Endovascular Repair of Type IIIb Endoleak With the Amplatzer Septal Occluder.

<bold>Purpose: </bold>To report the successful treatment of a type IIIb endoleak with an Amplatzer Septal Occluder.<bold>Case Report: </bold>A 76-year-old man was found to have a type IIIb endoleak in the proximal body component of a fenestrated graft at 4-year surveillance imaging; the leak was associated with rapid aneurysm growth. The anatomy of the graft and position of the fabric defect precluded treatment by relining with a secondary endograft. The defect was demonstrated with catheter angiography, sized with an angioplasty balloon, and repaired using an Amplatzer Septal Occluder. Follow-up imaging at 6 months showed no endoleak and marked reduction in the aneurysm size.<bold>Conclusion: </bold>The Amplatzer Septal Occluder may be considered as an option for managing type IIIb endoleaks.
