Inferior pancreaticoduodenal artery aneurysms in association with celiac stenosis/occlusion.

Inferior pancreaticoduodenal artery aneurysms in association with celiac stenosis or occlusion are well described in the literature. These aneurysms are true aneurysms and develop as a result of increased flow through the pancreaticoduodenal arcades in the presence of hemodynamically significant stenosis of the celiac axis or common hepatic artery. Aneurysms may be multiple and rarely associated with aneurysms in other collateral pathways-such as the dorsal pancreatic artery or the arc of Buhler. These aneurysms may be incidentally detected or patients may present with abdominal pain or shock secondary to rupture of the aneurysms. Treatment options include surgical resection and transcatheter embolization; current literature favors the latter option. Treatment of celiac axis stenosis may be recommended in addition to treating the aneurysms; however, no formal guidelines exist on this recommendation.
