EVAR
Pronunciation: EE-var
Also written as: EVAR — Endovascular Aneurysm Repair
Endovascular aneurysm repair using stent-grafts to exclude aneurysms from circulation.
Full Definition
Endovascular aneurysm repair is a minimally invasive surgical technique that uses stent-grafts inserted through femoral arteries to treat aortic aneurysms. The stent-graft is deployed within the aneurysm to redirect blood flow through the device, effectively excluding the aneurysm sac from circulation and preventing rupture. This approach offers reduced operative mortality and morbidity compared to open surgical repair, particularly in high-risk patients.
Usage
Usage note: Distinguish from TEVAR (thoracic endovascular aneurysm repair) in documentation.
In Context
- "The patient underwent successful EVAR with a bifurcated stent-graft for infrarenal abdominal aortic aneurysm." — Operative report
- "Five-year follow-up after EVAR showed stable aneurysm sac size with no evidence of endoleak." — Radiology report
