CT引导下经皮肺穿刺活检术的临床应用

Clinical Application of CT-guided Percutaneous Fine-needle Aspiration Biopsy of Lung

目的评价CT引导下经皮肺穿刺活检术在肺内占位性病变诊断中的价值。方法选取45例经影像检查确定为肺部占位性病变的患者,采用CT引导下经皮穿刺切割或抽吸取得标本进行病理学检查。结果穿刺成功率100%,其中43例获得准确诊断,诊断准确率为95.6%;其中恶性肿瘤21例(鳞癌7例、腺癌5例、肺泡癌1例、转移癌8例),良性病变22例(结核19例、炎性假瘤2例、错构瘤1例)。并发症发生率6.7%,包括少量气胸2例,轻微咯血1例,均不需特殊处理。结论 CT引导下经皮肺穿刺活检术操作简便、安全,诊断准确性高、并发症少,可作为肺内结节病变的常规诊断手段。

Objective To evaluate the clinical value of CT-guided percutaneous fine-needle aspiration biopsy of lung. Methods CT-guided percutaneous fine-needle aspiration biopsy of lung was performed in 45 cases with pulmonary diseases. Results Effective specimens were obtained from the 45 cases （achievement ratio 100%）. Final diagnosis was made in 43 cases （diagnostic accuracy 96.6%）. 21 cases were confirmed to be malignant, 22 cases benign, including 7 cases of squamous-celled carcinoma, 5 cases of adenocarcinoma, 1 cases of alveolar carcinoma, 8 cases of metastatic carcinoma, 19cases of tuberculosis,2 cases of inflammatory pseudotumors, 1 case of hamartoma. The major complications included 2 cases of small pneumothorax and 1 case of little hemoptysis （incidence rate 6.7%）. Conclusion CT-guided percutaneous fine-needle aspiration biopsy of lung is a feasible and safe method in diagnosis of pulmonary lesions with high accuracy and few complication, and can be the routine method in diagnosis of pulmonary lesions.
