When removal of an endocardial pacemaker electrode became necessary in a patient with congestive myocardiopathy, it proved to be incarcerated. Therefore, a portion of it had to be left in site after cutting the external end of the pacing catheter. During follow-up examinations the electrode was seen to migrate in the large veins and finally was found embolized into a pulmonary artery. While there have been publications on the migration of retained pacemaker electrodes before, to our knowledge this represents the first case reported with pulmonary embolization of the migrating fragment.
对于一名患有充血性心肌病的患者，当必须移除心内膜起搏器电极时，发现电极已嵌顿。因此，在切断起搏导管的外部末端后，不得不将其一部分留在原位。在随访检查中，发现电极在大静脉中移位，最终发现其栓塞到肺动脉中。虽然之前已有关于保留的起搏器电极移位的报道，但据我们所知，这是首例报道的移位碎片发生肺栓塞的病例。
