title: True pancreaticoduodenal aneurysms with celiac stenosis or occlusion.
abstract: BACKGROUND
  Pancreaticoduodenal artery (PDA) aneurysms are rare, representing only 2% of all visceral artery aneurysms. True PDA aneurysms associated with celiac stenosis or occlusion make up an even smaller subset of this group. No relationship between aneurysm size and the likelihood of rupture of PDA aneurysms is apparent. PDA aneurysm rupture is associated with a mortality rate upwards of 50%; therefore, accepted practice is treatment upon diagnosis. There is debate in the literature on whether the treatment of coexisting celiac axis stenosis is necessary for the prevention of recurrence.
  
  
  METHODS
  Literature relating to PDA aneurysms associated with celiac stenosis or occlusion was identified by performing a PubMed keyword search. References from identified articles were also assessed for relevance. The current literature was then reviewed and summarized.
  
  
  CONCLUSIONS
  Characteristics of this patient population are identified. Based on current evidence, our best practice recommendation for the treatment of coexisting celiac axis stenosis is provided.
