CT引导下经同轴套管穿刺活检同步MWA治疗用于高度可疑恶性肺结节患者的疗效评价

CT-Guided Coaxial Cannula Biopsy Combined with MWA Treatment was Evaluated in Patients with Highly Suspected Malignant pulmonary nodules

目的分析CT引导下经同轴套管穿刺活检同步微波消融(MWA)治疗用于高度可疑恶性肺结节患者的临床疗效。方法回顾2020年1月至2022年2月期间在医院诊治的80例89个高度可疑肺结节患者,其中38例(43个肺结节)患者在CT引导下经同轴套管穿刺活检后同步MWA治疗(同步组),另42例(45个肺结节)患者在穿刺活检证实为恶性结节后再行MWA治疗(序贯组);对比两组手术情况。结果两组患者手术操作成功、完全消融率、消融有效率均为100%。同步组术后气胸、胸腔积液、咯血较序贯组减少,术后3 d患者的FVC、FVE1、PEF均高于序贯组(P<0.05)。结论CT引导下经同轴套管穿刺活检同步MWA治疗高度可疑恶性肺结节,使并发症发生率降低,安全性高。

Objective To analyze the clinical efficacy of CT-guided coaxial cannula biopsy with simultaneous microwave ablation(MWA)in patients with highly suspected malignant pulmonary nodules.Methods A review was made of 80 patients with 89 highly suspicious pulmonary nodules in hospital from January 2020 to February 2022,of which 38 patients(43 pulmonary nodules)were treated with MWA after coaxial cannula biopsy under CT guidance(synchronous group),and 42 patients(45 pulmonary nodules)were treated with MWA after the biopsy confirmed to be malignant nodules(sequential group).The two groups of surgeries were compared.Results The successful operation,complete ablation rate and ablation rate of ablation were 100%in both groups.The postoperative pneumothorax,pleural effusion,and hemoptysis in the synchronous group were reduced compared with those in the sequential group,and the FVC,FVE1 and PEF were higher than those in the sequential group(P<0.05)in the synchronous group.Conclusion CT-guided coaxial cannula biopsy combined with MWA in the treatment of highly suspected malignant lung nodules reduces the complication rate and has high safety.
