Purpose: To assess the feasibility and report preliminary results of ruptured abdominal aortic aneurysm (rAAA) repair with endovascular aneurysm sealing (EVAS), a novel therapeutic alternative whose feasibility has not been established in rAAAs due to the unknown effects of the rupture site on the ability to achieve sealing. Case Report: Between December 2013 and April 2014, 5 patients (median age 71 years, range 57–90; 3 men) with rAAAs were treated with the Nellix EVAS system at a single institution. Median aneurysm diameter was 70 mm (range 67–91). Aneurysm morphology in 4 of the 5 patients was noncompliant with instructions for use (IFU) for both EVAS and standard stent-grafts; the remaining patient was outside the IFU for standard stent-grafts but treated with EVAS under standard IFU for the Nellix system. Median Hardman index was 2 (range 0–3). Two patients died of multiorgan failure after re-laparotomy and intraoperative cardiac arrest, respectively. Among survivors, all devices were patent with no signs of endoleak or failed aneurysm sac sealing at 6 months (median follow-up 9.2 months). Conclusion: EVAS for the management of infrarenal rAAAs appears feasible. The use of EVAS in emergency repairs may broaden the selection criteria of the current endovascular strategy to include patients with more complex aneurysm morphology.

“…3e12 The introduction of the novel technique of endovascular aneurysm sealing (EVAS) with the Nellix system (Endologix, Irvine, CA, USA) offers the potential to mitigate these risks by achieving a better seal at the level of the chimney grafts, and a better incorporation of the chimney grafts into the aortic endoprosthesis. Preliminary evidence to support the applicability of EVAS with chimney grafts (Ch-EVAS) from an in vitro model 13 have been confirmed by reports of successful treatment of juxtarenal aneurysms with this configuration. 14,15 Clearly, these studies provide limited information on the durability of Ch-EVAS across a range of aortic morphology.…”

“…Currently there are only nine published original studies on EVAS [1][2][3][4][5][6][7][8][9] , including two case reports [6][7] and one in vitro study 5 . The aim of this paper is to report our observations on perioperative imaging of specific findings related to the EVAS technique.…”

The authors declare no conflict of interest and no sources of funding. AbstractPurpose. Endovascular aneurysm sealing (EVAS), performed with the Nellix® endoprosthesis, is a new technique to treat patients with infrarenal abdominal aortic aneurysm. We describe findings on post-EVAS imaging, discuss their interpretation, and consider their potential implications on EVAS planning and performance.Methods. We performed a retrospective review of perioperative imaging in consecutive patients undergoing elective EVAS at our centre. We systematically reviewed perioperative imaging specifically looking for endobag collapse, aortic thrombus compression and aortic wall disruption, according to definitions set a priori.
