摘　　要：目的探讨经皮椎体成形术(PVP)和椎体后凸成形术(PKP)并发骨水泥肺栓塞的MSCT表现及其临床意义。方法搜集PVP和PKP术后58例患者的胸部MSCT,评价是否并发骨水泥肺栓塞并分析其MSCT表现。结果 58例患者中5例发现骨水泥栓子,发生率约为8.6%,其中肺癌多发椎体转移2例,胃癌多发椎体转移1例,多发骨髓瘤1例,骨质疏松性压缩骨折1例;骨水泥栓子CT表现为肺动脉分支内斑点状、小条状、分支状高密度影,散在或弥漫分布于两肺野。1例左肺动脉主干内见附壁骨水泥栓子,延伸至左肺上叶肺动脉内;3例同时发现椎旁静脉和奇静脉内骨水泥栓子。结论 MSCT可准确显示肺动脉分支内骨水泥栓子。Objective To discuss the MSCT manifestation and clinic significance of pulmonary cement embolism accompanied with percutaneous vertebroplasty（PVP） or percutaneous kyphoplasty（PKP）.Methods 58 patients with percutaneous vertebroplasty（PVP） or percutaneous kyphoplasty（PKP） received thorax MSCT to investigate whether pulmonary cement embolism existed or not and analyze MSCT manifestion.Results Of 58 cases,pulmonary cement embolism was found in 5 cases（8.6%）,in which 2 cases with vertebral metastasis caused by lung cancer,1 case with vertebral metastasis caused by gastric cancer,1 case with multiple myeloma and 1 case with vertebral compression fracture caused by osteoporosis.Pulmonary cement embolism presented spot like,small strip like,branch like,scattered and wide spread high density in both lung fields on CT.1 case of cement embolus was located at left main pulmonary artery attached to vessel wall and extended to left superior pulmonary artery and 3 cases were located at paravertebral venous plexus and azygos vein simultaneously.Conclusion MSCT can accurately demonstrate pulmonary cement embolism.
