Aspiration of large amounts of barium sulfate is a rare incident during radiographic contrast procedures. Here we describe two patients, who developed acute dyspnea after aspiration of significant amounts of barium into the lung during an upper gastrointestinal radiographic contrast study. The regions of the lung involved depended on the position of the patients during and after aspiration. Arterial blood gas analysis revealed hypoxemia due to alveolar shunt with V/Q distribution disturbances. Bronchoscopy was performed to extract the contrast medium from the tracheobronchial tree. The patients could be discharged a few days later with normal lung function. Long-term prognosis is generally excellent due to the inert character of barium sulfate, even though impressive radiographic findings remain.
在放射造影检查过程中，大量硫酸钡误吸是一种罕见事件。在此，我们描述两名患者，他们在上消化道放射造影检查期间因大量钡剂误吸入肺而出现急性呼吸困难。肺部受累区域取决于误吸时及误吸后患者的体位。动脉血气分析显示，由于肺泡分流伴通气/血流分布紊乱导致低氧血症。进行了支气管镜检查以从气管支气管树中取出造影剂。患者几天后肺功能恢复正常得以出院。尽管仍有明显的影像学表现，但由于硫酸钡的惰性，长期预后通常良好。
