Branched Thoracic Endovascular Grafts for the Treatment of Thoraco-abdominal Aortic

An investigator-initiated, prospective, consecutively enrolling, non-randomized single institution clinical evaluation of the safety and effectiveness of branched and fenestrated-branched endovascular stent grafts to preserve branch vessels when used in the treatment of patients with thoraco-abdominal aortic aneurysms. The study evaluates non-FDA-approved off the shelf and custom made branched and fenestrated-branched stent grafts manufactured by Cook Medical. The primary objectives of this study are to determine whether fenestrated-branched and branched endovascular grafts are a safe and effective method of treating patients with thoraco-abdominal aortic aneurysms.
