摘　　要：目的回顾性分析经皮椎体后凸成形术后CT显示骨水泥的渗漏率、渗漏位置及并发症。资料与方法搜集经皮椎体后凸成形术患者资料301例。选择其中有术后CT和X线检查的患者资料33例,后凸成形术椎体共55个,其中胸椎19个,腰椎36个。结果 CT显示骨水泥渗漏较X线平片敏感,其局部骨水泥渗漏发生率为61.82%(34/55)。骨水泥渗漏类型有椎旁静脉20处、椎管内13处、椎间盘13处、椎旁软组织4处。最常见的渗漏位置为椎旁静脉(达58.82%,20/34)。同一椎体也可有不同渗漏类型同时存在。出现肺栓塞2例。结论经皮椎体后凸成形术最常见的骨水泥渗漏位置为椎旁静脉,CT对骨水泥椎管内渗漏的显示具有重要的临床价值。Objective To investigate the value of CT in displaying incidence,site of local leakage,and complications of bone cement after percutaneous kyphoplasty.Materials and Methods 301 cases underwent percutaneous kyphoplasty.Among them,33 cases（55 vertebra,including 19 thoracic and 36 lumbar vertebra）performed follow up CT scan.ResultsThe rate of local leakage of bone cement was 61.82%（34/55） showed on CT images.CT images was more sensitive than X ray in detection of cement leakage.Of 55 vertebra treated by kyphoplasty,cement leaked into the veins（n=20）,epidural space（n=13）,disk space（n=13） or paravertebral soft tissues（n=4） were showed on postoperative CT images.The most common sites of local leakage was perivertebral vein with the rate of 58.82%（20/34）.Several leakage types could exist in same vertebrae.Two cases of pulmonary cement embolism developed after kyphoplasty.Conclusion The most common sites of local leakage was perivertebral vein.CT has important clinical value in displaying bone cement leakage.
