Why the study?
Although improvements to the AFX2 stent graft appeared to resolve previous issues, a subset of patients still require secondary open conversion for endograft failure.
Highlights the potential for late failure, including stent fracture and fabric tear, of the AFX2 stent graft requiring secondary open conversion.
Technical improvements and labeling updates of the AFX2 stent graft (Endologix Inc, Irvine, CA) seemed to have solved the known issues of its previous generation (AFX Strata). Although most endograft failures after endovascular abdominal aortic aneurysm repair will be managed endovascularly, a small subset of patients will still require secondary open conversion. Partial or complete endograft removal can be required, mainly dependent on the characteristics of the stent graft previously placed. We have report a case of secondary open conversion for late type Ia/IIIb endoleak due to stent fracture and fabric tear of the AFX2 stent graft 3 years after endovascular abdominal aortic aneurysm repair.
