CT导引细针吸取细胞学检查诊断肺周及胸膜病变

Cytologic Examination and Diagnosis of Peri-pulmonary and Pleural Lesions by CT-Guided Fine-needle Aspiration

目的：对影像学检查所发现的肺周、纵隔及胸膜病变进行在ＣＴ导引下的细胞学检查，以期获得对该部位病变定性诊断和分类的经验。材料和方法：采用ＣＴ（ＳＣＴ－２０００Ｔ－１１型，日本岛津）对２２例患者的肺周、纵隔及胸膜病变扫描定位，７号腰椎穿刺针穿刺取材涂片，Ｐａｐ染色和光镜观察。结果：２２例中除１例因患者配合不佳而致针吸失败外，２１例获得准确和基本准确诊断，由于采用了细针，还减少或避免了出血、气胸等并发症。结论：肺周及胸膜病变的ＣＴ导引细针吸取细胞学检查是一种有效、简便和准确性高的诊断方法。

Purpose:We performed CT guide cytologic examination of peri-pulmonary, mediastinal and pleural lesions discovered by imaging examination. Materials and Methods: CT (SCT-2000T-11 Model, Shimadzu, Japan) was applied in 22 cases for the scanning localization of peri-pulmonary, mediastinal and pleural lesions, smears were obtained by No. 7 lumbar needle and observed by Pap staining and microscope. Results:Accurate or basically accurate diagnosis was obtained in 21 cases, except one which was due to unfavourable cooperation, resulting in failure of needle suction. Because of fine needles application, complications of bleeding and pneumothorax were reduced or avoided. Conclusion: This kind of cytologic exasmination is a sort of diaguostic method which is ont only effective, but also simple and with high accuracy.
