To evaluate the proximal stability of the chimney endovascular aneurysm sealing configuration (chEVAS) during the cardiac cycle by investigating the cardiac pulsatility-induced movement and deformation. We retrospectively analyzed postoperative electrocardiogram-gated computed tomography angiography scans of 11 chEVAS cases (9 primary chEVAS plus 2...

Adverse outcomes observed late in the Nellix EndoVascular Aneurysm Sealing (EVAS) System (Endologix, Inc, Irvine, Calif) investigational device exemption trial prompted refinement of the anatomic instructions for use (IFU). This study aimed to investigate the association of procedural factors during Nellix endograft deployment and patient outcomes....

Chimney endovascular aneurysm sealing (ch-EVAS) could potentially minimize gutter-associated endoleaks in patients with juxtarenal abdominal aortic aneurysms resulting from the use of the conformable endobags surrounding the chimney stent grafts (ch-SGs). The aim of the present study was to quantify the (non)apposition of the endobags in the proxim...

The 1-year results of the use of the Nellix (Endologix Inc, Irvine, Calif) endovascular aneurysm sealing (EVAS) device were initially promising. However, midterm complications including migration and aneurysm growth occurred more frequently than expected, which provided an incentive to refine the instructions for use. Strategies for the management ...

The treatment of juxtarenal abdominal aortic aneurysms is challenging. Open surgical repair is not a viable option for many patients. The use of endovascular aneurysm sealing (EVAS) with chimney grafts (Ch-EVAS) has been proposed as an immediately available, off-the-shelf option for individuals with juxtarenal aneurysms who require urgent treatment...

Endovascular treatment of a type IA endoleak was conducted using a Nellix chimney graft technique for an expanding abdominal aortic aneurysm in an 84-year-old man. During the procedure, a polymer leak occurred from one of the endobags. Postoperatively, the patient developed hemodynamic instability and a swollen leg on the side of the leaking endoba...

The Nellix System (Endologix, Inc, Irvine, Calif) for endovascular aneurysm sealing (EVAS) is a novel approach to abdominal aortic aneurysm treatment and conceptually different from endovascular aneurysm repair, whereby polymer is employed to fill and actively manage the abdominal aortic aneurysm sac. One-year safety and effectiveness results of th...

ObjectiveLate complications after previous endovascular aneurysm repair (EVAR) procedures include type I/III endoleaks causing aneurysm growth and rupture. We reviewed our results from the management of such complications with endovascular aneurysm sealing (EVAS) techniques.MethodsAnalysis of our prospectively maintained aneurysm database was perfo...

Our report aims to alert physicians performing endovascular aneurysm sealing with the Nellix endoprosthesis to the risk of rupture when endobag separation is noticed on computed tomography. Endobag separation when observed with acute presentation of abdominal pain is an indicator of imminent rupture and prompt interventional treatment should be und...
