目的：探讨 Ｃ Ｔ引导下使用切割针行经皮纵隔肿块穿刺活检术的临床价值。材料和方法：对 ３２例纵隔肿块，使用１６－１９Ｇ切割针在ＣＴ引导下施行穿刺活检术，分别进行细胞学和组织学检查。结果：诊断准确性为９３．８％，假阴性率６．１％。并发症包括气胸（３例）、肺内出血临（５例）、纵隔内出血（３例），其发生与穿刺路径有关；总体发生率为３４．４％（１１／３２），均无需特殊处理。结论：ＣＴ引导下经皮纵隔肿块切割活检术诊断准确性高，相对安全，值得推荐选择性应用。
Objective: To investigate the clinical value of C T-guided needle biopsy of percutaneous mediastinal puncture. Materials and Methods: Thirty-two mediastinum masses were examined by CT-guided 16-19G needle biopsy. Cytology and histology were performed respectively. Results: The diagnostic accuracy was 93.8% and the false negative rate was 6.1%. The complications included pneumothorax (3 cases), intrapulmonary bleeding (5 cases) and mediastinal hemorrhage (3 cases), which were related to the puncture path. The overall incidence was 34.4% (11/32) without any special treatment. CONCLUSION: CT-guided percutaneous mediastinal mass biopsy has high diagnostic accuracy and relatively safety. It is worth recommending selective application.
