In a retrospective study, the authors evaluated the initial and follow-up radiographs and ventilation perfusion (V/Q) scans of 12 boys and girls with lobar emphysema who were treated conservatively and were followed up for a median of 3 years (range, 6 months to 12 years). All 12 boys and girls underwent anteroposterior and lateral chest radiography at admission and at varying intervals thereafter. Ten patients underwent V/Q lung scanning; six of these procedures were performed within 4 weeks of initial radiography. Six patients underwent follow-up V/Q scanning. Thoracic computed tomography was performed in four patients at admission. In all 12 cases gradual improvement in symptoms was paralleled by improvements in serial chest radiographs and, in six cases, by improvements in V/Q scans. The affected lobe appeared to be less hyperinflated on follow-up radiographs. For those children who showed functional improvement, ventilation improved more than perfusion, as demonstrated on the V/Q scans. At initial radiography the adjacent "collapsed" lobe was seen to function well, suggesting that it was only compressed.
在一项回顾性研究中，作者评估了12例接受保守治疗且中位随访时间为3年（范围6个月至12年）的小儿大叶性肺气肿患者的初始及随访X线胸片和通气灌注（V/Q）扫描结果。所有12例患儿在入院时及之后不同时间点均进行了胸部正侧位X线检查。10例患者接受了V/Q肺扫描；其中6例在初次X线检查后4周内进行。6例患者接受了随访V/Q扫描。4例患者在入院时进行了胸部计算机断层扫描。在所有12例病例中，症状逐渐改善，同时系列胸片也有所改善，6例患者的V/Q扫描结果也有所改善。随访X线片显示患侧肺叶过度充气情况减轻。对于那些功能改善的儿童，V/Q扫描显示通气改善比灌注改善更明显。在初次X线检查时，可见相邻的“萎陷”肺叶功能良好，提示其仅为受压。
