ABSTRACT: Purpose: The Nellix endovascular aneurysm sealing (EVAS) system was introduced in
2010 for infrarenal abdominal aortic aneurysm (AAA) repair. So far one
secondary type 1a endoleak resulting in rupture of the aneurysm has been
reported. Case report: We present a case of a rupture of an infrarenal
aortic aneurysm due to a secondary type 1a endoleak caused by stent migration
14 months after endovascular aneurysm sealing with a Nellix system. Conclusion: Strict adherence to anatomical requirements given by the instructions for use
during patient selection and thorough post interventional surveillance may
reduce the probability of secondary type 1a endoleaks. Furthermore, device
design changes, especially concerning the configuration of the proximal part of
the stent graft, have to be considered.
