TEVAR
Pronunciation: TEE-var
Also written as: TEVAR — Thoracic Endovascular Aortic Repair
Thoracic endovascular aortic repair, a minimally invasive procedure using stent grafts to treat thoracic aortic pathology.
Full Definition
Thoracic endovascular aortic repair (TEVAR) is a minimally invasive surgical technique that uses covered stent grafts delivered via femoral artery access to treat thoracic aortic aneurysms, dissections, and other pathologies. This procedure offers reduced morbidity and mortality compared to open surgical repair, particularly in high-risk patients. TEVAR requires precise anatomical measurements and careful patient selection based on aortic morphology and landing zones. The technique has revolutionized the treatment of thoracic aortic disease since its introduction in the 1990s.
