Late Type III endoleak and graft failure of an Ancure stent-graft.

The authors report a case of a delayed type IIIb endoleak with sac expansion 6 years after an endovascular repair of an abdominal aortic aneurysm with an Ancure bifurcated stent-graft. The presumed etiology of the leak was secondary to erosion of the main body graft material by metal stents placed within the graft to correct kinking of the iliac limbs at the index operation. The endoleak was successfully treated by endovascular means with an aortouni-iliac device, contralateral iliac plug followed by a femoral-to-femoral bypass graft.
