膈肌破裂的CT表现(附18例手术对比分析)

CT Features of the Diaphragmatic Rupture:Comparison with Surgical Results

目的探讨膈肌破裂（diaphragmatic rupture,DR）的CT表现。资料与方法回顾性分析18例DR患者的CT表现特征,并与手术所见对比。结果 DR的CT表现为膈肌中断,部分膈肌不能辨认,膈肌增厚和膈疝征等。受DR机制、部位等因素影响,CT各征象的显示率有差异。结论多数DR具有特征性的CT表现。破口大小为2~10cm且合并膈疝的左侧DR的CT各征象显示率较高。

Objective To study CT manifestations of diaphragmatic rupture（DR）.Materials and Methods CT features of 18 patients with DR were analyzed retrospectively.The CT findings were compared with surgery.Results CT features of DR included diaphragmatic discontinuity,diaphragmatic thickening and intrathoracic herniation of abdominal viscera.The display rate of CT was affected by various factors such as machanism and position of DR.Conclusion Higher display rate was occurred in left DR with the size of 2 to 10 cm,accompanied with diaphragmatic hernia.
