The incidence of catheter fragment induced by iatrogenic accident has been increasing because of frequent use of intravenous catheters and catheterization in daily practice. Migrated intravascular fragments from broken catheters were retrieved transcutaneously in four cases. All fragments were removed safely using biotome, multipurpose grasping forceps and basket catheter. But in a case which the fragment was lodged in the pulmonary artery, retrieval was not easy and it took many times. Fragments lodged in the right ventricle and in the pulmonary artery cause many complications including deaths. So broken fragments should be removed as soon as possible, before it migrated to there.
由于在日常实践中频繁使用静脉导管和进行导管插入术，医源性事故导致的导管碎片发生率一直在上升。在4例病例中经皮取出了断裂导管迁移至血管内的碎片。使用活检刀、多功能抓取钳和网篮导管安全地取出了所有碎片。但在1例碎片嵌顿于肺动脉的病例中，取出并不容易，花费了很多时间。碎片嵌顿于右心室和肺动脉会导致包括死亡在内的许多并发症。因此，断裂的碎片应在迁移至这些部位之前尽快取出。
