Endovascular coil embolization for a giant anomalous splenic artery aneurysm

Abstract

Splenic arteries arising from superior mesenteric arteries, also known as splenomesenteric trunks, are uncommon entities. Aneurysms in relation to these variant splenic arteries are even rarer. Open surgery, laparoscopic technique, or endovascular management could be chosen. We report a patient with an anomalous splenic arteries aneurysm that was excluded with coil embolization in a minimally invasive endovascular way. A follow-up contrast-enhanced computed tomography angiogram performed 1 year after the procedure showed total exclusion of the aneurysm sac, patency of the superior mesenteric artery, and the patient was in good condition.
