What is Endovascular Aneurysm Repair (EVAR & TEVAR) for Minimally Invasive Treatment of Aortic Aneurysms?

Endovascular Aneurysm Repair (EVAR) and Thoracic Endovascular Aneurysm Repair (TEVAR) are minimally invasive procedures used to treat weakened, bulging areas of the aorta known as aortic aneurysms. Using advanced imaging guidance, a stent graft is delivered through blood vessels to reinforce the aorta from within, preventing rupture and restoring safe blood flow. These catheter-based treatments avoid large surgical incisions and significantly reduce recovery time compared to open surgery.

EVAR is typically used for abdominal aortic aneurysms, while TEVAR treats aneurysms in the chest (thoracic aorta). Both procedures offer effective, durable aneurysm repair with lower complication risk, making them ideal for patients who are elderly, high-risk, or seeking a less invasive alternative to open aortic surgery.

Conditions Treated

  • Abdominal aortic aneurysm (AAA)
  • Thoracic aortic aneurysm (TAA)
  • Enlarging or symptomatic aortic aneurysms
  • High-risk aneurysms at risk of rupture
  • Patients unfit for open aneurysm surgery

Benefits of EVAR & TEVAR vs Open Surgery

EVAR / TEVAR

  • Minimally invasive, no major incision
  • Short hospital stay
  • Faster recovery
  • Lower complication risk
  • Less blood loss

Open Aortic Surgery

  • Large abdominal or chest incision
  • Prolonged hospitalization
  • Longer recovery period
  • Higher surgical risks
  • Greater surgical trauma

How the Procedure Works

  • A small catheter is inserted through arteries in the groin.
  • Angiography maps the aneurysm and aortic anatomy.
  • A stent graft is guided to the aneurysm site.
  • The graft is deployed to reinforce the aorta.
  • Imaging confirms proper placement and blood flow.

What to Expect (Before, During & After)

Risks & Considerations

EVAR and TEVAR are well-established and generally safe when performed by experienced vascular and interventional specialists. Possible risks include bleeding, endoleak (persistent blood flow around the graft), infection, or need for future monitoring. Regular follow-up imaging is essential to ensure long-term success and patient safety.

Frequently asked question

EVAR treats abdominal aortic aneurysms, while TEVAR is used for aneurysms in the thoracic (chest) aorta. Both use stent grafts placed through blood vessels.

For many patients, yes. EVAR and TEVAR have lower complication rates, shorter hospital stays, and faster recovery compared to open surgery.

Stent grafts are designed for long-term durability. Lifelong follow-up imaging is important to monitor graft position and function.

Patients with suitable aneurysm anatomy who want a minimally invasive option or are high-risk for open surgery are often good candidates.
