CT引导下经皮肺穿刺活检在诊断不明肺部肿块中的应用

目的:探讨CT引导下经皮肺穿刺活检在诊断不明肺部肿块的临床应用价值.方法:CT引导下,经皮肺穿刺活检术取得组织标本,进行组织病理学诊断,分析该方法诊断肺部肿块的准确性及并发症的发生率.结果:126例患者中123例(97.6％)获得活体组织标本,病理组织学明确诊断为恶性病变111例(阳性率90.2％):3例未能确诊:18例(14.3％)出现并发症,其中3例较为严重并需要处理.结论:CT引导下经皮肺穿刺活检是一种有效、微创和较为安全的检查方法.

Application of CT guided percutaneous lung biopsy in the diagnosis of unexplained pulmonary mass

Objective: To explore the clinical application value of CT guided percutaneous lung biopsy in the diagnosis of unexplained pulmonary mass.Methods: To obtain tissue specimens by CT guided percutaneous lung puncture biopsy,make histopathological diagnosis and analyze accuracy of the method in the diagnosis of pulmonary mass and complication rate.Results: 123 biopsy specimens were obtained from 126 patients(97.6%),111 cases were diagnosed as malignant lesions(positive rate 90.2%) by histopathological diagnosis;3 cases failed to confirm the diagnosis;18 cases(14.3%) had complications,including 3 cases which were serious and needed treatment.Conclusion: CT guided percutaneous lung biopsy is an effective,minimally invasive and safer inspection method.
