Two cases of ventilator-related neonatal lobar overexpansion with similar radiographic appearance, but probably different pathogenesis, are presented. In one infant, persistent interstitial lobar emphysema was confirmed by markedly decreased perfusion shown on scintigraphy; this information was of great value in predicting the beneficial effect of lobectomy. In the other case, ventilation and perfusion scans indicated functional value of the emphysematous lobe and correctly suggested conservative management. Radioisotope lung scans may provide valuable information regarding lung function in regional pulmonary emphysema associated with assisted ventilation in neonatal respiratory distress syndrome, and thus determine patient management.
本文报告了两例呼吸机相关性新生儿肺叶过度膨胀病例，它们的影像学表现相似，但发病机制可能不同。在其中一名婴儿中，肺灌注闪烁扫描显示灌注明显减少，从而证实了持续性间质性肺气肿；这一信息对于预测肺叶切除术的疗效具有重要价值。在另一例病例中，通气和灌注扫描显示肺气肿肺叶具有功能价值，并正确地提示了保守治疗。放射性核素肺扫描可为新生儿呼吸窘迫综合征辅助通气相关的局限性肺气肿的肺功能提供有价值的信息，从而决定患者的治疗方案。
