摘　　要：目的评价多排螺旋CT引导下经皮肺切割针活检直径≤3 cm肺结节的价值。方法CT引导下经皮肺穿刺活检肺部病灶直径≤3 cm结节81例,用意大利或美国20 G活检针对病灶至少穿刺取材2次。结果肺结节穿刺准确率达100%,病理证实恶性病灶56例,良性病灶24例;其中结节太小取材少不能定性1例,诊断准确率为98.76%。并发症中发生气胸12例(14.81%)、咯血15例(18.52%),穿刺针通过肺大泡而没有引起气胸1例,无严重并发症发生。结论CT引导经皮穿刺直径≤3 cm肺部结节活检的准确性高且发生并发症较低,可作为肺内3 cm以下孤立性结节灶在临床治疗前病理诊断的首选方法。Objective To evaluate multi-slices spiral CT-guided percutaneous cutting needle biopsy in pulmonary nodules less than 3 cm in diameter. Methods Eighty one pulmonary lesions less than 3 cm in diameter were checked by CT-guided percutaneous needle biopsy. Each pulmonary nodule was punctured more than twice with 20 Guage needles made in Italy or U. S. A. Results The accuracy of puncture through pulmonary nodules was 100 %. There were 56 pulmonary malignant tumors and 24 bengin nodules identified by pathlogical histology and only one without pathological result due to small size in this group. Diagnostic accuracy was 98. 7%. The complication included slight pneumothorax in 14.81% and hemoptosis in 18.52% without severe complication. Conclusion CT-guided percutaneous needle biopsy in solitary pulmonary nodules 43 cm in diameter is a method with high accuracy and low complication and can be the first choice for pathological diagnosis before clinic treatment.
