is the risk of rupture causing severe pain, massive internal hemorrhage and, without prompt treatment, resulting in a quick death. In addition the aneurysm may split (Aortic dissection) which may block vessels that branch off from the aorta or release blood clots (emboli) causing blockage to blood-flow elsewhere.
