Through small incisions in the groin, catheters are used to guide and deliver a stent-graft through the blood vessels to the site of the aneurysm from within the aorta. The stent graft is then deployed in the diseased area of the aorta and "relines" the aorta like a sleeve to divert blood flow away from the aneurysm.
An endovascular stent graft is a fabric tube supported by metal wire stents (also called a scaffold) that reinforces the weak spot in the aorta. By sealing the area tightly with your artery above and below the aortic aneurysm, the graft allows blood to pass through it without pushing on the aneurysm.
Endovascular repair of thoracic aneurysms is generally less painful and has a lower risk of complications than traditional surgery because the incisions are smaller. Endovascular aorta aneurysm procedures also allow you to leave the hospital sooner and recover more quickly after your aorta repair.
Not all aortic aneurysms will qualify for this type of repair.
