“…Analyzing the English literature, we did not find other similar articles relating to a spontaneous detachment of part of the Nellix stent resulting in the displacement of the endoprosthesis with consequent reperfusion of the aneurysm sac; we have only found one Nellix endobag rupture. 16…”

Purpose: Despite encouraging early results, mid- and long-term follow-up of endovascular aneurysm sealing (EVAS) has shown increased rates of failure mainly associated with endoleak detection and progressive bag separation with aneurysm reperfusion. Case Report: We present the first case of a Nellix endograft stent fracture detected in a 91-year-old male patient, presenting with widespread abdominal pain, 7 years after elective treatment of an abdominal aortic aneurysm by EVAS. Considering the sudden and unexpected nature of the event, an in-depth analysis of the possible causes of this structural failure has been performed. Conclusion: Material fatigue could be another significant cause of late EVAS failure and should be carefully assessed in addition to endoleak detection during follow-up. Clinical Impact The case presented in this article further underlines the importance of a strict long term follow-up protocol in every patients who underwent EVAS.
