【摘要】：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2.50mm),近、远端食管盲端的距离为3.56~25.25mm(中位距离13.33mm)。26例MSCT图像效果满意的患儿中,MPR重建测得瘘管管径为1.28~3.25mm(中位管径1.83mm),近、远端食管盲端的距离为3.25~16.30mm(中位距离6.90mm);SS3D重建测得瘘管管径为2.30~3.50mm(中位管径2.60mm),近、远端食管盲端的距离为3.50~18.20mm(中位距离7.70mm)。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。
[Abstract]:Objective to evaluate the diagnostic value of MSCT in esophageal atresia with distal tracheoesophageal fistula. Methods Thirty five newborns with esophageal atresia diagnosed by esophagography were examined with 64-layer MSCT, of which 33 cases were confirmed by operation and 2 cases gave up treatment. MPR and 3 D surface shaded display (SS3D) were used to reconstruct the images and the imaging findings were compared with those of the operation. Results MSCT could show the morphology of the proximal end of esophagus in 35 cases and dissatisfied with the anatomical morphology of distal esophagus in 9 cases in 26 cases. The diameter of fistula was 2.15 ~ 3.25 mm (median diameter 2.50mm) in 33 cases during operation. The distance between proximal and distal esophageal blind end was 3.56~25.25mm (median distance 13.33mm) .26 cases with satisfactory results of MSCT images were found to be 1.28~3.25mm (median diameter 1.83mm). The distance between the blind end of distal esophagus was 3.25~16.30mm (median distance 6.90mm) and the diameter of fistula measured by SS3D reconstruction was 2.30~3.50mm (median diameter 2.60mm), and the distance of proximal and distal blind end of esophagus was 3.50~18.20mm (median distance 7.70mm). Conclusion MSCT can clearly show the anatomy of proximal esophagus and most distal esophagus, the location of tracheo-esophageal fistula, and measure the diameter of fistula and the distance between the proximal end of esophagus and the distal end of atresia.
