Fenestrated Endografts Q & A

What are fenestrated endografts?

Fenestrated endografts are stents used by the Vascular Associates of San Diego team to repair large or complex aortic aneurysms.

Standard endografts come in regular sizes, which suit most types of aneurysms. Occasionally, however, a patient has a sizable aneurysm or one with challenging anatomy for which a standard graft won't work.

The Vascular Associates of San Diego team has special training and extensive experience in designing custom fenestrated endografts. Using custom grafts enables the team to treat very complex aortic aneurysms that might otherwise require extensive open surgery. Examples include:

  • Thoracic aneurysms involving the aortic arch
  • Thoracoabdominal aneurysms involve both chest and abdomen
  • Aneurysms involving the vessels leading to your kidneys or brain

In cases where surgery isn't possible, using a fenestrated endograft might be the only solution.

What is an aortic aneurysm?

An aortic aneurysm is a bulge in your body's major artery, the aorta. These bulges typically occur in either your abdomen or chest, or sometimes both. Aneurysms may affect any artery, but the aorta is particularly prone to developing them.

The bulge is a sign that there's a weak spot in the artery wall. The artery expands to form a balloon of blood, which may rupture. Many people have aneurysms for months or even years and don’t realize it because they don’t experience any symptoms.

However, if your aneurysm grows big enough and ruptures, it could be fatal. You can undergo screening for aortic aneurysms if you have an increased risk, such as a family history of aneurysms or narrowed arteries (atherosclerosis).

What happens when I have a fenestrated endograft?

Fenestrated endovascular repair (FEVAR) is a similar procedure to thoracic (TEVAR) and abdominal (EVAR) endovascular aneurysm repairs. Your provider at Vascular Associates of San Diego uses the same catheterization techniques to place the stent graft.

FEVAR involves having a stent graft fitted inside the aneurysm. The stent is a mesh tube made of metal that has tiny hooks on it. These hooks attach to the inner walls of your aorta, holding the stent in place where it strengthens the artery wall.

The difference with a fenestrated endograft is that your provider creates holes (fenestrations) in the endograft that prevent the stent from limiting blood flow to vital organs. Your provider customizes the holes in the graft to suit your individual anatomy.
