Thoracic Endovascular Aortic Repair (TEVAR)

Thoracic Endovascular Aortic Repair (TEVAR) is a minimally invasive procedure to repair thoracic aortic aneurysms (TAAs).

The aorta exits the heart and carries blood to all the organs and the rest of the body. After leaving the heart, the aorta branches to the arms and the brain before running down the back of the chest into the abdomen. The aorta forks at the level of the belly button into branches that extend down each leg. To repair the aorta, doctors place a stent graft device through a small hole in the groin. This device is made of a fabric-covered metal mesh, which is fully opened under x-ray. The device repairs the diseased aorta and helps to keep it open and allow blood to flow properly to the rest of the body. Depending on the type of disease, the TEVAR procedure usually provides a cure.
