We report the case of a 51-year-old woman who underwent kyphoplasty with polymethylmethacrylate for painful compression fracture of the third lumbar vertebra. Infiltration of cement into the inferior vena cava, noted intraoperatively, was confirmed with postoperative CT scan. A Greenfield filter was placed to prevent cardiopulmonary embolization of the fragment. On follow-up x-rays, the cement fragment was found to have detached and embolized into the vena cava filter. Endovascular technique was used to retrieve it to the common femoral vein with subsequent successful removal of the crescent-like fragment with operative exploration. Patient was asymptomatic at four-week follow-up visit.
我们报告了一例 51 岁女性患者，因第三腰椎疼痛性压缩性骨折接受了聚甲基丙烯酸甲酯骨水泥成形术。术中发现水泥渗透到下腔静脉，术后 CT 扫描证实。放置了 Greenfield 滤器以防止碎片引起心肺栓塞。随访 X 线片发现，水泥碎片已脱落并栓塞至腔静脉滤器内。采用血管内技术将其取回至股总静脉，随后通过手术探查成功取出新月形碎片。患者在四周随访时无症状。
