Percutaneous vertebroplasty is frequently used in the treatment of vertebral body fractures due to osteoporosis, vertebral body metastasis, or myeloma. Acrylic cement of polymethylmethacrylate injected into the vertebral body can leak into the paravertebral venous system and reach the pulmonary artery via the azygos vein leading to a cement pulmonary embolism. We are presenting a case of a 78 year old woman who was found to have polymethylmethacrylate pulmonary embolism as a result of vertebroplasty used for vertebral collapse from metastatic breast cancer. The appearance of new intrapulmonary artery tubular opaque density on CXR performed post procedure is highly suggestive of the diagnosis. In this case, we are exploring the importance of clinical and radiographic correlations, as well as evaluation of the hemodynamic and perfusion effect of the cement pulmonary embolism as essential steps in the management of this condition.
经皮椎体成形术常用于治疗因骨质疏松、椎体转移瘤或骨髓瘤导致的椎体骨折。注入椎体内的聚甲基丙烯酸甲酯丙烯酸骨水泥可渗漏至椎旁静脉系统，并经奇静脉到达肺动脉，导致骨水泥肺栓塞。我们报告一例78岁女性患者，因转移性乳腺癌椎体塌陷行椎体成形术后发生聚甲基丙烯酸甲酯肺栓塞。术后胸部X线片上新出现的肺内动脉管状不透明密度影高度提示该诊断。在本病例中，我们探讨了临床与影像学相关性以及评估骨水泥肺栓塞的血流动力学和灌注效应作为该疾病管理重要步骤的重要性。
