摘要: 目的:分析食管癌放疗后食管-纵隔瘘的CT表现,探讨螺旋CT对食管癌放疗后继发食管-纵隔瘘的诊断价值。方法:对10例临床确诊为食管癌。经放射治疗后发生食管瘘患者行CT扫描,并进行多平面重建和仿真内镜,总结其CT表现,并与内窥镜检查作比较。结果:CT成功显示了食管-纵隔瘘的瘘口,并显示了瘘口的并发症;纵隔炎,仿真内镜显示了瘘口的形状,并与消化内镜相符合。结论:螺旋CT断层扫描与仿真内镜能显示食管瘘的瘘口及其并发的纵隔炎症,为食管癌放疗后并发食管-纵隔瘘的治疗提供可靠的影像学依据。Abstract: Objective: To analyze the characteristics of mediastinoesophgeal fistulas Subsequent Esophageal Carcinoma after radiotherapy on multislice CT(MSCT),and evaluates the diagnostic value of MSCT.Methods: MSCT imaging of 10 patients who suffered with mediastinoesophgeal fistulas secondary to carcinoma of esophagus after radiotherapy were retrospectively studied.The CT scans involved axial computerized tomography and multi-plane reconstruction(MPR) and virtual bronchoscopy made on the workstation.The imaging manifestations were correlated with endoscope fingdings.Results: The CT imaging shows the fistulas successfully,and the mediastinitis were found in all the patents.The appearances of the fistula manifested on the bronchoscopy were consistent to the endoscope findings.Conclusion: MSCT and its virtual bronchoscopy are reliable for showing and assessing the mediastinoesophgeal fistula and its complications,thus afford a reliable imajings evidenced in proceed treatment.
