Inflammatory AAA

 Q: All of the following are associated with inflammatory abdominal aortic aneurysm (AAA) EXCEPT

A) chronic abdominal pain 

B) weight loss 

C) elevated ESR 

D) Increased incidence of rupture

Answer: D

If following triad is present with AAA, it highly suggests inflammatory AAA

  • chronic abdominal pain
  • weight loss
  • elevated ESR

There is an interesting paradox in inflammatory AAA. Although there are more chances to be symptomatic when compared to the same size non-inflammatory AAA, the chance of actual rupture is low.

Said that, all symptomatic AAA require repair irrespective of size.
