1 Transrenal E-XL stenting to resolve or prevent type Ia endoleak in the case of severe neck angulation during endovascular abdominal aortic aneurysm repair  Emiliano Chisci, MD, Giorgio Ventoruzzo, MD, Neri Alamanni, PPhys, Guido Bellandi, MD, Stefano Michelagnoli, MD  Journal of Vascular Surgery  Volume 57, Issue 5, Pages (May 2013) DOI: /j.jvs Copyright © 2013 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Pre- and postoperative computed tomography (CT) scans showing the challenging angulated proximal aortic neck and the remodeled neck following endovascular repair. In both case 1 (A and B) and case 2 (C and D), the follow-up CT scans show the absence of any endoleak and the patency of all visceral and renal arteries.

3 Fig 2 Intraoperative images for case 1. A, Type Ia endoleak postballooning; B, placement of the E-XL stent (Jotec GmbH); C, resolution of the endoleak at the completion angiography. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2013 Society for Vascular Surgery Terms and Conditions

4 Fig 3 Bidimensional computer models of abdominal aortic aneurysms (AAAs) were built from angio-computed tomography (CT) scan data. Each angio-CT image was coupled with a computational fluid dynamics evaluation performed using an open source software (CSC Elmer, ElmerSolver, CSC Institute of Technology, Espoo, Finland). Images of cases 1 (A-D) and 2 (E-H), showing both anatomic and hemodynamic remodeling after endovascular repair.
