Thoracic Endovascular Aortic Repair (TEVAR)
TEVAR is a less invasive surgery that uses a stent to repair a portion of the aorta, the main blood vessel that carries blood from your heart to your vital organs. This surgery is used to treat an aortic aneurysm, or enlargement of the aorta in the descending thoracic (chest) and abdominal (belly) areas. TEVAR is also called endovascular stent-grafting or endovascular aortic surgery.
Some patients may be eligible for this less invasive treatment, while others will be better candidates for traditional open surgery.
In this operation, small incisions are made in the groin, and catheters are inserted in the leg arteries. Using live X-rays, a man-made (synthetic) tube, or graft is placed inside the aorta's enlargement (aneurysm) or dissection. This graft is composed of thin material covering a flexible frame, or stent, and seals off the portion of the aorta.
After stent grafting, blood travels within the stent graft, forming a "tube within a tube." The diseased part of the aorta is protected from growing larger.
TEVAR can also be used in combination or "hybrid" operations, where standard surgical replacement is performed for part of the aorta, and then a stent-graft is used for the remainder.
Recovery after TEVAR is usually more rapid than after traditional open-chest aortic repair. In general, patients that undergo TEVAR recover smoothly and are able to leave the hospital within a few days. Close follow-up with the Aortic Center and additional scans are necessary over the next several months.
Where is TEVAR Performed?
TEVAR surgeries are performed in one of two places: the cardiovascular operating room (also called the CV OR) or in the interventional radiology suite. These procedures are done by a combined team of physicians including a cardiothoracic surgeon, a vascular surgeon and an interventional radiologist.
