title: CT-guided percutaneous embolization of a lumbar artery maintaining a type II endoleak.
abstract: OBJECTIVE
  To demonstrate the possibility of percutaneous embolization of a type II endoleak guided by computed tomographic (CT) fluoroscopy.
  
  
  METHODS
  A type II endoleak maintained by a hypertrophic fourth lumbar artery failed to occlude spontaneously 7 months after stent-graft deployment for endovascular repair of an infrarenal abdominal aortic aneurysm. A percutaneous procedure was performed to eliminate the endoleak using needle puncture and embolization under CT fluoroscopic guidance. The sagittal diameter of the aneurysm sac, which had remained constant after initial endovascular exclusion, shrank from 5.2 to 4.8 cm in the 3 months following embolization.
  
  
  CONCLUSIONS
  Percutaneous embolization of lumbar branches guided by CT fluoroscopy may be an alternative to other therapies for type II endoleaks.
