Pulmonary Polymethylmetacrylate Embolism: A Rare Complication of Percutaneous Vertebroplasty

Percutaneous vertebroplasty is a minimally invasive surgical technique involving transpedicular injection of polymethylmetacrylate into the vertebral body. The aim of this procedure is to enhance the mechanical strength of a pathologically changed vertebra. Currently, the method is most often used for painful osteoporotic vertebral fractures, aggressive haemangiomas, necrotic lesions and spinal tumours, particularly the metastatic ones. Although this method is less invasive, relatively straight-forward and effective, there may be complications. The authors present the case of a 70-year-old woman who, on the second day after surgery, developed a rare symptomatic pulmonary polymethylmetacrylate embolism after percutaneous vertebroplasty performed for osteoporotic fractures of the lumbar spine.
