目的探讨急性成人呼吸窘迫综合征的胸部X线影像表现。方法回顾性地分析25例急性成人呼吸窘迫综合征患者的临床及影像学资料,归纳所有患者的临床表现及X线特点。结果 X线主要征象有:ARDS早期为间质性肺水肿期,出现于发病后12～24小时,表现为(部分病例可无异常)肺纹理增粗、模糊,尤以肺门部明显,有时可见小片状阴影或“面纱征”。ARDS中期为肺泡性肺水肿期或渗出期,表现为两肺广泛的斑片状模糊阴影。ARDS后期为纤维增生期,表现为肺间质纤维化,肺野可见少许索条状影。结论床旁胸部X线平片在ARDS的诊断和治疗效果判定中具有重要的作用。
Objective To investigate the chest X-ray findings of acute adult respiratory distress syndrome. Methods The clinical and imaging data of 25 patients with acute respiratory distress syndrome were retrospectively analyzed. The clinical manifestations and X-ray findings of all patients were summarized. Results The main signs of X-ray were: early stage of interstitial pulmonary edema ARDS appeared in 12 to 24 hours after onset, showed (in some cases without abnormalities) lungs thickening, blurred, especially in the hilar obvious, and sometimes Visible little flake or “veil levy.” ARDS mid-term pulmonary alveolar pulmonary edema or exudative period, the performance of a wide range of patches of lung-shaped fuzzy shadow. ARDS late stage of fibrosis, manifested as interstitial fibrosis, lung field can be seen a little cable-like shadow. Conclusion The bedside chest radiograph plays an important role in the diagnosis and treatment of ARDS.
