摘要
目的 :探讨食管癌放射性气管狭窄的CT特征。材料和方法 :回顾性分析 13例食管癌放射性气管狭窄患者临床及CT表现。结果 :13例食管上中段癌患者放射治疗后一段时间内出现气管或支气管狭窄 ,且狭窄段出现在放射野内 ,管壁厚度 >3mm ,且临床表现与气管狭窄程度相平行。结论 :放射性气管狭窄有其特征性CT表现。CT扫描有助于放射性气管狭窄诊断及鉴别诊断。
Purpose: To study the diagnostic value of CT in tracheobronchial stenosis after radiation.Materials and Methods: The clinical and CT findings in 13 cases of esophagus carcinoma with tracheobronchial stenosis after radiation were studied retrospectively. Results: The results showed (1)Tracheobronchial stenosis was located in radiation field. (2)The wall of tracheal was more than 3 mm, the lumen narrow less than 9 mm. (3)It happened 6 months after radiation. (4)The clinical symptom correlated with the degree of tracheobronchial stenosis. conclusion: CT is an ideal method and most accurate in defining tracheobronchial stenosis and the degree of airway obstruction. CT examination makes it possible to determine the diagnosis of the lesions.
