【摘要】 目的　分析新生儿气胸的X线表现特点 ,以提高其诊断能力。资料与方法　 39例新生儿气胸均摄有仰卧前后位胸片 ,30例同时摄有仰卧水平侧位片 ,19例有 1次或多次随访X线片 ,3例作胸部螺旋CT扫描。结果　 39例新生儿气胸表现为内侧气胸 16例 ,前部气胸 2 2例 ,外侧气胸 1例 ,其中伴有纵隔积气 9例。结论　由于新生儿多采用卧位摄片 ,因此其气胸与年长儿、成人的X线表现不同 ,气体多聚集在胸腔前部和内侧 ,并常伴有纵隔积气。CT能提供更多的病变信息。更多还原

【Abstract】 Objective To analyze radiographic characteristics of pneumothorax in neonates, and to improve its diagnostic quality.Materials and Methods Supine anteroposterior chest film was taken in 39 neonates with pneumothorax, of which additional supine lateral chest film with horizontal projection was simultaneously carried out in 30. One or more radiographic follow-ups were made in 19 cases. Spiral CT scanning was done in 3 cases. The imaging findings were retrospectively analyzed.Results Of the total 39 cases, medial pneumothorax was seen in 16, anterior pneumothorax in 22 and lateral pneumothorax in one. Pneumomediastinum was accompanied in 9 cases.Conclusion For neonates, chest film is usually taken in supine position. Therefor, pneumothorax in neonates makes its appearance different from those seen in adults. In neonates, the pneumothorax is mainly located in the anterior or medial area of the thorax, and pneumomediastinum is commonly accompanied. CT scanning can provide more valuable information.更多还原
