Complex Abdominal, TAAA, Aortic Arch Aneurysm or Dissections With Fenestrated/Branched Stent Graft

"The Zenith Fenestrated-Branched System is a tubular graft made of polyester fabric sewn to stainless steel stents that keep the graft open. The graft will be inserted through arteries in the leg (called endovascular repair). This procedure uses catheters that go inside the blood vessel to place a stent graft above and below the aneurysm.~The graft includes 1 to 5 small holes (fenestrations) or cuffs (side branches). The arteries to the liver, intestine, and kidneys will be have a stent (small tubular stainless steel structures) to help keep the arteries open and aligned with the fenestrations or branches."

The endovascular graft includes the main aortic arch portion and one to three cuffs (side branches) that allow the graft to be located in the aortic arch. The number of cuffs is decided based on the anatomy of your aneurysm. The arteries in the aortic arch are the innominate artery (Zone 0), left common carotid artery (Zone 1) and the left subclavian artery (Zone 2). These arteries supply the right arm and right side of the brain, the left side of the brain and the left arm, respectively. The main aortic endovascular graft will be connected into the innominate artery, left common carotid artery and left subclavian artery using additional stents into the branch vessels.
