The central venous catheter (CVC) is associated with numerous complications more so during the process of insertion. We report for the first time how an indwelling catheter was entrapped by a replacement catheter on the same side, after being speared by the introducer needle and guidewire. The diagnosis was made when there was difficulty in removing the old catheter. Subsequently, interventional radiology services were used to define the problem and help in removal of the entrapped catheter. The mechanism of entrapment and the actual procedure used for removal of the catheter is described. The dangers of insertion of a CVC on the same side as a pre-existing one are highlighted.
中心静脉导管（CVC），尤其是在插入过程中，会引发多种并发症。我们首次报告了这样一个病例：一根留置导管被同一侧的置换导管卡住，此前它被穿刺针和导丝刺穿。当难以拔出旧导管时作出了诊断。随后，介入放射科参与明确问题并协助取出被困导管。文中描述了导管被困的机制以及实际的取管操作过程。强调了在已存在CVC的同一侧插入新CVC的风险。
