CT引导下同轴活检系统对肺部占位病变诊断的临床意义

Application of Biopsy Gun Combined with Trocar of Biopsy in the Percutaneous Lung Biopsy for Pulmonary Diseases Under CT-Guilded

目的:评价CT引导下同轴活检系统对肺部占位病变诊断的临床意义。方法:统计68例行CT引导下同轴定位针联合活检枪经皮肺穿刺活检结果,结合文献探讨CT引导下同轴活检系统对肺部占位病变诊断的临床意义。结果:68例患者100%取得病理标本,其中结核24例(35.3%),恶性肿瘤40例(58.8%),炎性假瘤4例(5.9%);并发症少(5.9%),2例出现少量气胸,2例出现少许痰中带血。结论:CT引导下同轴套管针联合活检枪经皮肺穿刺活检对肺部疾病诊断率高,具有重要的临床价值,安全可行,值得临床应用。

Objective： To investigate the clinical application of biopsy gun combined with trocar of biopsy in the percutaneous lung biopsy for pulmonary diseases under CT-guidance.Methods： CT guided percutaneous lung biopsy,by biopsy gun combined with trocar,were performed on 68 patients who suffered from pulmonary lesions.The diagnosis values and complications were retrospectively analyzed,and the related literatures were reviewed.Results： The successful rate of puncture diagnosis was 100%.Forty cases of lung cancer patients was diagnosed,besides,24 cases were diagnosed as pulmonary tuberculosis and 4 cases were diagnosed as inflammatory pseudotumor.The incidence of postoperative complications was 5.9%（2 pneumothorax,2 blood sputum）,which were relieved without treatment.Conclusion： CT guided percutaneous lung biopsy by biopsy gun combined with trocar of biopsy is relatively safe and reliable method of diagnosing pulmonary lesions.
