Abstract

Since the introduction of fenestrated endovascular aneurysm repair (FEVAR) in 1996, great advances have been made in endograft development. Custom-made and off-the-shelf fenestrated and branched endografts have been used to treat patients with complex abdominal aortic and thoraco-abdominal aneurysms. Most experience has been gained with the Cook Zenith® fenestrated endograft (Cook Medical Inc., Limerick, Ireland). The Cook Zenith® endograft is customized with fenestrations, (fixed) inner or outer branches, or a combination of them, to cover a wide range of complex aneurysms. There are limitations to the number, location, and size of the fenestrations and to the maximal angulation of the aorta. Because the production of a custom-made fenestrated endograft takes several weeks, and is therefore not available for emergency cases, off-the-shelf fenestrated endograft were developed. One of these grafts was the Endologix Ventana™ (Endologix, Inc., Irvine, California). This endograft was withdrawn from enrollment due to a high reintervention rate. Vascutek Ltd. developed the custom-made Vascutek Fenestrated Anaconda™ endograft (Vascutek Ltd., Inchinnan, Scotland) to treat patients where other endografts were not suitable-like in a more tortuous aorta with an angulation up to 90°. Additionally, the unsupported proximal body enables a high number and large size of fenestrations if needed. First reports of custom-made fenestrated and (inner and outer) branched JOTEC E-xtra DESIGN ENGINEERING (JOTEC GmbH, Hechingen, Germany) for aortic aneurysms seem promising, but larger series need to be reported to be able to draw conclusions. Both custom-made Cook Zenith® and Vascutek Fenestrated Anaconda™ endografts have good reported clinical outcomes with a perioperative mortality between 4.1 and 6.7% and a reintervention rate of <10% at one year. Knowledge on the long-term outcome of both devices is still limited.
