摘要
背景:通过经皮穿刺向椎体内注射骨水泥可增强椎体强度及稳定椎体,达到止痛目的,但骨水泥可能在注入过程中渗漏入椎旁血管,并通过腔静脉系统回流至右心室进而进入肺动脉造成肺栓塞。目的:探讨经皮椎体成形中骨水泥椎旁血管渗漏与骨水泥性肺栓塞的关系。方法:回顾性分析骨质疏松性椎体压缩骨折行椎体成形患者134例,其中出现骨水泥椎旁血管渗漏患者共23例设为实验组,取未出现骨水泥椎旁血管渗漏且有完整影像学资料43例患者设为对照组。通过椎体成形前后行脊柱和胸部X射线检查确定两组患者是否存在骨水泥椎旁血管渗漏及骨水泥性肺栓塞。结果与结论:134例患者中共有23例出现骨水泥椎旁血管渗漏,占17.2%。出现椎旁血管渗漏的23例中有3例出现骨水泥性肺栓塞,占出现椎旁血管渗漏患者的13%,但均无胸部症状。对照组43例患者中未出现椎旁血管渗漏的患者也未出现骨水泥性肺栓塞,两组比较差异有显著性意义(P=0.039)。提示骨质疏松性椎体压缩骨折患者行椎体成形过程中一旦出现骨水泥椎旁血管渗漏,尽管并无胸部症状仍应警惕骨水泥性肺栓塞可能。
BACKGROUND： Percutaneous injection of bone cement into the vertebral body can enhance the vertebral strength and vertebral stability, and obtain pain relief. But the bone cement may leakage into the paravertebral vessels during injection, and may back to the right ventricle and flow into the pulmonary artery through vena cave and thus causing pulmonary embolism.OBJECTIVE： To evaluate the relationship between cement paravertebral vascular leakage and pulmonary cement embolism during percutaneous vertebroplasty.METHODS： Totally 134 cases of osteoporotic compression fractures treated with vertebroplasty were retrospectively analyzed. Among them, 23 cases of cement paravertebral vascular leakage were considered as the experimental group, and the 43 cases without cement paravertebral vascular leakage and had the complete imaging data were considered as the control group. The spine and chest X-ray films were taken before and after vertebroplasty to detect whether there were cement paravertebral vascular leakage and pulmonary cement embolism in the patients of two groups.RESULTS AND CONCLUSION： Among the 134 patients, 23 patients had cement paravertebral vascular leakage,and accounted for 17.2%. Among the 23 patients with cement paravertebral vascular leakage, three cases had pulmonary cement embolism without chest symptoms, and accounted for 13%. No pulmonary cement embolism occurred in the 43 patients without paravertebral vascular leakage of the control group, and there was no significant difference between two groups（P=0.039）. Although the patients with cement pulmonary embolismremained asymptomatic, pulmonary cement embolism remained possible if cement paravertebral vascular leakage was detected during vertebroplasty.
