About this trial
Prospective, randomized, multi-center study designed to evaluate the outcomes of commercially available contemporary EVAR in a real-world population. Patients will be randomized into two device cohorts and compared across the primary endpoints.
Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).
