Fenestrated Endovascular Aortic Repair

The registry population consists of patients presenting with complex aortic pathologies amenable to endovascular aortic repair that requires the incorporation of bridging stents to maintain visceral artery perfusion

This is a national multicenter study with 25 patients with a complex AAA undergoing endovascular repair with the Fenestrated TREO™ stent graft. ECG and respiratory-gated CT scans will be performed pre-operatively, at discharge, after 6 months, and after 12 months follow up. If stent movement is still present in after 12 months, then another scan will be taken at 24 months. To include respiratory gated with the ECG-gated, patients will undergo ECG-gated CT scan during an inspiration breath-hold as well as an expiration breath-hold. This double gated CT scans will allow us to analyse the movement of the stent graft caused by the cardiac cycle and respiratory cycle. The duration of this study is 2.5 years.

This randomized controlled unblinded trial aimes to compare BeFlared FEVAR Stent Graft System (BeFlared) with GORE® VIABAHN® VBX Balloon Expandable Endoprothesis (VBX) in patients undergoing endovascular aneurysm repair with fenestrated device (FEVAR). Primary objectives: * compare cumulative device time between patients undergoing FEVAR with BeFlared and VBX brindging device; * compare target vessel (TV) instability at early, short-term and midterm follow-up in patients undergoing FEVAR with BeFlared and VBX brindging device. Secondary objectives: \- compare intraoperative TV technical success in patients undergoing FEVAR with BeFlared and VBX bridging device.
