TEVAR — Thoracic Endovascular Aortic Repair
Thoracic endovascular aortic repair (TEVAR) is a minimally invasive treatment for diseases of the thoracic aorta — including aneurysm and Stanford Type B dissection — using a stent graft delivered through the vessels. Suitability is determined by anatomical and clinical evaluation.
What is TEVAR?
TEVAR places a covered stent graft inside the thoracic aorta to exclude an aneurysm or to cover the entry tear of a dissection, supporting blood flow through the true lumen — in appropriate patients and according to manufacturer instructions for use.
When is TEVAR considered?
TEVAR may be considered for descending thoracic aortic aneurysms and for complicated Stanford Type B aortic dissection, where anatomy provides an adequate proximal and distal landing zone. The choice between TEVAR, open surgery and medical management rests with the treating physician.
TEVAR and EVAR
TEVAR addresses the thoracic (chest) aorta, while EVAR addresses the abdominal aorta. The two share the endovascular stent-graft principle but differ in device design, landing zones and procedural planning.
How Korvia supports TEVAR cases
Korvia supports physicians and hospitals with TEVAR-capable stent-graft platforms — including Percutek Tycheseal — together with case planning, device sizing, procedural readiness, on-site clinical support and reliable product availability in Türkiye.
Frequently asked questions
What is TEVAR?+
TEVAR treats thoracic aortic disease, such as aneurysm and dissection, with an endovascular stent graft. The indication is determined by clinical evaluation.
What is the difference between EVAR and TEVAR?+
EVAR targets the abdominal aorta, while TEVAR targets the thoracic aorta. Device selection depends on the anatomical region and clinical context.
How is a thoracic aortic aneurysm treated?+
In suitable cases, endovascular methods such as TEVAR or open surgery may be considered; selection depends on anatomical and clinical evaluation.
When are endovascular methods used in aortic dissection?+
Particularly in complicated Stanford Type B dissection, TEVAR may be considered in suitable anatomy and with physician evaluation.
