Changes in pulmonary function, chest X-ray films, and CT were retrospectively studied in patients with sequeae of pulmonary tuberculosis 30 years after pneumonectomy (PNX). Over more than 10 years, VC and FEV1% changed at a rate of 23.2 +/- 8.8 ml and 0.683 +/- 0.688% per year, respectively. In the patients studied 30 years after PNX (N = 30), VC was 900 +/- 210 ml, %VC 31.6 +/- 8.1%, and FEV1% was 67.2 +/- 6.8%. About half of these patients had mild airway obstruction. FEV1% was negatively related to the distance from the hilum to the diaphragm on the mid-clavicular line (on the chest films) divided by body height (r = -0.607). Therefore, we think that the airway obstruction may be due to overextension of the bronchi of middle and lower lobes. Emphysema was not found in 18 patients who had no sign of hyperinflation or herniation of the remaining lung to the PNX side on their CT, but it was found in one patient with these signs.
对肺切除术后30年的肺结核后遗症患者的肺功能、胸部X线片和CT变化进行了回顾性研究。在超过10年的时间里，肺活量（VC）和第1秒用力呼气容积百分比（FEV1%）分别以每年23.2±8.8毫升和0.683±0.688%的速率变化。在肺切除术后30年进行研究的患者（n = 30）中，肺活量为900±210毫升，肺活量百分比为31.6±8.1%，FEV1%为67.2±6.8%。这些患者中约一半有轻度气道阻塞。FEV1%与锁骨中线（胸部X线片上）肺门至膈肌的距离除以身高呈负相关（r = -0.607）。因此，我们认为气道阻塞可能是由于中下叶支气管过度伸展所致。18例CT上无剩余肺向肺切除侧过度充气或疝形成迹象的患者未发现肺气肿，但1例有这些迹象的患者发现有肺气肿。
