摘要
目的评价CT引导下经皮穿刺肺活检术在诊断肺部弥漫性病变中的价值。方法回顾性分析68例接受CT引导下经皮穿刺肺活检术的肺部弥漫性病变患者的资料。主要影像学改变包括弥漫性网状结节或结节、弥漫性线网状影、弥漫性磨玻璃样密度。采用18CT或20G穿刺活检针进行活检。结果68例患者均一次性穿刺成功,且均能做出明确诊断。其中恶性病变19例,包括细支气管肺泡癌9例,转移癌10例;良性病变49例,为血型播散型肺结核27例,结节病8例,矽肺与煤工肺7例,间质性肺炎2例,肺泡蛋白沉着症4例,过敏性肺炎1例;主要并发症为气胸和出血,并发症的发生率为17.65%。结论在肺部弥漫性疾病的诊断中,CT引导下经皮肺穿刺肺活检术是一种实用、安全、并发症少、准确性高、创伤小的定性诊断方法。
Objective To assess the diagnostic value of the CT-guided percutaneous lung biopsy in diffuse lung diseases.Methods CT-guided percutaneous lung biopsy was performed using 18G or 20G biopsy needle in 68 patients with diffuse lung diseases.The main imaging changes of these patients included network of diffuse nodular or nodular,diffuse reticular lines shadow and diffuse ground-glass density in the lungs.Results Punctures were successful in all 68 patients,and the diseases were clearly diagnosed,including 19 patients with malignant（9 bronchioloalveolar carcinoma and 10 metastatic carcinoma） and 49 with benign（27 disseminated pulmonary tuberculosis,8 sarcoidosis,7 silicosis and coal worker＇s lung,2 interstitial pneumonia,4 pulmonary alveolar proteinosis allergic and 1 pneumonia） lesions.The major complications of puncture were pneumothorax and bleeding,and the incident rate of complications was 17.65%.Conclusion CT-guided percutaneous lung biopsy is a useful,safe technique with low complications,high accuracy rate for the diagnosis of diffuse lung diseases.
