This is a retrospective cohort study of consecutive patients submitted to elective EVAR, between February/2009 and May/2019 in a single institution. Symptomatic or ruptured AAA, mycotic aneurysms, isolated iliac aneurysms and complex abdominal aortic repairs were excluded. The primary outcomes were freedom from secondary intervention and compliance with follow-up, defined as surveillance imaging performed within a periodicity no longer than 18 months.

Number of participant with secondary intervention (SI) after EVAR
SI included: access-related SI included suture of access bleeds, distal thrombo-embolectomy, patch angioplasty, or thromboendarterectomy of the common femoral artery; limb graft occlusion was defined as a thrombotic obstruction of blood flow in one or both endograft limbs, being a potential threat to the limb; lower limb ischemia was considered when there was a decrease in arterial perfusion of the limb, that was not related with limb graft occlusion; endoleak; stent migration was reported if no simultaneous type 1 endoleak was observed.
Time frame: 5 years follow up
Number of participant with compliance with follow-up after EVAR
