Abstract:
When one compares the potential advantages of endovascular aortic repair with respect to traditional open repair, it would seem logical that extension into the paravisceral aorta would be easily justified, given the complexity of open aortic repair and its associated complications. Eight years have transpired between trial initiation and Food and Drug Administration approval of the first fenestrated device in the United States for the treatment of juxtarenal aneurysms. While there are only a few centers in the United States with substantial experience performing fenestrated and branched endovascular aortic repair, there is a diverse experience outside the United States that has been gained over the past decade. It is through the experience of these centers that the technical and procedural complexities of complex endovascular aortic repair has been solved and provide the foundation that has allowed aortic specialists to move endovascular therapy into the paravisceral aorta with fenestrated and branched endovascular aortic repairs.
