A Modern, Minimally Invasive Way to Repair a Dangerous Aortic Bulge
An aortic aneurysm is a weak, bulging area in the body’s main artery (the aorta). If it grows or bursts, it can be life-threatening.
TEVAR (Thoracic Endovascular Aortic Repair) and EVAR (Endovascular Aneurysm Repair) are minimally invasive, image-guided procedures that repair the aneurysm from inside the artery—often without open surgery.
In both procedures, doctors:
This treatment:
An aortic aneurysm is a balloon-like bulge in the wall of the aorta, the main artery that carries blood from the heart to the body.
It can occur in:
Why it is dangerous:
Common risk factors:
The procedure is performed by a vascular or endovascular specialist in a cath lab or operating room under X-ray guidance.
Step-by-step:
TEVAR/EVAR are generally safer than open surgery, especially in high-risk patients. Possible risks with approximate incidence include:
Your treatment choices depend on:
Your vascular specialist will help you choose the safest option.
Alternative 1: No Active Treatment (Observation Only)
Alternative 2: Open Surgical Repair of the Aorta
Choosing the Right Aneurysm Treatment
Many patients today benefit from minimally invasive endovascular aneurysm repair (EVAR), which treats the aneurysm with less pain, lower risk, and faster recovery compared to open surgery. A personalized evaluation helps determine the best and safest treatment plan.
📌 TEVAR/EVAR is often preferred when the aneurysm is large, growing, or at risk of rupture and anatomy is suitable.
After TEVAR/EVAR:
EVAR (Endovascular Aneurysm Repair) treats aneurysms in the abdominal aorta, and TEVAR (Thoracic Endovascular Aortic Repair) treats aneurysms in the chest (thoracic) aorta. Both use a stent-graft placed inside the artery to seal off the aneurysm.
An aortic aneurysm is a weak, bulging area in the wall of the aorta (the body’s main artery). If it grows or bursts, it can cause life-threatening internal bleeding.
These procedures are considered for patients who have:
It is a minimally invasive, catheter-based procedure, not traditional open surgery.
It is done under general or spinal anesthesia, so you won’t feel pain during the procedure. Recovery pain is usually much less than open surgery.
The procedure usually takes 2 to 4 hours, depending on the complexity of the aneurysm.
Most patients stay in the hospital for 2 to 5 days, which is usually shorter than with open surgery.
Yes. In suitable patients and experienced centers, TEVAR/EVAR is safe and widely used around the world.
Possible risks include bleeding, infection, kidney strain from contrast dye, or leak around the stent (endoleak). Serious complications are uncommon.
An endoleak means some blood is still flowing around the stent-graft into the aneurysm sac. Many endoleaks are minor and monitored, but some need treatment.
Yes. You will need regular CT scans or ultrasound scans to make sure the stent-graft is working properly and the aneurysm is safely sealed.
Stent-grafts are designed to be long-lasting, but lifelong follow-up is important to ensure they continue to work well.
Many patients return to light activities in a few days and normal routine in 1–2 weeks, depending on recovery and doctor’s advice.
For many patients, yes. It is less invasive, has faster recovery, less pain, and shorter hospital stay. Some patients may still need open surgery depending on anatomy.
Yes. These procedures are available in advanced cardiac and vascular centers across India.

Safer option for many high-risk patients
Proven, life-saving technology
An aortic aneurysm can be silent but deadly if it ruptures. The good news is that modern, minimally invasive repair is available.
