目的 评价肺结节CT导引经皮针吸活检的准确性、安全性及应用价值。方法 42例CT导引FNAB检查 ,用特制细针进行针吸活检。 42例操作 43次 ,涂片及病检。术后再作CT扫描 ,以观察并发症的发生。结果 可供细胞学涂片检查的 41例次 ,成功率 95 .3% ,可供病理学检查者 32例 ,占穿刺例次的 74.4% ,阳性结果包括肺癌 2 8例 ,肺化脓症 1例 ,淋巴瘤 1例 ,炎性假瘤 1例 ,韦革氏肉芽肿 1例。病理阳性 76 .2 % ,假阴性 4例 (包括穿刺失败 1例 ) ,不能作出病理诊断者 6例。无 1例发生气胸、血胸、肺出血或咯血。结论 特制之细针针吸活检虽其阳性检出率不及粗针 ,但其并症减低到最低的程度 ,是一个安全的创伤性检查。
Objective To evaluate the accuracy, safety and value of percutaneous needle aspiration biopsy in CT guided pulmonary nodules. Methods 42 cases of CT guided FNAB examination, needle needle biopsy with special fine needle. 42 cases operated 43 times, smears and pathological examination. Postoperative CT scan, in order to observe the occurrence of complications. Results The results of cytology smear examination in 41 cases, the success rate of 95.3%, available for pathological examination in 32 cases, accounting for 74.4% of the puncture cases, positive results include 28 cases of lung cancer, pulmonary effusion in 1 case 1 case of lymphoma, 1 case of inflammatory pseudotumor and 1 case of Wegener’s granulomatosis. Pathological positive 76.2%, false negative in 4 cases (including the failure of puncture in 1 case), can not make pathological diagnosis in 6 cases. No case of pneumothorax, hemothorax, pulmonary hemorrhage or hemoptysis. Conclusion The special fine needle aspiration biopsy, although its positive detection rate is less than the thick needle, but its complications reduced to the lowest extent, is a safe traumatic examination.
