Update on techniques and results of fenestrated stent-grafts for treatment of juxtarenal AAA

The technique of fenestrated endografting has allowed for the extension of stent-grafts into areas of the aorta containing branches, and thus, enables the treatment of juxtarenal and thoracoabdominal aneurysms with endovascular techniques. Herein, we describe the techniques and results from a single-center study at the Cleveland Clinic. Although complex, the techniques are evolving and simplifying. Early and midterm results from specialist centers are encouraging. This technique provides an endoluminal option for some of the 40% of all abdominal aortic aneuryms (AAAs) who are precluded from conventional endovascular repair, many because of inadequate neck length.
