Safety and Effectiveness of Physician-Modified Fenestrated and Branched Aortic Endografting for the Treatment of Thoracoabdominal and Pararenal Aortic Aneurysms

Brief Summary

The primary clinical objective of this study is to evaluate the safety and effectiveness of a physician-modified, fenestrated and branched aortic endoprosthesis for the treatment of thoracoabdominal aortic aneurysms (TAAAs). The goal of the primary analysis is to demonstrate both the safety and effectiveness of using a physician-modified fenestrated Cook Zenith Alpha Thoracic Endovascular Graft as compared to previously published results of open surgical replacement of the aneurysmal aorta.
