摘　　要：[目的 ]探讨CT导引下纵隔穿刺活检术的临床应用及价值。 [方法 ]2 5例纵隔疾病患者 ,在CT导引下应用自动切割式活检针取材。所有病例均同时行组织学和细胞学检查。 [结果 ]穿刺取材成功率 (刺中率 )为 96 .2 % (2 5 /2 6 ) ,细胞学准确率为 95 .8% (2 3/2 4 ) ,组织学准确率 87.5 % (2 1/2 4 ) ,总体诊断准确率为 92 .0 % (2 3/2 5 )。气胸发生率为 2 4 .0 % (6 /2 5 ) ,最多肺压缩 15 % ,肺出血 3例 (12 % ) ,咯血 1例 (4 % ) ,随诊。结论 :CT导引下纵隔穿刺活检术是一种有效。To explore the clinical value of mediastinal needle biopsy under CT guidance. CT-guided percutaneous biopsy were performed in 25 mediastinal lesions with automated cutting needle. Bioptic samples were examined in histology and cytology simultaneously. The accuracy of puncture was 96% (24/25); diagnostic accuracy was 95.8% (23/24) in cytologic study and 87% in histologic examination. The overall diagnostic accuracy was 92% (23/25). The incidence of pneumothorax was 24% (6/25), no one was needed to treat with drainage. 3 cases were observed lung hemorrhage ; hemoptysis occurred in only one (4%) of the patients, follow-up was needed. [Conclusion] Mediastinal needle biopsy under CT guidance is a safe and effective procedure towards the diagnosis of mediastinal masses.
