Thoracic endovascular aneurysm repair (TEVAR) is a minimally invasive procedure used to treat aneurysms in the thoracic aorta, the section of the aorta that runs through the chest. During TEVAR, a stent graft is inserted through a catheter into the aorta, where it is positioned to seal off the aneurysm and prevent rupture. This procedure is performed through small incisions in the groin, which makes it less invasive and offers a quicker recovery time compared to traditional open surgery.

TEVAR is highly effective for treating thoracic aortic aneurysms, reducing the risk of rupture and improving the patient’s long-term health prognosis.
