摘　　要：目的探讨CT引导下微波消融(MWA)联合经皮椎体成形术(PVP)治疗脊柱转移瘤的近期疗效并分析术后发生骨水泥渗漏的危险因素。方法回顾性分析2020年1月至2023年6月山东第一医科大学附属中心医院应用CT引导下MWA联合PVP治疗脊柱转移瘤50例74节椎体,采用疼痛数字评定量表评分(NRS)、吗啡日消耗量(DMC)和日常生活能力量表评分(ADL)评价近期临床疗效,术后CT定期复查评价局部肿瘤控制及骨水泥渗漏情况。纳入性别、年龄、脊柱转移瘤的最大径、转移瘤类型、原发癌Tomita分类、受累椎体水平、骨水泥注射量、注射侧向、病理性骨折和椎体后壁破裂等,采用单因素和多因素二元logistic分析评估术后发生骨水泥渗漏的危险因素。结果术前、术后1天、1周和1、3、6个月随访NRS分别为(7.24±1.41)、(4.76±1.45)、(3.42±1.34)、(2.86±0.90)、(2.20±0.57)、(1.66±0.72)分;术前、术后1天、1周和1、3、6个月随访DMC分别为(110.40±94.61)、(66.10±51.23)、(47.30±37.49)、(32.90±22.84)、(25.60±18.97)、(15.36±13.43)mg;术前、术后1周和1、3、6个月ADL分别为(40.80±11.45)、(53.20±6.68)、(60.40±5.14)、(62.90±4.75)、(64.80±4.51)分。术前及术后6个月内随访NRS、DMC、ADL的差异有统计学意义(P<0.05)。术后6个月影像检查随访,有46例患者肿瘤得到控制,局部肿瘤复发率为8%(4/50)。在74节椎体中有17(22.97%)节椎体发生轻度骨水泥渗漏。多因素logistic分析显示病理性骨折(OR=9.581,95%CI=2.292~40.055,P=0.002)及椎体后壁破裂(OR=5.105,95%CI=1.041~25.022,P=0.044)是骨水泥渗漏的独立危险因素,病理性骨折(OR=35.333,95%CI=4.029~309.840,P=0.001)是皮质骨水泥渗漏的独立危险因素,未发现血管骨水泥渗漏的独立危险因素,椎体后壁破裂(OR=48.400,95%CI=4.725~495.753,P=0.001)是椎管内骨水泥渗漏的独立危险因素。结论MWA联合PVP治疗脊柱转移瘤能快速缓解患者疼痛,提高日常活动能�Objective To investigate the short-term efficacy of CT-guided microwave ablation(MWA)combined with percutaneous vertebroplasty(PVP)for spinal metastases,and to analyze the risk factors for postoperative cement leakage.Methods The clinical data of 50 patients with spinal metastases(74 diseased vertebrae in total),who were treated with CT-guided MWA combined with PVP at the authors′hospital from January 2020 to June 2023,were retrospectively analyzed.Numerical Pain Rating Scale(NRS),daily morphine consumption(DMC)and Activity of Daily Living Scale(ADL)were used to evaluate the short-term efficacy.Regular postoperative CT reexamination was carried out to assess the condition of local tumor control and bone cement leakage.Univariate analysis and multivariate binary logistic analysis of gender,age,maximum diameter of metastatic lesion,type of metastasis,Tomita classification of primary tumor,level of affected vertebrae,injected volume of bone cement,injection side,pathological fracture,and posterior vertebral wall rupture were performed to determine the risk factors for postoperative occurrence of bone cement leakage.Results The preoperative,and the postoperative one-day,one-week,one-month,3-month and 6-month NRS were(7.24±1.41),(4.76±1.45),(3.42±1.34),(2.86±0.90),(2.20±0.57),(1.66±0.72)points respectively.The preoperative,and the postoperative one-day,one-week,one-month,3-month and 6-month DMC were(110.40±94.61),(66.10±51.23),(47.30±37.49),(32.90±22.84),(25.60±18.97),(15.36±13.43)mg respectively.The preoperative,and the postoperative one-week,one-month,3-month and 6-month ADL were(40.80±11.45),(53.20±6.68),(60.40±5.14),(62.90±4.75),(64.80±4.51)points respectively.The differences in NRS,DMC,ADL between their preoperative values and postoperative 6-month values were statistically significant(all P<0.05).Postoperative 6-month imaging follow-up check revealed that tumor was controlled in 46 patients and the tumor recurrence rate was 8%(4/50),and mild bone cement leakage occurred in 17 of 74 vertebrae(2
