CT引导下经皮肺活检对肺内占位病变的诊断价值

目的：探讨盯引导下经皮肺活检法对肺内占位病变的诊断价值和安全性。方法：采用CT引导下经皮肺活检法对119例肺内占位病变进行穿刺活检，分析其敏感性、确诊率、并发症及相关因素。结果：穿刺病理确诊为恶性肿瘤79例，经手术及临床观察确诊恶性肿瘤5例，良性病变共35例。灵敏度为94．0％（79／84），特异度100％（35／35），假阴性4．20％（5／119），无假阳性，总确诊率为95．8％（114／119）。术后气胸发生率16．00％（19／119），咯血发生率20．2％（24／119），血胸及脑梗死发生率均为1.70％（2／119）。结论：CT引导下经皮肺活检法相对安全、易行，确诊率高，对肺内占位病变确诊具有重要意义。

The Diagnostic Value of CT-guided Percutaneous Lung Biopsy of Lung Lesions

Objective:To evaluate the diagnostic value and the safety of CT-guided percutaneous lung biopsy of lung nodules. Methods:Datas of 119 cases lung nodules who underwent CT-guided percutaneous lung biopsy were studied. The sensitivity with diagnositic accuracy and complications were analyzed. Results:There were total 84 case of malignant tumor and 35 cases of benign lesion.79 cases of malignant tumor and 35 cases with benign lesion were diagnosed by CT-guided purcutaneous lung biopsy. 5 cases were diagnosed through clinical observation or operatioa The diagnositic sensitivity and accuracy were 94. 0%(79/84) and 100% (35/35) respectively. False negative rate and false positive rate were 4.2% and 0% respectively. The overall accurate rate was 95. 8%(114/119). Incidence of post-biopsy pneumothorax, hymoptysis, thoracic cavity bleeding and cerebral infarction were 16. 0%(19/119), 20.2%(24/119), 1.7%(2/119) and 1.7%(2/119) respectively. Conclusion: CT-guided percutaneous lung biopsy is relatively safe and has high diagnositic accuracy in lung lesions.
