Visceral stent patency after fenestrated endovascular aneurysm repair using bare-metal stent extensions versus covered stents only

Fenestrated endovascular aneurysm repair (FEVAR) is an alternative to treat complex abdominal aortic aneurysms. Patency of visceral vessels remains high when covered stents are used. The use of distal uncovered stents to prevent kinking has been associated with loss of branch patency. The aim of this study was to evaluate branch-related outcomes of FEVAR using covered stents only vs the use of uncovered stents distal to covered stents.
