改良的CT引导下同轴法经皮肺穿刺活检术应用

目的：探讨CT引导下同轴法经皮肺穿刺活检术的临床应用价值。方法：选择因肺内病变需活检的116例患者，所有患者均采用CT引导下自动活检枪同轴法经皮肺穿刺活检术。结果：116例患者均成功获取病理标本，穿刺成功率100％，病变阳性率94．8％，并发症6例（5．2％），经对症处理后2～7天后患者身体逐渐恢复。结论：改良CT引导下经皮肺穿刺活检术器材简单易得，费用低廉操作简便，穿刺成功率高、并发症发生率低。

A modified CT-guided percutaneous lung biopsy method

Objective：To investigate the clinical value of a modified CT-guided coaxial percutaneous lung biopsy method. Methods： 116 patients with lung lesions who require biopsy were enrolled from January 2007 to January 2012, They all un-derwent coaxial cutting needle biopsy,using the automatic biopsy （needle） gun joint disposable thoracentesis package. Re-suits：Pathological specimens were all successfully obtained in 116 subjects. The puncture success rate was 100%, biopsy positive rate was 94.8%. There were six cases with complications （5.2%） ,The patients gradually recovered after 2 to 7 days treatment. Conclusion：Modified CT-guided percutaneous lung biopsy equipment is simple and easy to get, puncture suc-cess rate is high,complication rate is low. It is cheap and easy to operate is suitable.
