Coil Embolization of an Inferior Pancreaticoduodenal Artery Aneurysm Associated with Celiac Artery Occlusion

Pancreaticoduodenal arcade aneurysms are rare. Untreated, these lesions enlarge progressively and have the potential for spontaneous rupture. Aneurysmal degeneration of pancreaticoduodenal arcade vessels is known to be associated with celiac artery occlusion, vasculitis, and certain connective tissue disorders. Given their precarious location, surgical expiration is a challenging endeavor. Innovations in endovascular techniques offer a possible alternative. We report a case of a 55-year-old gentleman with a 2.2 × 2.1 - cm aneurysm of one of the inferior pancreaticoduodenal arteries and a concomitant finding of occlusion of the celiac artery trunk. Percutaneous coil embolization of the aneurysm was employed as the treatment in this case with the successful exclusion of the aneurysm sac, while maintaining continuity of the native circulation. This case report demonstrates that, due to the success rate of aneurysm exclusion and the relatively low morbidity and mortality rates seen with endovascular repair as compared to surgical intervention, endovascular treatment has become the treatment of choice for pancreaticoduodenal artery aneurysms.
