The presentation and management of aneurysms of the pancreaticoduodenal arcade

GDAAs and PDAAs are uncommon lesions that are often associated with a celiac axis stenosis/occlusion leading to altered hemodynamics in the pancreaticoduodenal arcade. These aneurysms are prone to rupture regardless of size, and intervention is accordingly recommended for all aneurysms upon recognition. Despite the concordant celiac axis obstruction and concern for maintenance of hepatic circulation, endovascular repair of these aneurysms is generally successful and should be considered as the initial operative approach.
