title: Embolization of an internal iliac artery aneurysm after image-guided direct puncture.
abstract: OBJECTIVE
  To evaluate the feasibility, safety, and efficacy of embolization of internal iliac artery aneurysm (IIAA) after percutaneous direct puncture under (cone-beam) computed tomography (CT) guidance.
  
  
  METHODS
  A retrospective case series of three patients, in whom IIAA not accessible by way of the transarterial route, was reviewed. CT-guided puncture of the IIAA sac was performed in one patient. Two patients underwent puncture of the IIAA under cone-beam CT guidance.
  
  
  RESULTS
  Access to the IIAA sac was successful in all three patients. In two of the three patients, the posterior and/or anterior division was first embolized using platinum microcoils. The aneurysm sac was embolized with thrombin in one patient and with a mixture of glue and Lipiodol in two patients. No complications were seen. On follow-up CT, no opacification of the aneurysm sac was seen. The volume of one IIAA remained stable at follow-up, and the remaining two IIAAs decreased in size.
  
  
  CONCLUSIONS
  Embolization of IIAA after direct percutaneous puncture under cone-beam CT/CT-guidance is feasible and safe and results in good short-term outcome.
