CT引导经皮肺穿刺的临床应用--附80例临床分析

目的探讨CT引导下经皮细针肺穿刺吸取标本的方法及对肺部结节病变的诊断价值.方法总结分析80例肺部结节病变患者,全部CT检查高度怀疑肺部恶性肿瘤,42例纤维支气管镜检查,无阳性发现.术前CT定位,确定穿刺深度、方向和角度,选择0.7～0.9 mm 穿刺针吸取标本,细胞学检查.结果细胞学标本获取76例,获取率为95%.其中肺癌68例,结核6例,炎症2例.并发局限性气胸6例.结论CT引导下经皮细针肺穿刺对肺部结节性病灶,细胞学标本获取率高,操作简单、安全、可靠.

Clinical Application of Lung Puncturing Through Skin Under the Guidance of CT Scan

Objective To explore the method of lung puncturing through skin to absorb samples under the guidance of CT scan and its diagnostic value on the lung nodes.Methods Eighty patients with lung nodes were selected.All of them were highly suspected to be malignant tumors.Forty two patients were examined by the bronchoscope and the results were negative.The position was fixed and the depth,direction and angle were determined before puncturing,then the acupuncture needles whose diameters varied from 0 7 mm-0 9 mm were used to absorb the samples and they were examined with cytology techniques.Results The number of acquainting the samples was 76,and the rate of acquiantance was 95%.Among them 68 cases were lung cancers,6 cases were TB,the else were inflammations.There were 6 cases complicated limit pneumothorax.They were recovered by no special treatment.Conclusions The operation of puncturing the lungs node through the skin under the guidance of CT scan is easy,safe and reliable and the successful rate is high.
