Late Surgical Conversion After Thoracic Endograft Failure due to Fracture of the Longitudinal Support Wire

Abstract

PURPOSE: To report complications from a thoracic endograft wire fracture and early experience with elective conversion after thoracic endografting. CASE REPORT: A 43-year-old man underwent urgent endovascular repair of a symptomatic post-traumatic thoracic aneurysm in 1999. The patient had been involved in a car accident 14 years before. He developed clinical and radiological signs of graft infection 46 months after stent-graft implantation. Multidetector computed tomography confirmed a fracture of the longitudinal support wire in the Excluder thoracic stent-graft. Additionally, radiological signs of suspected endograft infection were described. Due to concerns over a potential chronic infection, the stent-graft was successfully excised, and a polyester graft was implanted 50 months after primary endovascular repair. CONCLUSIONS: Recognition or strong suspicion of endograft infection requires conversion with removal of the device. Long-term follow-up after endografting is necessary to assess material fatigue that undermines the durability of these implants.
