Endovascular Aortic Aneurysm Repair (EVAR) or Thoracic Endovascular Aortic Aneurysm Repair (TEVAR)

Endovascular aortic aneurysm repair (EVAR) is a surgery used to treat an abdominal aortic aneurysm (AAA). For a patient with a thoracic aortic aneurysm (aneurysm in the chest area), the procedure is termed thoracic endovascular aortic aneurysm repair (TEVAR).


Endovascular is a term that refers to “inside the blood vessels.” An aneurysm is the bulging or ballooning of a weakened area of a blood vessel.

  • The wall of the aorta (the largest blood vessel in the body) can become weak due to age
  • High blood pressure
  • Disease
  • Trauma.

This may cause the aortic wall to bulge, leading to an aortic aneurysm. As the bulge grows, the wall of the aorta becomes weaker. This may cause the aorta to rupture and lead to massive internal bleeding.
A ruptured aneurysm requires immediate medical attention. In most cases, patients have no symptoms. However, for those patients with symptoms, the most common are pain in the abdomen, back, or chest.

  1. It is a fabric tube supported by metal wire mesh that reinforces the weak spot in the aorta.
  2. It expands and allows blood to pass through without putting pressure on the aneurysm.
  3. The stent graft makes a new path for the blood to flow through and remains inside the aorta permanently.
  1. It is generally less painful.
  2. It has a lower risk of complications than traditional surgery (open surgical repair) because the incisions are smaller.
  3. Endovascular repair procedures also allow you to leave the hospital sooner and recover more quickly.
  • The possible complications of endovascular repair include:
  • Leaking of blood around the graft, known as endoleak
  • Stent fracturing
  • Blockage of the blood flow through the graft
  • Infection
  • Delayed aneurysm rupture
  • Renal failure (2%)
  • Deep vein thrombosis (DVT)
  • Blocked blood flow to the abdomen or lower body
  • Death
Open surgical repair involves making a large incision to remove the area where the aneurysm has damaged the aorta. The area is surgically separated from the aorta and replaced with a synthetic tube that is sewn into place. The surgery takes more time and results in a much longer hospital stay than endovascular aortic aneurysm repair (EVAR) or thoracic endovascular aortic aneurysm repair (TEVAR).
