目的 探讨急性左心衰肺水肿在胸部X线影像学的表现。方法 回顾性分析89 例具有完整临床资料的急性左心衰肺水肿患者的胸部X线表现,所有病例均经临床随访证实。结果 89 例患者中,87例心影有不同程度增大,肺部异常表现在肺瘀血9例,间质性肺水肿43例,肺泡性肺水肿37例。合并水平叶间裂增厚及单侧或双侧胸腔积液46例。结论 肺水肿胸部异常X线改变可以比临床表现出现得早。提高对急性左心衰肺水肿X线诊断的认识,对协助临床诊断有着重要的意义。
Objective To investigate the chest X-ray findings of acute left heart failure pulmonary edema. Methods A retrospective analysis of 89 patients with complete clinical data of acute left heart failure pulmonary edema in patients with chest X-ray findings, all cases were confirmed by clinical follow-up. Results Among the 89 patients, 87 cases of cardiac shadow increased in varying degrees. The abnormal lung manifestations included 9 cases of pulmonary blood stasis, 43 cases of interstitial pulmonary edema and 37 cases of alveolar pulmonary edema. Forty-six patients with thickened interlobular fissure and unilateral or bilateral pleural effusion. Conclusions Abnormal X-ray changes in pulmonary edema may appear earlier than clinical manifestations. To improve the understanding of X-ray diagnosis of acute left heart failure pulmonary edema is of great significance to assist in clinical diagnosis.
