Successful Percutaneous Retrieval of Methyl Methacrylate Orthopedic Cement Embolism From the Pulmonary Artery

Vertebroplasty cement embolization into the venous system has long been recognized as a potential complication, but the true incidence of systemic embolization is unknown. Clinical presentations range from patients who are asymptomatic or have incidental findings on imaging to massive pulmonary embolism resulting in death. Optimal treatment is controversial and the natural history is unknown. We present the case of an 85-year-old female undergoing combined laminectomy and vertebroplasty with subsequent pulmonary embolism of the cement which was successfully retrieved from a percutaneous approach.
