Inclusion criteria

Inclusion criteria: Patients who underwent endovascular repair for an abdominal aortic aneurysm between 2016 and 2019, using the National Clinical Database in Japan.

Exclusion criteria

Exclusion criteria: Patients with an aneurysm diameter < 25 mm were excluded from the study.

Design outcomes

Primary

Measure	Time frame
The primary outcome was the aneurysm diameter at which saccular AAAs were operated on by EVAR in the non-ruptured and ruptured cases.	—
