Long-term clinical outcomes of type 2 endoleak intervention and the crucial role of additional endoleak development after endovascular aneurysm repair: a single-center retrospective observational cohort study.

ABSTRACT:

Purpose

The primary objective of this study was to evaluate long-term outcomes in patients who underwent endovascular treatments for type II endoleaks (T2ELs) following endovascular aneurysm repair (EVAR).

Methods

This single-center, retrospective study included patients who developed early T2EL after EVAR for abdominal aortic aneurysm. Patients were divided into those who did and did not receive intervention for T2EL. Study outcomes included 10-year overall survival (OS), open conversion-free survival, and T2EL regression rates without open conversion.

Results

Of the 385 patients who underwent EVAR between January 2006 and December 2016, 65 (16.9%) had early T2EL. Of these, 22 (33.8%) underwent T2EL intervention and 43 (66.2%) were treated conservatively. Eight (12.3
