Thoracic Endovascular Aortic Repair (TEVAR)
Request a Cardiologist Referral
The aorta is crucial in delivering oxygen-rich blood from the heart to the rest of the body. As the body’s main artery, it extends from the heart, curves like a cane and branches into smaller arteries that supply essential organs and tissues. A healthy aorta ensures steady circulation, but if it is weakened, it can lead to serious complications.
An aortic aneurysm occurs when a section of the aorta weakens and bulges, increasing the risk of rupture or dissection. A rupture allows blood to leak into the body, while a dissection forces blood between layers of the artery wall, potentially leading to life-threatening consequences. Some of the symptoms, such as chest pain and jaw pain, are generally associated with a heart attack. But sudden stabbing pain in the neck, jaw, abdomen, chest or shoulder, fainting, difficulty breathing and sometimes even sudden weakness may also be symptoms of an aortic event. Clammy skin, nausea, vomiting or shock can also be symptoms of a rupture.
Early detection and treatment are vital for managing an aortic aneurysm. Thoracic endovascular aortic repair (TEVAR) offers a minimally invasive option to restore blood flow and help prevent serious complications.
How Do You Repair an Aortic Aneurysm?
Treatment for a thoracic aortic aneurysm depends on its cause, size, location and growth rate. Some aneurysms require only routine monitoring, while others may need medication or surgery to prevent serious complications. Doctors determine the best thoracic aneurysm treatment based on a person’s condition.
Monitoring and Medication
Regular imaging tests such as echocardiograms and CT scans can help track any changes over time if an aneurysm is small and not growing rapidly. Doctors may also prescribe medications to manage risk factors like high blood pressure and high cholesterol, including:
- Beta-blockers
- Angiotensin receptor blockers
- Statins
Surgical Treatment Options
When an aneurysm reaches a certain size or starts causing symptoms, surgery may be recommended. Options include:
- TEVAR – a minimally invasive procedure where a TEVAR stent graft is placed inside the aorta to reinforce the weakened section and restore proper blood flow
- Open Surgery – if the aneurysm is large or linked to conditions like Marfan syndrome, a surgeon may remove the damaged portion of the aorta and replace it with a synthetic graft
- Personalized External Aortic Root Support (PEARS) – a specialized option for patients with Marfan syndrome. PEARS involves placing a custom-made external sleeve around the aorta to prevent further expansion
The TEVAR procedure is often a preferred, less invasive option for thoracic aneurysm repair over open surgery because it is associated with decreased risk of rupture and improved long-term health outcomes.
What Is TEVAR Surgery?
TEVAR surgery is a minimally invasive aortic repair used to treat conditions affecting the aorta, including aneurysms, dissections, stenosis and trauma-related damage. Reinforcing the weakened section of the artery with a TEVAR stent graft helps restore normal blood flow and reduce the risk of life-threatening complications.
During TEVAR surgery, a surgeon inserts a TEVAR stent graft through a small incision in the groin and guides it to the affected area using X-ray imaging. The procedure includes:
- Injecting dye to create a detailed image of the aorta
- Positioning the TEVAR device over a wire which acts like a rail
- Expanding the stent graft to reinforce the aortic wall
- Confirming proper placement with another imaging test
The TEVAR procedure can be performed under local or general anesthesia, and the small incision is closed with a plug. While some discomfort may occur, this minimally invasive aortic repair generally results in a shorter hospital stay and faster recovery than open surgery.
How Safe Is TEVAR Surgery?
The TEVAR procedure is considered a safe and effective treatment for various aortic conditions, including aneurysms, dissections and traumatic injuries. Since its approval by the U.S. Food and Drug Administration (FDA) in 2005, thoracic endovascular aortic repair has become the preferred approach due to its minimally invasive nature and lower risk of complications than open surgery.
How Long Is TEVAR Surgery?
The TAVR procedure usually takes around two hours to complete.
