CT导向经皮肺穿刺活检的临床应用

Clinical Application of Percutaneous Lung Biopsy by CT Fluoroscopy

目的:分析在CT导向下经皮肺穿刺活检技术及临床应用价值。提高肺部团块状、结节样病变取材成功率和临床诊断准确率。方法:探讨肺部团块状、结节样病变在CT导向下经皮肺穿刺活检技术,并追踪随访其病理及手术结果。结果:在CT导向经皮肺穿刺活检31例中,一次取材成功29例,第一次取材未能得到病理结果,再行第二次取材成功的2例。一次取材成功率94%,病理确诊率100%。结论:CT导向经皮肺穿刺活检定位取材准确,病理确诊率高。是肺部团块状,结节样病变的诊断和鉴别诊断的主要手段之一。

Objective： To evaluate the value of CT fluoroscopy to make percutaneous lung biopsy. To in- crease the puncture success rate and the diagnosis accurate rate in the mass or nodular of lung. Method： To study the mass or nodular of lung which make percutaneous lung biopsy by CT fluoroscopy, follow up their pathological diagnosis and surgical results. Results： 31 cases underwent percutaneous lung biopsy by CT flu- oroscopy. 29 cases succeed in making percutaneous lung biopsy,2 cased failed and made second percutane- ous lung biopsy. The puncture success rate was 94%, the pathological diagnosis accurate rate was 100%. Conclusion： CT guidance percutaneous lung biopsy is an accurate method in puncture , which has high ac- curate rate in pathological diagnosis. And it is a major method in the diagnosis, differential diagnosis of the mass or nodular of lung.
