title: Pseudoaneurysm formation at the site of external iliac artery stents: percutaneous stent-graft treatment.
abstract: OBJECTIVE
  To present a patient who developed an asymptomatic large iliac pseudoaneurysm complicating stent-supported iliac artery recanalization.
  
  
  METHODS
  The pseudoaneurysm was detected in an asymptomatic 69-year-old man during routine angiography 6 months after an uncomplicated procedure to implant 3 overlapping Palmaz stents in an occluded external iliac artery. There was no evidence of stent infection. During a second intervention, the pseudoaneurysm was successfully treated by percutaneous implantation of an EndoPro System I stent-graft. Contrast-enhanced spiral computed tomography at 6 and 12 months confirmed the durability of aneurysm exclusion and the patency of the endoprosthesis.
  
  
  CONCLUSIONS
  Angioplasty-induced pseudoaneurysm is rare and usually asymptomatic, but elective percutaneous stent-graft repair should be considered as the first treatment option.
