AbstractAneurysms of the pancreaticoduodenal artery are rare. Degeneration of pancreaticoduodenal arcade vessels due to these aneurysms is associated with celiac artery stenosis or occlusion. Untreated lesions enlarge progressively and may rupture spontaneously. As the location of aneurysms of pancreaticoduodenal arcade vessels renders their surgical extirpation a challenge, we examined whether endovascular techniques offer a treatment alternative. We report on 3 patients with aneurysms of the pancreaticoduodenal arcade vessels and concomitant celiac artery stenosis/occlusion due to compression by the median arcuate ligament or chronic pancreatitis. All patients were treated by percutaneous coil embolization of the aneurysm. The aneurysmal sac was successfully excluded and the native circulation was preserved. Endovascular surgery can be used to treat these aneurysms safely and permits retention of the native circulation.
