Endovascular stent grafting, or endovascular aneurysm repair (EVAR), is a surgical procedure done inside of your aorta using a thin tube called a delivery catheter. Unlike open surgery, which involves a long cut in your abdomen, endovascular surgery requires only two small incisions in the area of your groin.

An endovascular aneurysm repair procedure can save your life. Healthcare providers use tiny punctures to insert special devices called stent grafts. The grafts create a new lining for your artery, lowering the risk of a rupture.

The stent graft is a tube made of a thin metal mesh (the stent), covered with a thin polyester fabric (the graft). The tube is collapsed so it is narrow and can fit through your blood vessel. When the stent graft reaches the aorta, it is opened up and fastened in place.

A stent graft is a small metal coil or mesh tube that is placed in an artery thickened with a buildup of plaque which has decreased the flow of blood and oxygen to vital body organs and extremities. This condition is called atherosclerosis .

Stent grafts are a collapsible hybrid product composed of either PET or ePTFE with stents providing for radial support; they are delivered intravascularly to patients’ large vessels, in the same way as are cardiovascular stents.

2025年1月2日 · The stent-graft consists of a graft that provides a conduit for blood flow and a stent that anchors the graft to the aorta and provides structural support for the graft material. The aim is to divert blood flow into the graft, thereby bypassing the aneurysm.

Endovascular stent grafting is a type of cardiac/aortic surgery to repair aneurysms. This procedure is also known as endovascular aneurysm repair (EVAR). An aneurysm is a weak, bulging spot in the artery wall.

2022年5月31日 · The purpose of stent grafts is different from stents for blocked arteries. Aneurysms are weak areas of the blood vessels. Stent grafts have a fabric cover to strengthen the artery and keep blood flow from pushing against the weakened blood vessel.

Then, using an x ray to see the artery, the surgeon threads the graft (also called a stent graft) into the aorta to the aneurysm. The graft is then expanded inside the aorta and fastened in place to form a stable channel for blood flow.

Endovascular stent grafting, or endovascular aneurysm repair (EVAR), is a newer form of treatment for abdominal aortic aneurysm that is less invasive than open surgery. Endovascular stent grafting uses an endovascular stent graft to reinforce the wall of the aorta and to help keep the damaged area from rupturing.
