title: Percutaneous extraction of cement leakage after vertebroplasty under CT and fluoroscopy guidance: a new technique.
abstract: OBJECTIVE
  We report a new minimally invasive technique of extraction of cement leakage following percutaneous vertebroplasty in adults.
  
  
  METHODS
  Seven adult patients (five women, two men; mean age: 81 years) treated for vertebral compression fractures by percutaneous vertebroplasty had cement leakage into perivertebral soft tissues along the needle route. Immediately after vertebroplasty, the procedure of extraction was performed under computed tomography (CT) and fluoroscopy guidance: a Chiba needle was first inserted using the same route as the vertebroplasty until contact was obtained with the cement fragment. This needle was then used as a guide for an 11-gauge Trocar t'am (Thiebaud, France). After needle withdrawal, a 13-gauge endoscopy clamp was inserted through the cannula to extract the cement fragments. The whole procedure was performed under local anesthesia.
  
  
  RESULTS
  In each patient, all cement fragments were withdrawn within 10 min, without complication.
  
  
  CONCLUSIONS
  This report suggests that this CT- and fluoroscopy-guided percutaneous technique of extraction could reduce the rate of cement leakage-related complications.
