EnChEVAR (Endurant II/IIs stent graft system + Radiant† balloon-expandable covered stent) analysis (n = 62)3
ENCHANT is a multicentre, prospective, single-arm, post-market study to assess the clinical outcomes, safety, and performance of the Endurant II/IIs system used with balloon-expandable covered stents for treatment of juxtarenal aortic aneurysms with a short infrarenal neck in a real-world setting.
One year sac status by Core Lab (n = 41)‡
The PROTAGORAS study1 evaluated the performance of the Endurant™ II/IIs stent graft for patients with pararenal pathologic processes that were treated by the chemistry/snorkel endovascular technique.
Standardised use of the Endurant™ II/IIs stent graft system and Radiant™ covered stent for ChEVAR demonstrated:
Radiant™ covered stent shows significantly better performance in ChEVAR compared to other grafts, with 94.6% patency at midterm compared to 84.1% patency with other covered stents.2

Dr. Fazzini explains the benefits of the combination of Endurant™ II/IIs system and Radiant™ stent: safer procedure, shorter recovery times, and lower of reintervention rate.
Prof. Reijnen and Prof. Donas share their clinical experience about EnChEVAR technique with Endurant™ II/IIs system and Radiant™ covered stent.
