Purpose: To describe the novel use of an Amplatzer occluder device to seal a secondary endoleak arising at a scallop in a fenestrated stent-graft. Case Report: A 67-year-old man with comorbidities precluding standard endovascular repair of a pararenal aortic aneurysm was treated with a fenestrated endoprosthesis containing one fenestration for the left renal artery and one scallop for the celiac trunk; the right renal and superior mesenteric arteries were occluded at presentation. Interval imaging at 2 years showed a proximal type I endoleak at the celiac trunk scallop associated with expansion of the aneurysm sac. Attempted repair with an aortic extension cuff and a chimney stent was unsuccessful. An Amplatzer Patent Foramen Ovale occluder device was deployed across the endoleak to provide aneurysm sac exclusion, which has been maintained at 6-month follow-up. Conclusion: Treatment of a secondary type I endoleak after implantation of a fenestrated endoprosthesis is challenging. The novel use of an Amplatzer occluder in this setting may be applicable to other situations in which an endovascular solution is desirable for complications of complex endovascular aneurysm repair.
