title: Endograft fabric disintegration simulating a type II endoleak.
abstract: OBJECTIVE
  To report a case of endograft disintegration misinterpreted as a type II endoleak.
  
  
  METHODS
  An 86-year-old man underwent successful Vanguard stent-graft implantation for a 49-mm abdominal aortic aneurysm. At 1 month, a distal type I endoleak was repaired, but another endoleak thought to arise from the lumbar or inferior mesenteric arteries remained. Multiple interventions to embolize the feeding arteries were unsuccessful, and the endoleak persisted. At 1 year, the leak was still present, and the aneurysm had increased to 69 mm. After failing to demonstrate the source of the leak radiographically, surgery was performed. At operation, the endoleak was traced to small holes in the graft fabric. The endograft was removed without difficulty, and the flow was re-established with an aortobi-iliac woven graft.
  
  
  CONCLUSIONS
  Chronically implanted stent-grafts can show signs of failure that are confusing or misleading. Correct diagnosis of endoleaks may be difficult, but every effort must be made to identify their source. It is vital that no enlarging aneurysm be left untreated.
