摘　　要：目的探讨螺旋CT直接矢状位扫描在新生儿食管闭锁并食管气管瘘(CEA-TEF)的应用价值。方法5例食管闭锁新生儿,行纵隔螺旋CT矢状位扫描,测量闭锁盲端距离,观察有无食管气管瘘,并与手术结果对照。结果所有病例均获得满意的矢状位CT图像。闭锁食管的的上下段盲端及瘘管显示清楚。按照Gross分型,5例均为Ⅲ型。两盲端之间的距离为0.8～2.1cm。所有数据与手术结果基本相符。结论螺旋CT直接矢状位扫描扫描范围窄、辐射剂量低,且能准确显示闭锁食管盲端位置及合并食管气管瘘等情况,是新生儿CEA-TEF的一种重要检查手段。Objective To evaluate sagittal CT scanning in congenital esophageal atresia and tracheoesophageal fistula （CEA-TEF） in neonates. Methods Direct sagittal CT scanning was performed in 5 neonates with CEA-TEF confirmed by operation. On sagittal CT imaging, the distance between two esophageal pouches were measured, and the presence or absence of tracheoesophageal fistula was determined. The imaging findings was correlated with the surgical findings. Results Sagittal CT images were obtained satisfactorily in all cases. The esophageal pouches and the tracheoesophageal fistula were displayed clearly. According to Gross classification, 1 case was included in type IIIA, and 4 cases in type IIIB. The distance between two esophageal pouches ranged from 0.8 cm to 2.1 cm. The results agreed with the surgical findings. Conclusion Sagittal spiral CT, which employs a limited scanning range and a low radiation dose, and provides fairly accurate information on the tracheoesophageal fistula and the interpouch distance, could be an important examination for CEA-TEF in neonates.
