CT引导下经皮肺穿刺活检对肺内病变的诊断意义

目的探讨CT引导下经皮肺穿刺活检技术及临床应用价值。方法在CT定位引导下使用半自动切割活检针取材，进行病理组织学检查。结果165例病变中，153例穿刺成功，穿刺病理确诊率92．1％，恶性病变假阴性率3．9％，良性病变假阴性率18．9％；并发症发生率33．3％，其中气胸17．0％，肺内出血7．9％，咯血或痰中带血7．3％，皮下血肿1.2％。结论CT引导下经皮肺穿刺活检技术是肺内疑难病变定性诊断的理想方法，具有重要的临床应用价值。

Clinical value of percutaneous biopsy under CT guided on the diagnosis of pulmonary pathological changes

Objective To assess the clinical diagnosis value of CT guided transthoracic core needle biopsy in patients with pathological changes.Methods The pathological diagnosis was performed after getting the tissue by the groovy needle punctured the lesion.Results The 165 patients included 153 focal pulmonary diseases and 12 diffuse pulmonary diseases,the defined pathological diagnostic rate was 92.1%,false negative rate was 3.9%,18.9%in malignant and benign pathological changes;and complication presented in 33.3%,pneumothorax,bleeding,hemoptysis and hypodermic haematoma were 17.0%,7.9%,7.3%and 1.2%,respectively.Conclusion The technique of pulmonary percutaneous biopsy under CT guided is a perfect method for qualitative diagnosis of difficult pulmonary pathological changes:it is of great clinical application.
