Evaluation of Visceral Function Following Endovascular Aortic Aneurysm Repair Using Branched Stent- Grafts

This study will evaluate the effect of endovascular repair of thoracoabdominal aortic aneurysms (Types I-IV) on visceral function or aortic arch aneurysms using custom manufactured and off the shelf stent grafts. Specifically, the device orientation and configuration will be evaluated with respect to renal function. Since detailed CT scan imaging will be performed prior to and after endovascular repair, critical data concerning each branched vessel length, tangential orientation from the aorta, angle of incidence, and diameter can be determined. This information can then be coupled with hemody…
