摘　　要：目的:探讨CT引导下20G切割式穿刺活检针在胸部病变活检中的临床应用价值,并分析并发症情况。材料和方法:回顾性分析资料完整的72例CT引导下胸部穿刺活检病例,所用的活检器材均为20G切割式穿刺活检针。纵隔病变5例,胸膜病变5例,肺部病变62例。统计穿刺活检诊断准确性,恶性病变诊断敏感性、特异性,分析并发症及其影响因素。结果:穿刺活检病理诊断为恶性病变58例,良性病变8例,非特异性诊断6例,后均经手术切除、临床治疗或随访证实。穿刺活检诊断准确率95.8%(66/72),恶性病变诊断敏感性95.1%(58/61),特异性为100%(11/11),无假阳性病例。6例(8.3%)发生并发症:气胸4例,肺泡出血1例,少量咯血1例。结论:采用20G切割式穿刺活检针进行CT引导下经皮胸部穿刺活检准确率高、并发症少,具有较高的临床价值。Purpose：To evaluate the diagnostic value and complications of CT-guided biopsy of thoracic lesions using 20-gauge（20G） cutting needle.Materials and Methods：We retrospectively analyze the diagnostic outcome of 72 cases of CT-guided biopsy of thoracic lesions using 20G coaxial cutting needles：5 cases with mediastinal lesions,5 cases with plural lesions,other 62 cases with pulmonary lesions.Sensitivity,specificity,and diagnostic accuracy were calculated,complications and the relative factors were evaluated.Results：Biopsy diagnosis：58 cases were malignant,8 cases were benign,6 cases were non-specific.All cases were finally proved by surgical operation and clinical follow-up.The diagnostic accuracy was 95.8%（66/72）.The diagnostic sensitivity of malignant lesions was 95.1%（58/61）,specificity was 100%（11/11）,no false-positive result was found.6 cases（8.3%） had complications.Pneumothorax occurred in 4 cases（5.5%）,pulmonary alveolar hemorrhage occurred in 1 cases（1.4%）,hemoptysis occurred in 1 cases（1.4%）.Conclusions：CT-guided biopsy using 20G cutting needles is a useful technique for the diagnosis of thoracic lesion with high accuracy and low complications.
