空气支气管征

Air-bronchogram

本文分析38例肺叶肺段病变。在肺叶阴影空气支气管征阳性病例中,肺叶支气管正常21例,肺叶支气管明显狭窄9例,在肺段阴影空气支气管征阳性病例中,肺段支气管正常5例;肺段支气管明显狭窄3例。在12例支气管明显狭窄病例中,中央型肺癌5例;肺结核2例:慢性肺炎合并支气管扩张2例,先天性肺囊肿,血块堵塞支气管与怖梗塞各1例。我们认为:肺叶肺段阴影内发现空气支气管征阳性,只能除外支气管完全梗阻性病变,而不能除外支气管不完全梗阻性病变。因此仅根据空气支气管征阳性不能鉴别肺癌,肺结核与肺炎。

38 cases of disorders of the lung lobes and segments were analysed. There were 9 cases of marked narrowing of lobar bronchi showed in 30 cases of air-bronchogram in lobarshadows and 3 cases showed narrowing in segmental bronchi in 8 cases of air-bronchogram in segmental shadows.There were 5 cases of central lung cancer, 2 cases of pulmonary tuberculosis, 2 cases of chronic pneumonia complicated with bronchiectasis and each 1 case of congenital pulmonary cyst, blood plot impaction and pulmonary infaction ni 12 cases of marked bronchial stenosis.Authors concluded that air-bronchogram in lobar or segmental shadows can only exclude the possibility of complete obstruction of the bronchus, but can not exclude the partial obstruction. It is impossible to make the differential diagnosis for lung cancer, pulmonary tuberculosis and pneumonia simply by air-bronchogram.
