Pulmonary cement embolism after pedicle screw vertebral stabilization
Journal of Emergencies, Trauma and Shock, 08/17/2012
Tonolini M et al. – Pulmonary arterial embolization of polymethylmethacrylate cement, most usually occurring after vertebroplasty or kyphoplasty, is very uncommon following vertebral stabilization procedures. Unenhanced CT scans viewed at lung window settings allow confident identification of cement emboli in the pulmonary circulation along with possible associate parenchymal changes, whereas hyperdense emboli may be less conspicuous on CT–angiographic studies with high–flow contrast medium injection.
