Purpose: To describe a technique to rescue intraoperative migration of 1 of the 2 Nellix stents during endovascular sealing of abdominal aortic aneurysms (EVAS).
Technique: The technique requires advancement and inflation of a 10-mm angioplasty balloon into the inlet of the migrated stent via an upper limb approach. Inflation of the balloon allows completion of EVAS without risking the contralateral endobag occluding the inlet of the migrated stent.
Conclusion: This technique allows safe completion of EVAS without compromising stent patency or aneurysm seal and should be considered when intraoperative migration of a Nellix stent occurs despite appropriate precautions.

Introduction: Endovascular aneurysm sealing (EVAS) appeared to be an innovative alternative to conventional endovascular abdominal aortic aneurysm repair. However, high rates of midterm failure of EVAS led to withdrawal of the device from the market. The study aim was to report midterm outcomes of patients treated with EVAS alone or associated with chimneys (Ch-EVAS) and the management of their complications.

Objective: To understand possible reasons for poor durability of the Nellix (Endologix Inc., Irvine, USA) endovascular aneurysm sealing (EVAS) device.
Materials And Methods: 21 Nellix endoprostheses explanted for endoleaks and migration underwent visual examinations of stent structures and instrumental examinations of the polymer endobags on 4 devices.

Endovascular aortic aneurysm sealing (EVAS) with the Nellix endograft was initially considered a groundbreaking and acceptable alternative to conventional endovascular aortic aneurysm repair, with encouraging initial results. However, long-term follow-up has revealed a high incidence of endograft-related complications, such as caudal migration and type Ia endoleaks, indicating the need for reintervention. Managing failed EVAS remains challenging and is an ongoing topic of discussion, especially for high-risk patients.

Background: The Nellix endovascular sealing system (EVAS) was a unique concept with regard to its sealing concept that failed, related to high migration rates. We investigated the changes in aortoiliac morphology during the cardiac cycle before and after EVAS using electrocardiography (ECG)-gated CT.
Methods: Eight patients scheduled for EVAS were prospectively enrolled.
