Retroperitoneal Dissemination of Proximal Nitinol Ring Fracture Fragments Following Fenestrated EVAR

Year: 2026

Type: article

Abstract: Clinical ImpactFracture of a proximal sealing stent ring is a rare complication following fenestrated endovascular aortic repair (FEVAR). Even rarer can a proximal stent ring fracture with dislodgement and widespread retroperitoneal dissemination of nitinol fragments. This rare complication, which may manifest as transient abdominal pain, could result in severe clinical sequalae. Therefore, plain abdominal radiography should be considered in patients post-FEVAR presenting with epigastric or abdominal pain to assess stent integrity.
