Effects of preoperative visceral artery stenosis on target artery outcomes after fenestrated/branched endovascular aortic aneurysm repair

F-BEVAR is associated with overall primary patency rates higher than 90% for the celiac artery and SMA. Preoperative celiac artery stenosis is associated with lower primary patency and freedom from target vessel instability. Conversely, neither SMA branch primary patency nor freedom from target vessel instability were affected by preoperative SMA stenosis. Of importance, visceral artery stenosis is a marker of atherosclerosis burden associated with reduced mid- and long-term patient survival.
