目的探讨CT导引下经皮穿刺针吸活检对肺部病变的临床应用价值。资料与方法回顾性分析3652例肺部病变CT导向下经皮针刺切割活检术及病理组织学检查。结果经手术、随访或临床检查证实为恶性肿瘤者2236例,良性病变者共1416例,其中穿刺病理证实为恶性肿瘤2148例,确诊率为96.1%;假阴性88例,假阴性率为3.9%;无假阳性。穿刺诊断良性病变者1140例,确诊率为80.5%。穿刺并发症发生率较低,发生气胸150例,发生率为4.1%。结论CT引导下经皮穿刺针吸活检术对肺部病变的诊断安全、有效,准确性高,并发症少,具有临床应用价值。
Objective To investigate the clinical value of CT guided percutaneous needle aspiration biopsy on pulmonary lesions. Materials and Methods CT-guided percutaneous needle biopsy and histopathological examination of 3652 cases of pulmonary lesions were retrospectively analyzed. Results Totally 2236 cases were confirmed as malignant tumors by operation, follow-up or clinical examination. There were 1416 benign lesions, of which 2148 were malignant tumors by puncture. The diagnosis rate was 96.1%. The false negative rate was 88 and the false-negative rate was 3.9% No false positives. Puncture diagnosis of benign lesions in 1140 cases, the diagnosis rate was 80.5%. The incidence of puncture complications is low, pneumothorax occurred in 150 cases, the incidence was 4.1%. Conclusion CT-guided percutaneous needle aspiration biopsy is safe, effective, accurate, and has few complications. It is of clinical value.
