Long-term Clinical Outcomes and Predictors of Type-III Endoleak in a Large Cohort of Patients Treated With Anatomically Fixed Stent Grafts Over 20 Years.

Objective: To assess the incidence, outcomes, and predictors of type III endoleaks (TIIIELs) in patients treated with different generations of Endologix unibody devices for abdominal aortic aneurysm (AAA).

Methods: Patients treated with unibody endografts between 1999 and 2020 in a single unit were prospectively enrolled, retrospectively analyzed, and stratified according to device generation. The primary outcome was the incidence of TIIIEL in patients treated with unibody devices.
