目的分析新生儿纵隔积气的X线表现特点,以提高其诊断能力。方法22例新生儿纵隔积气均摄有仰卧前后位胸片,16例同时摄有仰卧水平侧位片,14例有1次或多次随访X线片;有4例胸部螺旋CT扫描。结果22例新生儿纵隔积气表现为胸腺帆征9例,越中线分布9例,纵隔内散在囊状、条状透亮影4例;其中伴有气胸12例。结论新生儿纵隔积气有其X线表现特点,常伴有气胸;而摄片又以卧位正位结合水平侧位显示最佳。CT能提供更多的病变信息。
Objective To analyze the X-ray features of neonatal mediastinum to improve its diagnostic ability. Methods Twenty-two newborn infants with mediastinum had supine chest radiograph, 16 supine lateral radiographs and 14 cases with one or more follow-up radiographs. There were 4 cases of chest CT scan. Results Twenty-two neonates had mediastinal pneumothorax with 9 cases of thymus-saphenous vein, 9 cases with the more midline, and 4 cases with cystic and cystic translucency in the mediastinum. Among them, 12 cases had pneumothorax. Conclusion Neonatal mediastinal gas have its X-ray features, often accompanied by pneumothorax; and radiography in the supine position combined with horizontal lateral display the best. CT can provide more information on the lesions.
