Abstract:
Inferior pancreaticoduodenal artery aneurysms (IPDAAs) are rare visceral aneurysms that may rupture irrespective of size. Here, we report an IPDAA that progressively enlarged after celiac artery (CA) embolization during aortic stent-graft repair. An 84-year-old female developed a wide-necked saccular IPDAA that expanded from 2.5 to 15 mm over 10 years after CA embolization. Stent-assisted coil embolization using the double microcatheter technique was performed to preserve superior mesenteric artery-to-CA collateral flow, achieving a packing density of 31%-45%. This case highlights the need for surveillance after CA embolization and supports the feasibility and effectiveness of this technique in select cases.
