Stent-assisted coil embolization of a complex wide-neck splenic artery aneurysm.

We describe the endovascular treatment of a wide-neck splenic artery aneurysm (SAA) using a stent-assisted coil embolization technique. A 55-year-old woman who was admitted for intermittent epigastric pain was diagnosed with a wide-neck aneurysm of the intermediate splenic artery. The SAA had a maximum diameter of 2.2 cm and originated from a tortuous vessel. After percutaneous access through the left brachial artery, a self-expandable stent was initially deployed across the origin of the aneurysm using a 4-French platform. The aneurysm sac was subsequently filled with coils through a microcatheter. The procedure was successful with no postoperative clinical complications. Patency of splenic artery and complete exclusion of the aneurysm were confirmed by follow-up computed tomographic angiography 1 year after treatment. In challenging anatomic situations, stent-assisted coil embolization may represent a first-choice endovascular treatment option for the exclusion of SAAs.
