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。
Objective: To investigate the clinical value of CT guided 20G biopsy needle biopsy in thoracic lesions and to analyze the complications. Materials and Methods: A retrospective analysis of 72 cases of CT-guided chest biopsy under the guidance of the biopsy equipment used are 20G biopsy needle. 5 cases of mediastinal lesions, 5 cases of pleural disease, pulmonary lesions in 62 cases. Statistics puncture biopsy diagnostic accuracy, sensitivity, specificity of malignant lesions, analysis of complications and its influencing factors. Results: The pathological diagnosis of biopsy in 58 cases of malignant lesions, benign lesions in 8 cases, non-specific diagnosis in 6 cases, after surgery, clinical treatment or follow-up confirmed. The diagnostic accuracy of biopsy was 95.8% (66/72), the sensitivity of malignant lesions was 95.1% (58/61) and the specificity was 100% (11/11). There was no false positive case. Complications occurred in 6 cases (8.3%): pneumothorax in 4 cases, alveolar hemorrhage in 1 case, and a small amount of hemoptysis in 1 case. Conclusion: The diagnostic accuracy of percutaneous thoracentesis and biopsy with 20G biopsy needle guided by CT is high, and there are few complications. It has high clinical value.
