目的:探讨CT引导下经皮穿刺活检诊断肺上沟癌。方法:采用自行研制9号螺旋穿刺针,选择最佳层面,确定进针点,提取组织标本。结果:从1996年6月至2004年3月,我院在CT引导下经皮肺穿刺活检诊断肺癌628例,确诊Pancoast瘤24例。鳞癌10例,腺癌9例,小细胞癌和大细胞癌各2例,腺鳞癌1例,胸腺瘤1例,淋巴瘤1例,畸胎瘤1例,结核和支气管囊肿各2例,3例假阴性,无假阳性结果。并发症:1例术后出现少量气胸,无需特殊处理。3例有少量咯血。结论:CT有良好的分辨率,CT导向胸部病灶经皮肺穿刺活检对恶性肿瘤诊断敏感性达90%～100%(本例的确诊率为91.17%),特异性高,能对病变提供病理诊断。对Pancoast瘤早期确诊具有极其重要的意义。
Objective: To investigate the diagnosis of suprachorospinal carcinoma by percutaneous needle biopsy under CT guidance. Methods: Self-developed No. 9 spiral puncture needle was used to select the best level, determine the point of entry, and extract tissue specimens. RESULTS: From June 1996 to March 2004, CT-guided percutaneous lung biopsy underwent CT-guided diagnosis of 628 lung cancers and 24 confirmed Pancoastomas. 10 cases of squamous cell carcinoma, 9 cases of adenocarcinoma, 2 cases of small cell and large cell carcinoma, 1 case of adenosquamous carcinoma, 1 case of thymoma, 1 case of lymphoma, 1 case of teratoma, 2 cases of tuberculosis and bronchial cyst , 3 false negatives, no false positive results. Complications: A small amount of pneumothorax occurred after surgery and no special treatment was required. 3 cases had a small amount of hemoptysis. Conclusion: CT has good resolution, CT-guided percutaneous transthoracic needle biopsy of breast lesions for the diagnosis of malignant tumor sensitivity of 90% to 100% (in this case the diagnosis rate was 91.17%), high specificity, can provide pathological changes diagnosis. It is of great significance to early diagnosis of Pancoastoma.
