新生儿肺透明膜病的影像分析

Imaging analysis of pulmonary hyaline membrane disease in newborns

目的探讨新生儿肺透明膜病的影像特征。方法回顾性分析经临床及病理证实的80例新生儿肺透明膜病的X线表现。结果本组80例中25例表现为肺野呈细网格状改变及弥散颗粒状阴影,40例表现为肺野透光度减低、斑片状密度增高影,肺野透光度明显下降,心缘及膈面模糊;15例表现为“白肺”;其中合并肺炎20例,合并动脉导管未闭10例,并发肺出血15例,并发气胸5例。结论普通胸部X线检查是诊断新生儿肺透明膜病的可靠方法,也是可用于考虑这些病人的临床状况并需立刻做出诊断的手段之一。支气管充气征是本病具有的特征性表现。

Objective To investigate the imaging features of pulmonary hyaline membrane disease (PHMD) in newborns.Methods X-ray findings of 80 newborns with clinically and pathologically proved PHMD were analyzed retrospectively.Results Twenty-five of 80 newborns with PHMD had fine reticular changing and diffuse granular opacities in the lung field,40 had decreased hyalinization of lung field,mottling shadows with high density,and cardiac border and diaphragmatic face hazy.15 presented as “white lung”,of them,20 complicated with pneumonia,10 had patent ductus arterious,15 complicated with pulmonary hemorrhage,and 5 complicated with pneumothorax.Conclusion Conventional X-ray chest radiography is considered the most reliable diagnostic tool to study PHMD in newborns and one of the few diagnostic investigations which can be used considering the clinical situation of these patients and the need of a prompt diagnosis.The aerial bronchogram is a characteristic finding of PHMD.
