The aim of this randomized study is to compare the safety and performance of EndoVascular Aneurysm Repair with ESAR using Endurant + Heli-FX™ EndoAnchor™ system and FEVAR using customizable grafts from Cook (Zenith Fenestrated Graft) and Terumo (Fenestrated Anaconda Graft) for the treatment of aortic aneurysms with short aortic neck (4 to 15mm).

Condition Aortic Aneurysm, Abdominal
Treatment ESAR treatment: Endograft + Heli-FX Endoanchor, FEVAR treatment : Fenestrated endograft
