Abstract

Background/Objectives: Device selection during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) remains an important issue for ensuring endograft durability. This study evaluated the early and follow-up outcomes of elective EVAR with the Endurant platform. Methods: A single-center retrospective analysis was conducted including consecutive elective EVAR procedures with the Endurant II/IIs (2008 to 2024) device. Primary outcomes were technical success, mortality and major complications at 30 days. Survival, endoleak I/III and freedom from reintervention were secondary outcomes. Cox proportional hazards models were employed for risk-adjusted follow-up outcomes. Results: In total, 361 patients were included (72.7 ± 7 years; 96% males; mean AAA diameter 62 ± 14 mm); 92% received a bifurcated device, and 89% conformed to the instructions for use. Technical success was 99.7%. Intra-operative adjunctive procedures included 4.4% proximal cuffs and 1.7% endoanchors. The thirty-day mortality rate was 0.6%, and the major complication rate was 4.1%. Survival was 81% (SE 4.8%), 72% (SE 6.4%) and 52% (SE 9.2%) at 4, 6 and 8 years, with aneurysm-related mortality at 1.7%. Freedom from endoleak Ia was 76% (SE 7.3%) at 6 years, freedom from endoleak Ib was 79% (SE 7.4%) at 7 years and freedom from endoleak III was 94% (SE 3.7%) at 5 years. Freedom from reintervention was 71% (SE 6.1%) and 55% (SE 7.9%) at 5 and 7 years, respectively. No device-related co-factor affected long-term outcomes. Conclusions: Endurant II/IIs endograft is a safe and effective EVAR solution with excellent early outcomes and low long-term aneurysm-related mortality. The need for reintervention in the long term affected less than 50% of cases. [ABSTRACT FROM AUTHOR]
