    Abstract:
    Fatal pulmonary thromboembolism (PTE) following percutaneous vertebroplasty is rare in medical practice. Here, we report the case of a 70-year-old woman who suffered from lumbago with lower extremity pain and lameness and for whom lumbar osteoporotic vertebral compression fractures (L4, L5) were seen on MRI examination. Percutaneous vertebroplasty and posterior vertebral lamina fenestration discectomy were performed. One day later, her condition deteriorated after defecation, and she died suddenly. Pulmonary thromboembolus and deep venous thrombosis in the inferior vena cava were the major findings at forensic autopsy. Due to the rather uncommon components of the thromboembolus (chondrocytes, calcium deposits, and collagen fibers), the pulmonary thromboembolism was attributed to deep venous thrombosis in the inferior vena cava, which was injured during percutaneous vertebroplasty. The present study highlights the conclusion that pulmonary thromboembolism is a rare complication of percutaneous vertebroplasty that should attract the attention of clinical physicians and forensic pathologists.
