Clinical Outcomes and Quality of Life Measures in Patients Treated for Complex Abdominal, Thoracoabdominal and Aortic Arch Aneurysms or Dissections With Fenestrated and Branched Stent Grafts
Baylor College of Medicine
Summary
The purpose of this study is to gather safety and effectiveness of the Zenith t-Branch and customized physician-specified stent-graft with a combination of fenestrations and/or branches to repair aortic aneurysm.
Description
This is a traditional device feasibility study intended to generate preliminary safety and efficacy information that may be used to plan an appropriate future study, or to inform further product development. Subjects will have been diagnosed with a bulge or aneurysm in their aortic arch and or abdominal aorta, which is the blood vessel in the abdomen (belly) that supplies blood to most of the lower body including major organs and the legs. The Zenith t-Branch and physician-specified fenestrated and branched endovascular graft is a tubular graft made of polyester fabric sewn to stainless stee…

Interventions
- DeviceCAAA and TAAA Arm
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). One or more than one of the study devices including the Zenith® Fenestrated AAA Endovascular Graft, Zenith® t-Branch Endovascular Graft, Patient-Specific Thoracoabdominal Graft, Patient-Specific Distal Bifurcated Component, and Zenith® Branch Endovascular Graft-Iliac Bifurcation will be implanted. The arteries to the liver, intestine, and kidneys will have a stent (small tubular stainless steel structures) to help keep the arteries open and aligned with the fenestrations or branches.
- DeviceAortic Arch Aneurysm Arm
The Zenith® Arch Branch 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.
