Clinical Outcomes and Radiation Safety After Endovascular Repair of Complex AAAs Using Fenestrated- Branched Devices
brief summary
The purpose of this study is to assess the clinical outcomes and radiation of the use of off-the-shelf and custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal, thoracoabdominal and arch aortic aneurysms in patients having appropriate anatomy. The study consists of three cohorts. The first 2 cohorts are the continuation of the current IDE study. The first cohort is aimed to assess the use of custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal and type IV thoracoabdominal aortic aneurysms in standard and high-risk patients having appropriate anatomy (Fenestrated-CMD cohort). The second cohort (Type I-III thoracoabdominal cohort) includes standard and high-risk patients with type I- III thoracoabdominal aneurysms that require the use of branched/fenestrated CMDs, or, in selected cases, the Zenith Thoracoabdominal Branch (Zenith® t-Branch™) device. Finally, the third cohort (the Arch cohort) will include 25 high-risk patients with aortic arch aneurysms treated by patient-specific stent-grafts with one to three inner branches or a scallop
detailed description
This study is a prospective, single center, non-randomized, triple-cohort study. For the Fenestrated-CMD cohort a total of 350 patients will be enrolled. For the type I-III thoracoabdominal cohort, a total of 250 patients will be enrolled. For the Arch cohort, 25 patients will be enrolled. CMDs will be used primarily. Off-the-shelf devices will be used in urgent cases and when the waiting period for design and manufacturing of a CMD may not be considered acceptable. Staged endovascular repair will be used for type I, II and III TAAAs and for concurrent arch and TAAAs, unless the condition of the patient requires a single stage endovascular repair. A separate subgroup analysis of patients undergoing procedures with off-the-shelf devices will be performed.
