| 目的 探讨MSCT对食管闭锁合并远端气管-食管瘘的诊断价值。方法 对35例经食管造影诊断为食管闭锁的新生儿行64层MSCT检查,其中33例经手术确诊,2例放弃治疗。应用MPR及三维表面遮盖显示(SS3D)技术重建图像,并将影像学表现与手术所见相对照。结果 MSCT对35例均可显示食管近端盲端的形态,对26例可显示远端食管的解剖形态,9例远端食管的解剖形态显示不满意。术中所测33例患儿瘘管管径为2.15~3.25 mm(中位管径2.50 mm),近、远端食管盲端的距离为3.56~25.25 mm(中位距离13.33 mm)。26例MSCT图像效果满意的患儿中,MPR重建测得瘘管管径为1.28~3.25 mm(中位管径1.83 mm),近、远端食管盲端的距离为3.25~16.30 mm(中位距离6.90 mm);SS3D重建测得瘘管管径为2.30~3.50 mm(中位管径2.60 mm),近、远端食管盲端的距离为3.50~18.20 mm(中位距离7.70 mm)。结论 MSCT可清晰显示近端食管及多数远端食管的解剖形态、气管-食管瘘的位置,并测量瘘管的管径及食管近端盲端与闭锁远端的距离。 |

| Objective To investigate the diagnostic value of MSCT in esophageal atresia combined with tracheo-esophageal fistula (EA-TEF). Methods A total of 35 newborns with esophageal atresia diagnosed by esophagography underwent 64 slices spiral CT scaning. There were 33 cases confirmed by surgery and 2 cases who gave up treatment. Post-processing techniques including MPR and three dimensional surface shaded displace (SS3D) were performed. Imaging findings were compared with the results obtained by surgical observation. Results Clear morphology manifestations of proximal and distal esophagus were found in 35 and 26 cases separately using MSCT. Unclear manifestations of distal esophagus were found in another 9 cases. The fistula tube diameter measured during operation in 33 cases was 2.15-3.25 mm (median 2.50 mm). The distance between two blind ends of proximal and distal esophagus was 3.56-25.25 mm (median 13.33 mm). Meanwhile, the fistula tube diameters measured by MPR and SS3D reconstruction in 26 cases with satisfactory MSCT images were 1.28-3.25 mm (median 1.83 mm) and 2.30-3.50 mm (median 2.60 mm). The distance between two blind ends of esophagus obtained by MPR and SS3D reconstruction were 3.25-16.30 mm (median 6.90 mm) and 3.50-18.20 mm (median 7.70 mm). Conclusion Morphology findings of proximal esophagus and most distal esophagus as well as the location of EA-TEF can be displayed clearly by MSCT. Moreover, the distance between two blind ends of proximal and distal esophagus can be measured. |
