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101例,病灶用意大利或美国20 G活检针至少穿刺取材。结果:肺结节穿刺准确率达100%,病理证实恶性病灶73例、良性病灶28例,其中结节太小取材少不能定性1例。诊断准确率为99.01%,并发症中气胸发生率13.86%、咯血17.82%,无严重并发症,穿刺针通过肺大泡而没有引起气胸1例。结论:CT引导经皮穿刺直径≤3 cm肺部结节活检的准确性高而并发症较低,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。
Odjective： To evaluate multi - slies spiral CT - guided pereutaneous cutting-needle biopsy in pulmonary nodules less than 3em in diameter.Method： There were 101 pulmonary lesions less than 3em in diameter under CT- guided pereutaneous needle biopsy, Every pulmonary nodule was punctured more than twice with 20 Guage needles made in Italy or U.S.A. Results： The accuracy of punctured through pulmonary nodules was 100 %.There were 73 pulmonary mahgnant tumors and 28 bengin nodules identified by pathological histology and only one without pathological result for small in size in this group.Diagnostic accuracy were 99.01% .The complication included slightly pneumothorax 13.86 %, and hemoptosis in 17.82 % without severe complication. Conclusion： CT- guided pereutaneous needle biopsy in solitary pulmonary nodules ≤3 cm in diameter is best method with high accuracy and low complication for pathological diagnosis before clinic treatment.
