CT引导下经皮肺穿刺活检的应用价值及其并发症

目的：探讨CT引导下经皮肺穿刺活检的应用价值及并发症。方法：回顾性分析CT引导肺部病变穿刺活检的213例资料，并统计穿刺成功病例的细胞学、病理学结果及并发症。结果：213例中确定病理诊断的有207例，其中腺癌78例、鳞癌53例（其中低分化鳞癌12例）、透明细胞癌3例、查到癌细胞但未能分型14例、小细胞癌22例、复合细胞癌2例、纤维组织3例、结节病3例、肺结核6例和炎性假瘤23例；穿刺失败和因取材过少或误取而未明确诊断的有6例。发生气胸7例，少量咯血2例，血胸1例。穿刺活检总确诊率为97％。结论：CT引导下经皮肺穿刺活检是一种定位准确、安全可靠、阳性诊断率高的检测方法，少数患者出现并发症。

Value of CT-guided percutaneous lung biopsy and its complications

Objective：To investigate the value and complication of CT-guided percutaneous lung biopsy. Meth-ods：Retrospective analysis of CT guided biopsy of lung lesions for 213 cases were performed. Results：Of 213 cases i-dentified diagnosis in 207 cases,of which 78 cases were adenocarcinoma,53 squamous cell carcinoma（ one of 12 cases of poorly differentiated squamous cell carcinoma）,three cases clear cell carcinoma,found in cancer cells but failed to type in 14 cases,small cell cancer 22 cases,2 cases complex cell carcinoma,3 cases fibrous tissue,3 cases sarcoido-sis,tuberculosis,and 6 cases inflammatory pseudotumor of the 23 cases;puncture due to material failure and too little access or misuse in 6 cases without a clear diagnosis. 7 cases happened pneumothorax,2 cases with a small amount of hemoptysis,hemothorax 1. The total rate of needle biopsy confirmed 97%. Conclusion：CT-guided percutaneous lung biopsy is an accurate,safe,reliable,with high diagnosis rate detection method,a small number of patients happen com-plications.
