TEVAR
Pronunciation: TEH-var
Also written as: TEVAR — thoracic endovascular aortic repair
Thoracic endovascular aortic repair; minimally invasive treatment of thoracic aortic pathology using stent grafts.
Full Definition
Thoracic endovascular aortic repair (TEVAR) is a minimally invasive procedure for treating thoracic aortic aneurysms, dissections, and other pathology using covered stent grafts deployed via percutaneous or surgical arterial access. TEVAR has largely replaced open thoracic aortic surgery for suitable anatomy, offering reduced morbidity and mortality. The procedure requires careful pre-operative planning, appropriate device selection, and long-term surveillance. This acronym appears in procedure schedules, operative reports, and follow-up imaging studies.
Usage
Usage note: Always capitalize as TEVAR. Distinguish from EVAR (endovascular anortic repair) which typically refers to abdominal procedures.
In Context
- "TEVAR was performed for a 6-cm descending thoracic aortic aneurysm." — Operative report
- "Post-TEVAR surveillance CT showed no endoleaks or device migration." — Follow-up imaging
