改良CT引导下经皮肺穿刺活检对肺疾病的诊断价值

Clinical diagnostic value of percutaneous lung biopsy by improved CT fluoroscopy

目的:评价改良CT引导下经皮肺穿刺活检的临床应用价值。方法:回顾性分析经手术或病理证实的CT引导下经皮肺穿刺活检44例。采用21G穿刺抽吸针,选择最佳层面、进针点、进针角度和深度及多点抽吸。结果:44例均获满意标本,穿刺成功率100%,病理学确诊98%,病理诊断恶性肿瘤31例,良性肿块13例。结论:改良CT引导下经皮肺穿刺活检对肺部病变确诊率高,并发症少,是一种安全有效、简便实用的检查方法,值得推广使用。

Objective：To evaluate the clinical application value of percutaneous lung biopsy by improved CT fluoroscopy.Methods：Forty-four cases were analyzed percutaneous lung biopsy by improved CT fluoroscopy which were proved by operation or pathology with the puncture needle.The main points are：choose the best layer,point,angle,depth,draw and obtaining at many points.Results：All 44 lung lesions were successfully conducted biopsy through CT-guided fine needle aspiration,and the pathological confirmed diagnosis rate was 98%,pathological diagnosis 31 malignant tumors and 13 benign tumors.Conclusions：The pereutaneous lung biopsy by improved CT fluoroscopy is accurate,less of complication.It is a safe,effective,simple and practical way for diagnosing lung diseases.
