A thoracic aortic aneurysm is the weakening and enlargement of the aorta, the main vessel that carries blood throughout your body. This type of aneurysm occurs in the thoracic (chest) area. Smokers and those with long-standing uncontrolled blood pressure are at a higher risk of having a thoracic aneurysm. Depending on the size and rate of which the aneurysm is growing, repair may be necessary.
Endovascular repair is a less invasive way of fixing an aneurysm compared to traditional surgery. It avoids the need to perform open surgery, thus, there are fewer risks and complications. During endovascular repair, a thin tube (catheter) is inserted into the artery in your groin and advanced to the aneurysm site. A stent graft is placed which then allows the blood to flow through the graft and prevents the aneurysm from growing.
