Complex Aortic Aneurysm Repair Using Physician Modified Endografts and Custom Made Devices
Andres Schanzer
Summary
The purpose of this study is to evaluate the safety and efficacy of custom made devices, Zenith t-Branch devices and physician modification of FDA approved off-the-shelf endovascular grafts in the treatment of patients with complex abdominal aneurysms, aortoiliac aneurysms, thoracoabdominal aneurysms and aortic arch aneurysms who (1) have anatomy not suitable for endovascular repair using grafts currently marketed in the United States,(2) are deemed unsafe to wait the required time necessary for commercial endograft manufacturing, and (3) are at high risk for open surgical repair. Amendment to the study has created a cohort open to people with connective tissue diseases such as Marfan, Ehlers-Danlos or Loey-Dietz syndromes to enroll in the trial. An additional amendment to the study allows the use of a custom made device to treat an aneurysm in the aortic arch.
Description
Endovascular repair of complex aortic aneurysms is limited by the need to maintain blood flow to the critical organs that receive blood from the aorta, such as the kidneys, liver and intestines. While there are some commercially available devices that may treat some of these patients these devices may not be suitable or available for a given patient. In this study we will use custom made devices manufactured by Cook, Inc, Zenith t-Branch devices and off-the-shelf, FDA approved devices which are altered by creating fenestrations (holes) in the stent graft that allow additional stents to be inse…
