CT引导下经皮肺穿刺活检在肺部占位病变中的诊断价值

The diagnostic value of percutaneous CT-guided needle lung biopsy in pulmonary occupying lesions

目的探讨CT引导下经皮肺穿刺活检对肺部占位病变的诊断价值。方法CT扫描确定最佳的穿刺点、局麻后CT引导下组织切割针经皮刺入到病灶,切割组织行病理检查。结果56例肺占位病变行CT引导下经皮肺穿刺活检,53例得到确诊,阳性率为94.6%。并发症包括少量气胸11例,肺出血9例,少量咯血5例,均不需特殊处理。结论CT引导下经皮肺穿刺活检对肺占位病变的诊断阳性率高、并发症轻,值得临床推广。

Objective To investigate diagnostic value and safety of percutaneous CT-guided needle lung biopsy in pulmonary occupying lesions. Methods Fifty-six patients underwent chest CT before percutaneous needle biopsy to measure the size and depth of the lesion and to accurately localize it. Results The diagnosis was confirmed by needle biopsy in 53 patients （94.6%）. The complications included mild pneumothorax （ n = 11 ） , poulmonary bleeding （ n = 9 ） and small hemoptysis （ n = 5 ）. All complications didn＇t represent the need for medical specific treatment. Conclusion Percutaneous CT-guided needle biopsy is a safe and effective means in the diagnosis of pulmonary occupying lesions.
