摘要
目的探讨肺组织创伤早期胸膜下CT表现及意义。方法收集本院2009-2011年胸部外伤初诊时无明显肺及胸膜损伤征像,而24-48小时复诊时出现迟发性肺及胸膜创伤表现者85例,共计96侧肺。回顾性分析急诊胸部CT(4小时内)此类胸部创伤的早期影像表现特征。结果初诊时此类肺部创伤主要表现为胸膜下的细微变化,大致可分三类:胸膜下气泡影、胸膜下纹理增多、胸膜下弧线影。初诊CT发现阳性征象者占97.0%(93/96),其早期征象出现比例如下:胸膜下气泡影病例者占55.2%(53/96),胸膜下纹理增多占22.9%(22/96),胸膜下弧线影占18.9%(18/96),无异常表现者占3.0%(3/96)。相比胸膜下气泡影是出现迟发肺及胸膜创伤表现较重,且影像表现变化复杂的一种早期表现;胸膜下纹理增多者次之。胸膜下弧线影病例则是出现迟发肺及胸膜损伤相对较轻的一种早期表现。结论胸膜下气泡影、胸膜下纹理增多、胸膜下弧线影的形成与肺组织及胸膜创伤有密切关系,提高对此类影像表现的认识,有力于提高早期胸膜或肺创伤的诊断率,对临床诊治工作有一定的指导意义。
Objective To explore the lung tissue trauma early subpieural CT manifestations and significance. Methods We collected 2009-2011 chest trauma to begin with no obvious lung and pleural damage sign like, takes 24-48 hours for the return visit occurs when the late-occurred lung and pleural trauma presenters 85 examples, a total of 96 side lung. Retrospective analysis of emergency chest CT (4 hours) this kind of chest trauma early image features. Results This kind of lung trauma to begin with the main performance for the subpleural subtle change, can be roughly divided into three types: the subpleural gas bubble, texture increase, circular shadow. Both CT found positive sign is 97.0% (93/96), the pro- portion of early signs are as follows: the subpleural gas bubble those cases was 55.2% (53/ 96), the subpleural texture increased 22.9% (22/96), the subpleural line shadow accounted for 18.9% (18/96), no abnormalities, presenters accounted for 3.0% (3/96). Compared with the subpleural gas bubble is appeared late lung and pleural trauma performance heavier, and image performance change complex an early performance, the subpleural texture increasing person is the second smallest, and in the subpleural line shadow cases is appeared late lung and pleural damage relatively light an early performance. Conclusion The subpleural gas bubble, and in the subpleural texture increase, and in the subpleural line shadow of the formation and lung tissue and pleural trauma have close relations, and improve the performance of such image understanding, for clinical work has certain guiding significance.
