【摘要】 目的：探讨同轴穿刺针在胸部病变活检中的应用。材料与方法：应用仿Ｇｒｅｅｎｅ针改制的２０Ｇ同轴穿刺针对４８例胸部病变患者在ＣＴ导向下穿刺活检。其中３８例结节或肿块性病变大小为１．５～４．２ｃｍ×２．８～１０．５ｃｍ，平均２．６ｃｍ×５．８ｃｍ；肺实变１０例。结果：４８个病灶共取材１１０次，平均２．３次。组织学标本获取率９３．８％（４５／４８），恶性病变诊断准确率１００％（２１／２１），良性病变诊断准确率９２．６％（２５／２７），总的准确率９５．８％（４６／４８）。肺内病变穿刺后出现局限性气胸和少量咯血各２例。结论：该穿刺针在胸部病变的穿刺中能获取足够的标本供细胞学和组织学分析，且并发症少。更多还原

【Abstract】 Objective: To evaluate the coaxial cutting needle in the performing of percutaneous thoracic biopsy (PTB).Materials and Methods:CT guided PTB with a 20 gauge coaxial cutting needle, a modified Greene needle, was performed in 48 patients. Lesions were located in thorax (n=14), lung (n=30) or mediastinum (n=14).Results:Total 110 cuttings were performed on 48 lesions. Histological specimens were obtained in 45 cases (95.8%). The diagnostic accuracy was 100% for malignant lesions (21/21), 92.6% for benign lesions (25/27), with a total accuracy of 95.8%. Localized pneumothorax and slight hemoptysis were seen in two patients each.Conclusion: The modified coaxial cutting needle can get adequate tissue sample for histological exam with few complications.更多还原
