目的 探讨心原性肺水肿的X线胸片的表现 ;提高对肺水肿的X线诊断的认识。方法 选取 31例诊断明确的心原性肺水肿患者 ,分析其治疗前后的正、侧位胸片的X线表现。结果 31例患者的X线征象有 :反转血流现象 2 9例 ,KerleyB线和A线各有 18例和 5例 ,胸膜下水肿和支气管袖口征各有 15例和 18例 ,肺门混浊征和肺纹理模糊 2 4例 ,蝶翼征和运动边缘线各有 5例和 2例 ,单侧肺水肿和两肺不对称的肺水肿 6例 ,胸腔积液 2 4例 ,心脏阴影扩大 2 9例。结论 反转血流现象 ;KerleyB线形成 ;肺门混浊征和肺纹理模糊 ;以及少量胸腔积液 ,心胸比例增大等应为心源性肺水肿常见的且较为特征性的X线胸片表现。
Objective To investigate the manifestations of X-ray of cardiogenic pulmonary edema and to improve the understanding of X-ray diagnosis of pulmonary edema. Methods Totally 31 patients with definite diagnosis of cardiogenic pulmonary edema were selected and their X-ray findings of positive and lateral radiographs before and after treatment were analyzed. Results 31 cases of X-ray signs: reverse blood flow in 29 cases, KerleyB line and A line in 18 cases and 5 cases, subpleural edema and bronchial cuffs in each of 15 cases and 18 cases, hilar cloudy 24 cases of vague signs and blurred lungs, 5 cases and 2 cases of wing and motion margin, 6 cases of unilateral pulmonary edema and asymmetric pulmonary edema of both lungs, 24 cases of pleural effusion and 2 enlarged heart shadow 9 cases. Conclusions Reverse blood flow phenomenon; KerleyB line formation; hilar hyperechiasma and blurred lungs texture; and a small amount of pleural effusion, cardiothoracic ratio should be cardiogenic pulmonary edema common and more characteristic X-ray findings .
