Progress on fenestration during thoracic endovascular aortic repair / 浙江大学学报·医学版

ABSTRACT

Endovascular aortic arch repair remains challenging due to the complicated anatomy and the involved vital branches. Off-label techniques emerged during the last decade, including endografts with parallel stents (known as Chimney, Periscope, Sandwich), surgeon-modified endografts, and various other reported techniques. fenestration of standard endografts represents another off-label endovascular means to maintain perfusion to aortic side branches located in the excluded area. Its principle is based on fenestration of an endograft following its deployment inside the vascular system. As data are emerging regarding fenestration, the aim of this article is to review recent progress of technical descriptions, and clinic results of fenestration from the available literature.
