Abstract:
Re-intervention on abdominal aortic aneurysm treated by endovascular aortic aneurysm repair for complications such as endoleak, graft migration, and graft failure is relatively common. However, re-do endovascular aortic aneurysm repair can be complex, as the failed graft still resides within the vessel. In addition, some re-do endovascular aortic aneurysm repairs call for an advanced custom graft, which can further increase the complexity and technical skill required. We describe a case of a 15-year-old endovascular aortic aneurysm repair originally implanted in a 71-year-old man, followed by three separate complications requiring intervention. We describe important procedural decisions taken into consideration when presented with failure of an older graft.
