title: Type IIIb Endoleak With the Endurant Stent-Graft.
abstract: OBJECTIVE
  To report 2 cases of type IIIb endoleak with the Endurant stent-graft and postulate the cause for the events.
  
  
  METHODS
  A type IIIb endoleak was diagnosed at open conversion for a ruptured aneurysm 4 years after implantation of an Endurant stent-graft. In the other case, the endoleak was diagnosed at angiography 4 years after the Endurant stent-graft was implanted; the stent-graft was relined. In both cases the fabric hole was in the body of the stent-graft at the level of the top of the contralateral limb.
  
  
  CONCLUSIONS
  The cause of the type IIIb endoleaks in these cases was fabric erosion likely due to interaction between the bare metal at the top of the contralateral limb and the fabric of the stent-graft body.
