Endovascular Repair of a Complex Splenic Artery Aneurysm Using a Multilayer Stent

To the Editor,
Based on autopsy studies, the prevalence of visceral artery aneurysms has been estimated to be up to 10 % , with up to 25 % complicated by rupture and a mortality rate of up to 70 % . Splenic artery aneurysms (SAA) account for ~60 % of visceral artery aneurysms . Asymptomatic SAA larger than 2 cm should be treated either by operation or endovascular techniques [3, 4]. In recent years, exclusion of aneurysms by implanting multilayer stents is considered an attractive, minimally invasive treatment option [5, 6, 7, 8, 9]. Due to the multilayer design of this vascular prosthesis, the tubular, self-expanding multilayer stent (Cardiatis, Isnes, Belgium) is supposed to decrease velocity and vorticity of intra-aneurysmal blood flow. Thereby, thrombus formation within the aneurysm sac shall be deemed over time. The affected main artery and moreover branching vessels deriving from the aneurysm or the proximal and distal landing zones are expected to remain patent due to...
