Surgical Management of Pancreaticoduodenal Artery Aneurysms in Association with Celiac Trunk Occlusion or Stenosis

Aneurysms of the visceral arteries, especially of the pancreaticoduodenal artery, are rare. They show a wide clinical spectrum, ranging from asymptomatic incidental findings to rupture-inducing catastrophic bleedings. Since growth progression and the risk of rupture cannot be foreseen and there is no relation between the size of the aneurysm and propensity to rupture, rupture unfortunately carries a high mortality, >50%. Thus, all aneurysms of the pancreaticoduodenal artery should be treated. The therapy of choice, either operative intervention or catheter embolization, is determined by many factors. Among these are localization, size, relation to other vessels and neighboring organs, the urgency of intervention, and the experience of the therapist. Surgical therapy should be favored in patients with pancreaticoduodenal artery aneurysm due to celiac trunk occlusion. We report here our experience in the surgical treatment of pancreaticoduodenal artery aneurysms in association with celiac trunk occlusion or stenosis over the last 5 years.
