A patient has been diagnosed with an abdominal aortic aneurysm (AAA). Which statement related to the diagnosis is most likely true?

Atherosclerosis of the abdominal aorta causes damage to the arterial intima.

Streptococcus bacteria weaken arterial walls causing an outpouching of the arterial blood vessel.

Arterial valves become floppy allowing backflow and arterial congestion in the abdomen.

Hypotension will cause blood to seep from the lumen into the arterial muscle and tissue.
