摘要
【目的】探讨应用软组织切割针在CT导引下纵隔肿块性病变穿刺活检技术临床的应用价值。【方法ICT导引下应用18G和20G软组织切割针对77例纵隔肿块性病变在进行穿刺活检，比较穿刺活检与病理符合率。【结果】纵隔肿块穿刺技术成功率100％。病理明确诊断67例（87．0％），不能明确诊断10例；18G针活检35例、20G针活检42例，阳性率分别为91．4％、83．3％；〈3cm病灶16例，3．1～5．0cm病灶32例，〉5．1cm病灶29例，活检阳性率分别为81．3％、87．5％、89．7％；胸腺类肿瘤、转移性肿瘤、淋巴唐、神经源性肿瘤活检阳性率分别为91．3％、93．3％、88．2％、60％。穿刺并发症发生率为13％。【结论]CT导引下经皮穿刺活检对纵隔肿块性病变是一种安全有效的诊断方法，值得临床推广应用。
[Objective] To explore the clinical value of CT-guided biopsy with cutting needle of soft tissue in mediastinum mass lesion. [Methods]CT-guided biopsy with 18G and 20G cutting needle of soft tissue was performed for 77 cases of mediastinum mass lesion. The coincidence between puncture biopsy and pathological examination was compared. [Results]The successful rate of biopsy technology of mediastinum mass was 100%. There was 67 cases（87.0%） with definite pathological diagnosis and 10 cases without definite diagnosis. The 18G needle biopsy was performed in 35 cases and the 20G needle biopsy was performed in 42 cases, and their positive rate was 91.4% and 83.3%, respectively. The lesion size of 16 cases was less than 3cm, and that of 32 cases was 3.1-5.0cm, and that of 29 cases was more than 5. lcm, and their positive rate of the biopsy was 81.3%, 87.5% and 89.7%, respectively. The positive rate of the biopsy in thymus tumor, metastatic tumor, lymphoma and neurogenic tumor was 91.3%, 93.3%, 88.2% and 60%, respectively. The incidence of puncture complications was 13%. [Conclusion]CT-guided percutaneous biopsy for mediastinum mass lesion is a safe and effective diagnostic method, so it is worthy of clinical application.
