摘　　要：目的观察CT引导下经皮肺穿刺活检诊断的临床效果和并发症原因分析。方法收集行CT引导下经皮穿刺肺活检95例患者的临床资料,分析患者行CT引导经皮肺穿刺活检的诊断准确率与各种并发症。结果 95例患者中诊断恶性肺部病变72例（75.8%）,准确率98.5%;良性病变23例（24.2%）,准确率91.3%。穿刺平均皮损面积21.4mm2（范围8mm2~78mm2）,恶、良性患者并发血胸与气胸分别为5.6%、21.7%。Pearson卡方检验显示,经肺损伤深度与肿瘤大小成负相关;良性肺病变患者的穿刺并发症发生率明显高于恶性病变组（χ2=8.13,P=0.015）。结论CT引导下经皮穿刺肺活检术辅助诊断肺部恶性疾病准确率较高,然而在辅助肺部良性病变的诊断中因并发症较高应慎重应用。Objective To explore diagnostic efficiency of CT-guided percutaneous puncturations for lung biopsies.Methods Clinical data of 95 patients underwent CT-guided lung biopsies were involved in the present study.There were31 females and 64 males,aged from 13 to 78years old,and the mean age was 59 years old.All the patients underwent CT-guided percutaneous puncturations for lung biopsies,and analyzed the diagnostic accuracies and complications.Results The biopsy samples for malignant and benign lesions were adequate in 75.8% and 24.2%,with the diagnostic accuracy of 93.2% and 95.5%,respectively.The mean lesion size was 21.4mm2（range,8to 78mm2）.The pneumothorax and haemoptysis occurred in 5.6% and 21.7% of malignant and benign lung lesions of patients,respectively.The results showed that it was significant higher of the incidence of complications in patients with benign lesions than the of malignant lesions in lung（χ2=8.13,P=0.015）.The traversed lung-length was negatively correlated with the tumor size of lung.Conclusion The diagnostic efficiency of CT-guided percutaneous puncturations for lung biopsies is adequate for malignant lesions;however,more prudences must be paid when it is applying for the benign lesions.
