CT引导下肺部穿刺活检对胸部肿块的诊断价值

Clinical Diagnosis Value of CT-guided Percutaneous Core Needle Lung Biopsy

目的:探讨CT导引下经皮穿刺切割活检对胸部肿块的诊断价值。方法:回顾性分析2003年2月-2012年2月85例胸部肿块患者行CT导引下经皮穿刺切割活检术的临床资料。结果:经皮穿刺切割活检组织经病理学诊断85例,穿刺活检诊断恶性肿瘤的灵敏度为95.9%、特异度为100%,阳性预测值为100%,阴性预测值为80%,穿刺活检诊断正确率为95.3%。气胸发生率为9.4%,出血发生率为3.5%。结论:CT导引下经皮穿刺切割活检诊断正确率高,并发症轻,是一种安全准确的检查方法。

Objective： To evaluate the clinical diagnosis value of CT-guided percutaneous core needle lung biopsy. Methods： The clinical data of 85 patients with thoracic nodules/masses underwent CT-guided percutaneous core needle lung biopsy were retrospectively analyzed from Feb.2003 to Feb 2012. Results： The sensitivity, specificity, positive prediction value and negative prediction value for the diagnosis of malignant lesions were 95.9%, 100%, 100%, 80% respectively. The accuracy of diagnosis was 95. 3%. The incidence of complicated pneumothorax and pulmonay hemorrhage were 9.4% and 3.5% respectively. Conclusion： CT-guided percutaneous needle lung biopsy is a safely diagnostic technology in thoracic masses with high accuracy and low incidence of complication.
