1 Three-dimensional fusion computed tomography decreases radiation exposure, procedure time, and contrast use during fenestrated endovascular aortic repair  Michael M. McNally, MD, Salvatore T. Scali, MD, Robert J. Feezor, MD, Daniel Neal, MS, Thomas S. Huber, MD, PhD, Adam W. Beck, MD  Journal of Vascular Surgery  Volume 61, Issue 2, Pages (February 2015) DOI: /j.jvs Copyright © 2015 Society for Vascular Surgery Terms and Conditions

2 Fig 1 This image demonstrates the method of overlay mark production and use. A, Marks are placed around the origins of the superior mesenteric artery (white arrow) and renal arteries (red arrows). B, The intraoperative overlay of these marks is shown on live fluoroscopy, and the radiopaque markers on the graft can be seen to closely approximate these overlay marks during deployment. C and D, Images are shown for the same patient in a lateral projection. Note that a perfectly orthogonal image of the vessel origin can be obtained by aligning the origin marker such that it appears as a line on the overlay, and this can be aligned before fluoroscopy is initiated, minimizing radiation during adjustment of the C-arm.

3 Fig 2 This figure demonstrates the reduction in (A) radiation exposure, (B) fluoroscopy time, (C) contrast usage, and (D) overall procedural time with use of three-dimensional fusion computed tomography (3D CT) technology in fenestrated endovascular aneurysm repair (FEVAR).
