Vertebroplasty consists of injection under image guidance of a cement polymer, commonly polymethylmethacrylate, into the vertebral body to improved stability. Vertebroplasty is essentially safety. However whether vertebral compression or (micro)fractures occur during the procedure, the high vascularization and the anatomic network of the paravertebral and extradural venous plexuses, can facilitate migration of cement fragments into the systemic venous circulation. We described the case of cement pulmonary embolism in a 75-year-old-female after vertebloplasty. A chest CT scan showed a multiple and spontaneus hyperdensities suggesting cement pulmonary-emboli. There are different therapeutic approach depending of the clinical severity. For asymptomatic patients clinical surveillance or prophylactic LMWH. Active treatment has been suggested only for symptomatic cases.
椎体成形术是在影像引导下将水泥聚合物（通常是聚甲基丙烯酸甲酯）注入椎体以提高稳定性。椎体成形术基本上是安全的。然而，无论在手术过程中是否发生椎体压缩或（微）骨折，由于椎旁和硬外静脉丛的高度血管化和解剖网络，水泥碎片都可以容易地迁移到体循环静脉中。我们描述了一例 75 岁女性在椎体成形术后发生水泥性肺栓塞的病例。胸部 CT 扫描显示多发且自发的高密度影提示水泥性肺栓塞。根据临床严重程度，有不同的治疗方法。对于无症状患者，临床监测或预防性低分子肝素。仅对有症状的病例建议进行积极治疗。
