Endovascular Coil Embolization of an Enlarging Gastroduodenal Artery Aneurysm.

Gastroduodenal artery aneurysms are a rare type of visceral aneurysm that can lead to rupture and death. We present a 75-year-old male with history of hypertension, diabetes, and hyperlipidemia with an incidental finding of a 3.2 × 3.7 cm gastroduodenal aneurysm found on abdominal computed tomography angiography (CTA). After refusing surgical intervention, he was seen two years later and presented with an enlarged gastroduodenal aneurysm, now 5.0 × 5.1 cm, visible on a repeat abdominal CTA. Upon his continued refusal for an open surgery, we elected for endovascular repair of this GDA aneurysm via coil embolization.
