Prevention of cardiopulmonary embolization of polymethylmethacrylate cement fragment after kyphoplasty with insertion of inferior vena cava filter.

We report the case of a 51-year-old woman who underwent kyphoplasty with polymethylmethacrylate for painful compression fracture of the third lumbar vertebra. Infiltration of cement into the inferior vena cava, noted intraoperatively, was confirmed with postoperative CT scan. A Greenfield filter was placed to prevent cardiopulmonary embolization of the fragment. On follow-up x-rays, the cement fragment was found to have detached and embolized into the vena cava filter. Endovascular technique was used to retrieve it to the common femoral vein with subsequent successful removal of the crescent-like fragment with operative exploration. Patient was asymptomatic at four-week follow-up visit.
