EVAR
Pronunciation: EE-var
Also written as: EVAR — endovascular aneurysm repair
Minimally invasive repair of abdominal aortic aneurysm using stent-graft.
Full Definition
Endovascular aneurysm repair is a minimally invasive technique for treating abdominal aortic aneurysms using covered stent-grafts deployed via femoral artery access. EVAR requires specific anatomical criteria including adequate neck length, appropriate angulation, and suitable iliac access vessels. Documentation must include device specifications, deployment technique, and post-procedure imaging confirming exclusion of the aneurysm sac.
Usage
Usage note: Distinguish from TEVAR (thoracic) and FEVAR (fenestrated) procedures.
In Context
- "The patient is a candidate for EVAR based on favorable neck anatomy." — Pre-operative assessment
- "Post-EVAR CT angiography showed complete aneurysm exclusion without endoleak." — Follow-up imaging
