CT引导肺内小结节经皮穿刺活检术的临床应用

目的：评价CT引导经皮穿刺肺内直径≤1.5cm小结节的临床价值。方法：65例肺内小结节患者行CT引导经皮穿刺活检术,分析其敏感度、特异度、准确度及并发症。结果：恶性肿瘤的诊断敏感度92.3%（36/39）,阳性预测值100%;良性病变诊断特异度100%,阴性预测值89.7%（26/29）,总诊断符合率92.3%（60/65）。气胸发生率7.7%（5/65）,肺内出血发生率10.8%（7/65）,术后均未作特殊处理。结论：CT引导经皮穿刺肺内小结节直径≤1.5cm病灶准确度较高且并发症发生率较低。

Clinical Application of CT-guided Percutaneous Needle Biopsy of Small Pulmonary Nodules

Objective：To evaluate the clinical value of CT-guided percutaneous needle biopsy of small pulmonary nodules （D≤1.5cm）. Methods：65 patients with small pulmonary nodule underwent CT-guided percutaneous needle biopsy. The sensitivity, specificity, accuracy of diagnosis and complications were analyzed. Results：The sensitivity and positive prediction value for the diagnosis of malignant lesions were 92.3% （36/39） and 100% respectively. The specificity and negative pre diction value for the diagnosis of benign lesions were 100% and 89.7% （26/29） respectively. Totally the accuracy of diagnosis was 92.3% （60/65）. The incidence of complicated pneumothorax and pulmonary hemorrhage were 7.7% （5/65） and 10.8% （7/65） respectively. No specific treatment was undertaken after the biopsy procedure. Conclusion：CT-guided pereutaneous needle biopsy for the diagnosis of small pulmonary small nodules （D≤1.5cm） showed high accuracy and low incidence of complication.
