Pulmonary Palacos embolism: a case report.

Instrumentation with cement-augmented pedicle screws has expanded the therapeutic spectrum. This technique is useful for the palliation of bone metastases and in generalized osteoporosis. Serious complications such as pulmonary embolism have been described following percutaneous vertebroplasty, a frequently used technique. We report the case of a 55-year-old patient with a large central Palacos embolism of the right pulmonary artery after corporectomy of the lumbar vertebrae 3 and 4 and reconstruction using autologous pelvic bone. The large Palacos embolism was removed successfully from the right pulmonary artery with extracorporeal circulation. © Georg Thieme Verlag KG Stuttgart · New York.
