CT导引下纵隔穿刺活检术的临床应用及价值

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 25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％（25／26）,细胞学准确率为95．8％（23／24）,组织学准确率87．5％（21／24）,总体诊断准确率为92．0％（23／25）。气胸发生率为24．0％（6／25）,最多肺压缩15例,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,安全的检查手段。

Clinical application and value of CT-guided mediastinal needle biopsy in mediastinal lesions

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.
