摘要

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.
