Abstract:
Objective To determine the nature of enlarged mediastinal lymph nodes,the study of CT-guided transbronchial needle aspiration biopsy(CT-TBNA) was conducted. Methods According to classification and locating standard of mediastinal lymph nodes,CT-TBNA was performed in 158 mediastinal lymph nodes of 73 patients,including 54 primary lung cancer with enlarged mediastinal lymph nodes,5 malignant lymphoma, 3 mediastinal abscess and 11 mediastinal inflammatory adenopathy. Results CT confirmed that the needles were inside all 158 lymph nodes. Adequate aspirates for histologic and/or cytologic diagnosis were obtained in 136 of 158 (86%) lymph node biopsies. No serious complications occurred. Conclusion Locating standard of CT-guided TBNA was reliable. Puncture was safe and cost-effective.CT-TBNA was important for ascertaining the nature of mediastinal adenopathy and staging of neoplasms.
