Spontaneous rupture of a gastroduodenal artery side branch immediately following endovascular treatment of gastroepiploic artery aneurysm or pseudoaneurysm

Key clinical massage: Pseudoaneurysms and aneurysms of the visceral arteries are rare entities. To the best of our knowledge, rupture of a proximal parental artery during endovascular treatment of a visceral aneurism/pseudoaneurysm has not been reported and should be kept in mind as a tragic possibility immediately following an apparently successful management of them.

Abstract: A 55-year-old woman with a history of coronary artery disease was referred to our hospital with abdominal pain as her primary complaint. Early works revealed anemia, a small amount of free peritoneal fluid, and a possible large aneurysm or pseudoaneurysm by the greater curvature of the stomach. She underwent emergency angiography that showed a large aneurism/pseudoaneurysm of the gastroepiploic artery. Successful embolization of the lesion was performed using the isolation technique. Perforation of a side branch of the gastroduodenal artery was observed on the immediate postembolization control angiography. Therefore, parent artery coiling was done immediately with good results. She was symptom-free and stable hemodynamically after the procedure, during the hospital course, and in the follow-ups.
