CT引导一次性半自动活检针经皮肺结节穿刺活检46例分析

Percutaneous lung nodule aspiration biopsy guided by CT with one time semi,automatic biopsy needle(An analysis of 46 cases)

目的探讨CT引导一次性半自动活检针经皮肺穿刺活检对诊断肺部结节价值。方法收集46例常规病检有困难的肺结节病例,应用一次性半自动活检针,在CT引导下做经皮穿刺活检,分析其诊断的准确性,安全性。结果46例病人,获得明确病理诊断40例(87%),包括恶性肿瘤24例,结核10例,炎性病变4例,其它良性病变2例。有症状并发症发生率13%(6/46),包括1例严重气胸和5例少量咯血。结论CT引导一次性半自动活检针经皮肺穿刺活检因取材确切、定位准确,对肺部结节的病理诊断具有重要的实用价值。

Objective To investigate the diagnostic value of percutaneous lung nodule aspiration biopsy under CT quided with one time semi,automatic biopsy needle. Methods 46 cases with lung nodule received hard to make a routine biopsy. which were collected. Using one time semi,automatic biopsy needle under CT guided,the percutaneous lung biopsy was performed.It′s diagnostic accuracy and safety were analyzed retrospectively.Results Among 46 cases,definitive pathological diagnosis was obtained in 40 cases(87%),including malignant tumor in 24 cases,lung tuberculosis 10 cases,inflammatory lesion 4 cases and other benign lesion 2 cases. The complication rate of this procedure was 13%(6/46),including severe pneumothorax in 1 case and mild hemoptysis 5 cases. Conclusion Because of this procedure has accurate sampling and precise localization,so,it posseses important practical value for pathological diagnosis of lung nodules.
