What is a thoracic endovascular aneurysm repair (TEVAR)?

Vascular specialists can repair aneurysms in the portion of the aorta above the bowel arteries, the thoracic aorta, with a procedure called thoracic endovascular aneurysm repair or TEVAR. This procedure is very similar to that used to repair the upper portions of the aorta (EVAR). During the procedure they insert a catheter into an artery in the groin and, using x-ray guidance, thread the catheter to the damaged area of the aorta. Within the catheter is a stent graft, a tube made of a special synthetic material and a self expanding metal scapholding. At the aneurysm (or dissection) the stent graft is deployed so that it bridges and excludes the thoracic aneurysm. The stent graft provides a reinforced channel for the blood to flow through, reducing the pressure on the damaged area of the artery and helping to prevent a rupture. Patients generally go home within several days.
