What does the TEVAR procedure involve?

Thoracic Endovascular Aortic Repair (TEVAR) is a minimally invasive procedure to treat a type B aortic dissection. Under fluoroscopic guidance, a stent-graft is inserted through a small incision in the femoral artery and deployed to seal the entry tear in the aortic wall, redirecting blood flow through the graft. This avoids open chest surgery and reduces trauma, with the entire procedure typically taking two to four hours under general anesthesia.
