Thoracic endovascular aortic repair (TEVAR)
Discover how TEVAR can treat your patients.
Thoracic endovascular aneurysm repair (TEVAR) is a minimally invasive alternative to major open surgery for the repair of the thoracic aorta that results in reduced recovery times and potentially improved survival rates.
A thoracic aortic aneurysm (TAA) is a weak area of the aorta that will expand or bulge as blood is pumped through it. As the TAA grows, the wall of the aorta becomes weaker.
If the TAA continues to grow, it could rupture and this would lead to large amounts of bleeding inside the body. An aneurysm rupture needs immediate medical attention because it can lead to death.
TAAs are divided into three categories based on their location:
Ascending aortic
Aortic arch
Descending thoracic aneurysms (or thoracoabdominal aneurysms)
People are more likely to have a TAA if they1:
Are over 50
Are men
Have high blood pressure
Are smokers
Have a family member with TAA
Most people with a TAA do not have symptoms. For those with symptoms, the most common are:
Hoarseness1
Difficulty swallowing2
Pain in the chest, back, side, or stomach1
The pain may range from mild to severe1
A TAA is often found during a CT scan being done for unrelated reasons.1
Two of the most common methods of repairing TAAs are traditional open surgery and thoracic endovascular aortic repair (TEVAR), which is a minimally invasive alternative.
TEVAR of the thoracic aorta is performed using an endovascular stent graft. The thoracic stent graft is placed within the aneurysm to relieve pressure on the damaged vessel wall by enabling blood flow to bypass the aneurysm.
The minimally-invasive procedure is performed using long, thin tubes (catheters) to deliver the thoracic stent graft into the aneurysm through small incisions in the groin.
In an open surgery, a large incision is made in the chest to treat a lesion by sewing in a fabric vascular graft.
In the TEVAR procedure, a stent graft is inserted into the aneurysm through small incisions in the groin.
