儿童大叶性肺炎肺实变的超声诊断价值

Clinical value of ultrasonography in the diagnosis of lung consolidation in lobar pneumonia

目的探讨儿童大叶性肺炎实变期的超声图像特征和变化规律,以及超声对其合并症的诊断和鉴别诊断。方法 CT检查证实存在肺实变的大叶性肺炎患儿123例,行超声检查对照,其中67例行X线胸片检查。结果大叶性肺炎实变期肺气体反射消失,呈均匀一致的等回声,支气管呈树枝样分布,血管与支气管伴行,声像图具有特征性改变。与CT比较,超声诊断中下区肺实变符合率较高。结论超声可动态观察大叶性肺炎实变期,对并发症可进行诊断与鉴别诊断,并协助临床治疗。

Objective To explore the features of the ultrasound images and the variation patterns of the lung consolidation in children with lobar pneumonia, as well as the diagnosis and differential diagnosis of its complications. Methods Ultrasonography was performed in 123 children with lobar pneumonia lung consolidation confirmed by X-ray and/or CT, the results were compared and analyzed. Results The lung gas reflection in the lung consolidation of lobar pneumonia disappeared, presenting uniform iso-echoic. The bronchial tube distribution appeared as branches and was accompanied by vessels. The ultrasonogram had characteristic change. Compared with SCT,the ukrasonography diagnosis for the lung consolidation in the middle and lower part had a higher coincidence rate. Conclusion Uhrasonography can be used to confirm the lung consolidation in the lobar pneumonia and observe its change dynamically, to diagnose and differentially diagnose its complications, and to provide assistance in the clinical treatment.
