Partial liquid ventilation using perfluorocarbons is a therapy that was once frequently used in paediatric populations for patients with severe respiratory distress. Perfluorocarbon is a non-toxic, insoluble and radiopaque vector through which improved gas exchange can occur. Two previous cases have been reported of persistent perfluorocarbon residua, identified on imaging years after receiving liquid ventilation therapy. We report a case of perfluorocarbon detection on a CT scan 15 years after liquid ventilation at 3 months of age, and propose the probable mechanism of its appearance. The importance of considering the imaging appearances of 'pseudo-calcifications' as a long-term sequela to perfluorocarbon liquid ventilation is emphasised.
使用全氟化碳进行部分液体通气是一种曾经常用于患有严重呼吸窘迫的儿科患者的治疗方法。全氟化碳是一种无毒、不溶且具有放射不透性的载体,通过它可实现改善气体交换。之前已有两例报告称,在接受液体通气治疗数年之后的影像学检查中发现了持续性全氟化碳残留。我们报告了一例在3个月大时接受液体通气治疗15年后的CT扫描中检测到全氟化碳的病例,并提出了其出现的可能机制。强调了将“假钙化”的影像学表现视为全氟化碳液体通气长期后遗症的重要性。
