典型的气胸X线诊断并不困难,但有时对一些X线征象不十分明显者则容易被忽视。另外在估算气胸量的多少时往往出入较大,对此尚有进一步研究和探讨之必要。 检查方法:凡临床怀疑有气胸的病例,不论是摄片还是透视,均应曝光前嘱患者作深呼气后进行,方能使气胸线显示更为清楚。 气胸量的估算:当脏层或壁层胸膜破裂后空气进入胸膜腔,改变原来胸膜腔内负压状态,压迫肺组织使其向根部萎缩,萎陷的程度取决于胸膜腔内空气量的多少,故可根据患侧肺的萎陷程度来估算气
A typical pneumothorax X-ray diagnosis is not difficult, but sometimes not obvious for some X-ray signs are easily overlooked. Also in the estimation of the amount of pneumothorax often more access, this is still necessary for further study and discussion. Inspection methods: Where there is clinical suspicion of pneumothorax cases, either radiography or fluoroscopy, patients should be exposed before the epigastern deep breath to make the pneumothorax display more clearly. Estimation of pneumothorax: When the visceral or parietal pleura rupture air into the pleural cavity, changing the original state of pleural cavity negative pressure, oppression of the lung tissue to the root atrophy, the degree of collapse depends on the amount of air in the pleural cavity , So according to the degree of ipsilateral lung collapse to estimate the gas
