TEVAR (Thoracic Endovascular Aortic Repair) is an advanced, minimally invasive procedure used to treat serious conditions involving the thoracic aorta — including aortic aneurysm, aortic dissection, traumatic aortic rupture, penetrating ulcers, and pseudoaneurysms.
Instead of open-heart or open-chest surgery, TEVAR uses a stent graft delivered through a small puncture in the groin artery, making the procedure safer with faster recovery and excellent long-term outcomes.
TEVAR treats life-threatening aortic diseases without open surgery and restores safe blood flow through the aorta.
What Is the Aorta?
The aorta is the largest artery in the body, carrying oxygen-rich blood from the heart to all organs. Damage to this artery can be life-threatening and requires timely treatment.
When Is TEVAR Recommended?
According to ACC/AHA, ESC, and Society for Vascular Surgery Guidelines, TEVAR is indicated when:
✔ Aortic Aneurysm:
- Thoracic aneurysm ≥ 5.5–6 cm
- Rapid growth (≥ 0.5 cm in 6 months)
- Symptomatic aneurysm
✔ Type B Aortic Dissection:
- Complicated dissection with:
- Persistent pain
- Organ malperfusion
- Hypertension uncontrolled with medicines
- Aortic expansion
- Imminent or actual rupture
✔ Trauma or Ulcer
- Suitable anatomy and risk of rupture
How TEVAR Is Performed
- ✔ Local anesthesia or short general anesthesia
- ✔ Access via femoral artery (groin)
- ✔ A catheter delivers a stent graft to the diseased aorta
- ✔ The stent expands to seal the tear or reinforce the weakened area
- ✔ Normal blood flow is restored immediately
Benefits of TEVAR
Compared to open surgery, TEVAR offers:
- Minimally invasive approach
- Faster recovery and less pain
- Lower risk of mortality and complications
- Lower hospital stay and blood loss
- Reduced risk of paralysis from spinal cord ischemia (with technique optimization)
- Suitable for elderly or high-risk patients
Large trials (INSTEAD-XL, ADSORB, IRAD registry) show improved long-term survival and aortic remodeling with TEVAR in suitable dissection patients.
