Nellix endovascular aneurysm-sealing system: asingle-center experience and review of current evidence.

Abstract

Aims: We report the 6-year results of our use of the Nellix® endovascular aneurysmsealing system. Materials & methods: This is a retrospective review of patients we treated from 2013 to 2019. The outcomes described include technical success rate, mortality, all procedure-related complications, reinterventions, open surgical conversion andsecondary sac rupture. Results & conclusions: A total of 68patients were treated. Mortality was 2.9%. Secondary interventions were carried out for distal embolization (3), stent occlusion (1), pseudoaneurysm (1) and endoleak (5). Open surgical conversion was required in 6.4% of cases. Medium-and long-term complications of EVAS occurred more frequently than expected. Because thedurability of endovascular aneurysm sealing is questionable, strict postoperative surveillance of Nellix is crucial to identify features of failure.
