Brief summary

The Zenith® p-Branch® and Zenith® Fenestrated AAA Endovascular Graft Single-Center Study is a clinical trial approved by US FDA to study the safety and effectiveness of the Zenith® p-Branch® and Zenith® Fenestrated AAA Endovascular Graft in the treatment of abdominal aortic aneurysms.

Interventions

DEVICEZenith® p-Branch® or Zenith® Fenestrated AAA Endovascular Graft

Instead of making a large incision in the chest, the physician makes a small incision near each hip to insert, and guides the study device(s) into place in the aorta.

MeasureTime frameDescription
Technical Success:Immediately post graft deploymentSuccessful access of the aneurysm site and deployment of the Zenith® Fenestrated AAA Endovascular Graft or the Zenith® p-Branch™ in the intended location. The endovascular graft and all vessels targeted with fenestrations must be patent at the time of deployment completion as evidenced by intraoperative angiography
Procedural SuccessWithin 30 days post graft deploymentTechnical Success, with all of the following at post-procedure (within 30 days): * No type I or type III endoleaks; * No procedure related serious adverse events or major complications; * Patency of the endovascular graft and all vessels targeted with fenestrations as evidenced by CT scan, angiography or by duplex ultrasound in those patients experiencing renal failure or otherwise unable to undergo contrast enhanced CT scan.
Treatment Success12 monthsProcedural Success, with all of the following at 12 months: * No type I or type III endoleaks; * No serious adverse events or major complications; * No aneurysm enlargement greater than 0.5 cm; * Patency of the endovascular graft and all vessels targeted with fenestrations as evidenced by CT scan, angiography or by duplex ultrasound in those patients experiencing renal failure or otherwise unable to undergo contrast enhanced CT scan.
