What Is An Endovascular Stent Graft? Abdominal Aortic Aneurysm (AAA)


Endovascular stent grafting is for the treatment of an abdominal aortic aneurysm (AAA). This may be considered by a doctor for repair of an aneurysm in the aorta.

Treatment for abdominal aortic aneurysm is open surgery. In this procedure, the section of the vessel where the aneurysm has formed is replaced with a synthetic graft.

An alternative to open surgery for abdominal aneurysm repair is a minimally invasive procedure called endovascular stent grafting. This is also referred to as endovascular aneurysm repair (EVAR).

Endovascular stent grafting is called "minimally invasive," because, the stents used in endovascular stent grafting are designed to be placed inside the area of the abdominal aortic aneurysm without removing part of the aorta.

Talk to Your Doctor

It is very important that any treatment alternatives for aortic aneurysms are discussed with a doctor. A doctor can provide details about the endovascular stent grafting procedure and what the surgery involved.
