创伤性支气管断裂的影像学诊断

Radiographic diagnosis of traumatic bronchial rupture

目的探讨创伤性支气管断裂的胸片和CT表现,从而做到早期诊断和治疗。方法回顾性分析21例经手术或支纤镜检查证实的创伤性支气管断裂的X线胸片和CT表现。结果支气管断裂的主要影像学表现为:气管支气管气柱中断,肺不张,肺下垂征,纵隔及皮下气肿,气胸或液气胸;CT检查还能显示气管支气管管壁的缺损,管腔狭窄、堵塞,移位或成角畸形。结论联合应用胸片和CT检查,对支气管断裂的早期诊断有重要价值。

Objective To study the X-ray and CT findings of traumatic bronchial rupture for early radiographic diagnosis and treatment. Methods The chest plain X-ray films and CT images of 21 patients with traumatic bronchial rupture confirmed by operations or bronchoscopy were retrospectively analyzed. Results The main radiographic findings of traumatic bronchial rupture included interrupted tracheobronchial air column, atelectasis, lung ptosis, pneumomediastinum and subcutaneous emphysema, pneumothorax or hydropneumothorax. CT scanning also revealed tracheobronchial wall defect, bronchostenosis, and bronchial occlusion, displacement and angulation. Conclusion Chest plain X-ray film combined with CT scanning has important values for early diagnosis of traumatic bronchial rupture.
