“…Device-induced aneurysm sac significant changes might alter the device integrity. 20,21 Improved device designs more prone to inducing significant AAA exclusion might also be more likely to be crushed by the aneurysmal sac collapse together with loss of patency. In our study, iliac branch occlusions were more likely found in aneurysms with any shrinkage; 14 asymptomatic occlusions occurred in the persisting shrinkage group.…”

“…However, to date, the main issue of EVAR remains stent graft (SG) durability. Secondary interventions after 5 years are required in up to 22% of abdominal aortic aneurysms because of endoleaks, stenosis or thrombosis of the SG, and failure of the SG components [1][2][3][4][5][6]. Despite much more limited number of reports, complications following endovascular repair of iliac aneurysms are similar [7,8].…”

The mechanical behavior of aortic stent grafts plays an important role in the success of endovascular surgery for aneurysms. In this study, finite element analysis was carried out to simulate the expansion of five marketed stent graft iliac limbs and to evaluate quantitatively their mechanical performances. The deployment was modeled in a simplified manner according to the following steps: (i) stent graft crimping and insertion in the delivery sheath, (ii) removal of the sheath and stent graft deployment in the aneurysm, and (iii) application of arterial pressure. In the most curved aneurysm and for some devices, a decrease of stent graft cross-sectional area up to 57% was found at the location of some kinks. Apposition defects onto the arterial wall were also clearly evidenced and quantified. Aneurysm inner curve presented significantly more apposition defects than outer curve. The feasibility of finite element analysis to simulate deployment of marketed stent grafts in curved aneurysm models was demonstrated. The study of the influence of aneurysm tortuosity on stent graft mechanical behavior shows that increasing vessel curvature leads to stent graft kinks and inadequate apposition against the arterial wall. Such simulation approach opens a very promising way toward surgical planning tools able to predict intra and/or post-operative short-term stent graft complications.

“…Endoleak, graft migration, and aneurysm sac enlargement constitute the remaining shortcomings of endovascular aneurysm repair and underlie the observed loss of comparative clinical benefit during long-term follow-up. [3][4][5][6] The Nellix device (Endologix, Irvine, Calif) was developed with recognition that many of the complications of endovascular aortic aneurysm repair stem from inadequate isolation of the native aortic wall from pressurized blood flow. The highly differentiated Nellix platform uses polymer-filled polyurethane EndoBags surrounding balloon-expandable stents covered with expanded polytetrafluoroethylene and stabilizes the aneurysm sac by completely filling and sealing the blood flow lumen, hence the name EndoVascular Aneurysm Sealing (EVAS) system.…”

This first multicenter postmarket report of the Nellix device for infrarenal abdominal aortic aneurysm repair demonstrates satisfactory results during the initial learning phase of this new technology. The rate of aneurysm exclusion was high, and frequency of complications was low. More definitive conclusions on the value of this novel device await the results of the ongoing Nellix EVAS FORWARD Global Registry and the EVAS FORWARD investigational device exemption trial.
