Aortic Artery Grafts

Your Care Explained > Devices : Aortic Artery Grafts

Aortic aneurysms may be repaired in one of two ways: with synthetic tubing that bypasses the affected region of the artery, or with a stent—a device to reinforce the artery from the inside.

Which one is most appropriate for you depends on a number of factors, including the size and location of your aneurysm and the size of your arteries, which are smaller in women than in men.

Aortic Graft

A strong, durable, synthetic material, usually Dacron™ or polytetrafluoroethylene, is formed into a tube the size and shape of a healthy aorta. The tube replaces the weakened section of the aorta and allows your blood to pass easily through it. Risks associated with this graft include infection and leaking.

Endovascular Stent Graft

An endovascular stent graft is a woven synthetic tube of Dacron™ or polytetrafluoroethylene supported by a tubular metal web that expands to a pre-established diameter when placed in the artery. The potential complications of endovascular stent grafting include blood leakage around the graft, infection, movement of the graft away from the original location and blocked blood flow through the graft.
