Abstract

Patients with aneurysms with short or angulated necks and those with involvement of the renal, visceral, and hypogastric arteries may not be candidates for endovascular treatment using infrarenal stent graft. Fenestrated stent grafts with reinforced fenestrations permit the incorporation of the visceral and renal arteries into the endovascular repair enabling an adequate proximal sealing zone. These devices require a 6-week to 8-week period for customization and are not currently commercially available in the United States. Modified fenestrated stent grafts may have a future role in the compassionate treatment of selected high-risk patients with complex aneurysms who otherwise would not have access to a manufactured fenestrated stent graft, or for those in need of urgent or emergent repair because of impending or contained ruptured, rapidly expanding or excessively large aneurysm. The authors have used modified fenestrated stent grafts selectively in patients with large aortoiliac, juxtarenal, pararenal, or thoracoabdominal aortic aneurysms. In this article, the authors summarize the principles applied for device design and procedure planning, as well as the technique for device modification and implantation.
