剑鞘气管的临床X线研究

目的：通过对剑鞘气管的X线观察，旨在提高对此征的认识。材料与方法：作者总结分析了64例剑鞘气管的临床和X线表现．64例中男性48例，女性16例，年龄45～76岁、本组全部病例均摄有后前位及侧位胸片。结果：从胸片上测量了64例剑鞘气管的冠状径和矢状径，其中气管指数在0．64～0．51者占53％，0．5～0．4者占37％，0．4以下者占10％。结论：X线检查为诊断本症的主要方法和依据，剑鞘气管有助于COPD的诊断。

The Clinico-Radiological Study of Saber-Sheath Trachea

Purpose: This study was carried out for the purpose of to improve recognition by sabersheath trachea. Materials aud methods: The authors analysed the clinical and x-ray manifestations of 64 patients with saber-sheath trachea. There were 48 males and 16 Females, The age of the patients rapged from 45 to 76 years. Routine AP and lateral chest films were done in all patients. Results: The coronal and sagitted diameters of 64 saber-sheath trachea were measured on the chest roentgenograms, of which, The tracheal indices were range from 0. 64 to 0.51 (53%) and 0. 5 to 0. 4 (37%) with of below 0. 4 (10%). Conclusion: The diagnosis was not difficult, the roentgenogram was the main method for the diagnosis. Saber-sheath trachea was valuable in diagnosis of COPD.
