摘　　要：目的分析外伤性支气管断裂的影像表现，提高对本病的认识并指导治疗。方法回顾性分析16例（男性13例，女性3例，年龄17～55岁，平均25．6岁）经手术证实的支气管断裂的影像学表现，并与手术所见作对照分析。结果支气管断裂的影像表现为：支气管中断后的肺不张，“坠落肺”征；气胸或液气胸；纵隔或／和皮下气肿。其“坠落肺”征及颈部纵隔气肿为x线特征性表现。CT检查是x线的补充，能更好显示支气管的中断、移位，尤其多层螺旋CT后处理技术的应用更有价值。结论外伤性支气管断裂容易误诊，其影像表现有其特征性，有助于早期诊断和临床制定治疗方案。Objective To analyze the image of the traumatic bronchial rupture, and to improve the acquaintance and guide the treatment. Methods Retrospectively analyzing the image characteristics of bronchial rupture in 16 cases of patients （ including 13 males and 3 femals, between 17 and 55 years old, with average 25.6 years old） , which were all confirmed by surgical operations and analyzed by contrast. Results The image displays of bronchial rupture are the following ones： atelectasis after bronchial discontinue, ＂downfallen lung＂ sign ; pneumothorax or hydropneumothorax, and mediastinal emphysema or/and pneumoderma. Among them, the ＂downfallen lung＂ sign and jugular - mediastinal emphysema were the characteristic image shows. CT examination was a complementary examination method to X - ray, which could show the discontinue and shift of bronchus better. Especially, the post processing technical application of multi - slice CT （MSCT） had more valuable. Conclusions The traumatic injury of bronchus is liable to be misdiagnosed, but have typically characteristic show in images, which contributes to early diagnosis and to clinically therapeutic schedule -making.
