叶间裂显影在新生儿呼吸窘迫综合征及早产婴肺鉴别诊断中的价值

Value of Interlobar Fissure Development in Diagnosis of RDS(Respiratory Distress Syndrome) and Prmature Lung

目的复习新生儿呼吸窘迫综合征(RDS)及早产婴肺的X线影像学表现,并探讨叶间裂显影征在二者鉴别诊断中的价值。方法回顾性分析我院新生儿科收治的有完整资料、经临床证实的100例RDS及100例早产婴肺的影像学改变。结果所有患儿均于出生后2~4 h拍首次床旁胸片,二者的共同影像学表现为两肺野透过度不同程度减低,并见分布不一细小颗粒影;不同影像学表现为100例早产婴肺中有41例出现了叶间裂显影征,而100例RDS中无1例出现叶间裂显影征,3例出现了模糊的、不确切的"支气管充气"征。结论叶间裂显影征是鉴别早期RDS(Ⅰ级)及早产婴肺的重要征象,具有重要的意义,当早产婴肺未出现叶间裂显影征时,二者的鉴别就有一定的困难,这时就需要密切结合临床或RDS后期出现的"支气管充气"征相鉴别。

Objective Review X - ray imaging of neonatal respiratory distress syndrome （RDS） and preterm lung, and ex- plore value of interlobar fissure development in diagnosis between them. Methods We retrospectively analyzed the imaging features and changes of 100 RDS cases and 100 preterm lung cases based on complete and confirmed clinical data. Results All the newborn are taken the first X - ray in bed within 2 - 4 hours, the common imaging feature is that the permeability of the two lung lobes reduced to different degree, and different distribution of tiny particles can be seen; The different imaging finding is that there are 45 cases in 100 cases of premature lung with interlobar fissure development; and none in 100 cases of RDS, 3 cases appears vague imprecise air bronehogram. Conclusion Interlobar fissure development is an important feature in diagnosis of RDS （I）, when preterm lung does not appear interlobar fissure development character, the identification can have certain difficulty, so it needs the close combination between clinical and late RDS air bronchogram identification.
