What is thoracic endovascular aortic repair (TEVAR)?

Aortic damage in the chest can be repaired with a minimally invasive procedure termed thoracic endovascular aortic repair (TEVAR).

The aorta is your body's major artery. Its many branches supply blood to your tissues and organs. An aortic dissection, a tear in the lining of the artery, or an aneurysm, an abnormal enlargement in a weak place in the arterial wall, can occur. Medical practitioners commonly treat descending thoracic aortic dissections and aortic aneurysms with TEVAR. If untreated, these aneurysms and dissections may be deadly.

Open surgery was the method of choice in the past for treating thoracic aortic dissections and aneurysms. However, they now favor TEVAR more frequently. This is because, in suitable candidates, TEVAR has a somewhat easier recovery and a decreased chance of significant consequences. To determine your eligibility, your doctor will assess the structure of your blood vessels and other relevant variables.

What does TEVAR treat?

TEVAR is used by surgeons to fix aortic damage because of:

The descending aorta is home to thoracic aortic aneurysms. The segment of the aorta that descends through your chest and enters your abdomen is known as this.

Dissection of the aorta.

Tears or damage from auto accidents and other traumatic causes of serious injury to your chest can result in an aortic transsection.

What needs to be done in advance of a TEVAR procedure?

You and your doctor will discuss how to get ready. You may need to:

Take medication to lower blood pressure and/or cholesterol.

Give quit smoking and using tobacco products.

You should reschedule your regular medication times

Preoperative tests should be done (described below).

Your provider might prescribe testing to assist in organizing your surgery. A computed tomography (CT) angiography is a typical test you might anticipate. A CT angiography can show the size and condition of the arteries your doctor will need to access during TEVAR.

For TEVAR to succeed, you must have enough artery clearance for the catheter to reach your aorta. Providers typically use one of your iliac arteries in the pelvis or femoral arteries in the upper thigh. If these arteries are blocked by plaque or unavailable, the provider will have to find another way in.

Additionally, imaging tests assist your doctor in selecting the appropriate stent graft type and size. In the event of a dissection or transection, the stent graft aids in relining your artery to cover the artery's rip. To reduce the chance of an aneurysm expanding or burst, the stent transplant assists in blocking blood flow to the swollen section of the artery.

Stent graft selection-

The providers select the size and kind of stent graft that best meets your needs. To treat more complicated aneurysms, for instance, medical professionals employ fenestrated stent grafts. Blood can enter arteries that branch off of your aorta through the pores in a fenestrated stent graft. These devices may be required in cases with aneurysms that:

Affect the aortic arch, the curved section of the aorta that joins the ascending and descending segments.

Radiate from your abdomen and chest (thoracoabdominal aneurysms).

Involve the arteries that emerge from your aorta and go to your arms, brain, or intestines.

What takes place in a TEVAR procedure?

Your surgical care team will carry out TEVAR by:

Give you a general or local anesthetic along with a sedative to make sure you're comfortable the entire time.

Lower your risk of spinal injury, one of TEVAR's possible negative effects. One method is to install a lumbar (spinal) drain. This catheter drains cerebrospinal fluid during the procedure. Providers determine whether safety measures are necessary by evaluating each scenario independently.

Make a small skin incision in your groin around the femoral artery to gain access to your arteries.

Once you've crossed the area where your arteries are damaged, insert a guide wire through them.

Help the wounded area by applying the stent graft.

Remove the catheter and leave the stent graft in place. After then, the stent graft expands like a spring to fit against the aortic walls. It functions as a new lining for your aorta, preventing blood from pushing against the weak points in the vessel's walls.

The place in your groin where you made the incision should be sewn and wrapped.

What is the duration of TEVAR surgery?

Usually, TEVAR takes two hours.

During a TEVAR procedure, a stent-graft is inserted via a catheter into the aneurysm site. It acts as a fresh aortic lining.

What happens after this procedure?

One or two days after your procedure, you might need to stay in the intensive care unit (ICU). The treated area will determine how this changes. Your medical team will carefully monitor you and search for any signs of concern. You will then be moved to a regular hospital room for continued monitoring. It should take you a day or a week to get back home.

What are TEVAR's advantages?

TEVAR is generally preferred by healthcare professionals over open surgery because

• It has the same success in solving the issue as open surgery.
• Enjoys a more rapid and simple recovery, requiring less time in the hospital.
• It has a decreased chance of fatalities or major problems.
• Does not necessitate an open chest incision, or thoracotomy.
• Reduces pain and blood loss.
• Has a decreased risk of end-organ ischemia, which is the loss of blood flow that damages organs.

How well does this process work?

The survival rate of TEVAR is higher than that of open surgery. 98% of patients with TEVAR treatment recover fully, compared to 88% to 94% undergoing open surgery. Treatment outcomes are best achieved by aorta centers that specialize in aortic disease.

What side effects and hazards does TEVAR present?

There are some risks associated with surgery. Among TEVAR's possible threats are:

• The graft moving.
• Due to a lack of blood supply to the spine, spinal ischemia can cause paraplegia, or paralysis of your legs.
• Heart attack.

Your provider can discuss reducing the risks associated with this surgery with you.

How long does recovery take?

After your procedure, you will probably leave the hospital and return home in a day or two. When your doctor tells you to start doing regular activities again, heed their advice. Generally speaking, you might need to:

• Give driving a week or two's rest.
• Showers and sponge baths are fine until your groin wounds heal. Avoid baths during this time.
• For a week or two, refrain from lifting more than ten pounds.
• Your doctor may also recommend changes to your lifestyle. A healthy diet and more exercise are two of them.

When should I call my healthcare provider?

Call your physician if you have any questions or concerns about your treatment or recovery plan. They can answer your questions and help you feel comfortable throughout the procedure.
