Endovascular exclusion of aberrant splenic artery aneurysm with covered stent.

The splenic artery arising from the superior mesenteric artery is an uncommon anatomical variant. This aberrant origin may rarely be associated with an aneurysm. Previous cases have been managed with surgery and combined surgical/endovascular or endovascular techniques, with the latter involving occlusion of the aneurysm with coils. We report a case of aberrant splenic artery aneurysm that was excluded with a balloon-mounted covered stent, and discuss the technical issues encountered in using this approach. A follow-up computed tomography performed six months after the covered stent placement showed persistent exclusion with marked shrinkage of the aneurysm sac.
