Displacement of peripherally inserted central catheter (PICC) lines during contrast-enhanced computed tomography examinations is an underappreciated phenomenon. We report a case of iatrogenic PICC line displacement following the power injection of contrast during a computed tomography pulmonary angiogram. During the study, the PICC line was shown to move on 2 occasions, resulting in 2 nondiagnostic studies. We review the available literature on the topic and suggest possible strategies to avoid this phenomenon. Radiologists should be aware of PICC line migration, and it should become common practice to review the catheter tip position after computed tomography examinations.
在对比增强计算机断层扫描检查期间，外周静脉穿刺中心静脉导管（PICC）移位是一种未得到充分认识的现象。我们报告一例在计算机断层扫描肺动脉造影期间进行造影剂高压注射后发生医源性PICC移位的病例。在研究过程中，PICC显示有2次移位，导致2次检查结果无法诊断。我们回顾了关于该主题的现有文献，并提出了避免这种现象的可能策略。放射科医生应意识到PICC移位，并且在计算机断层扫描检查后复查导管尖端位置应成为常规做法。
