    Migration of retained pacemaker electrodes is rare, with two cases presenting as deep vein thrombosis or asymptomatically. Surgical intervention appears to improve outcomes in these unusual electrode migration events.

    Area of Science:

    • Cardiology
    • Medical Device Complications
    • Vascular Surgery

    Background:

    • Pacemaker implantation is a common procedure for managing cardiac arrhythmias.
    • Retained pacemaker electrodes, though rare, can lead to significant complications.
    • Understanding the migration patterns and clinical impact of these electrodes is crucial for patient management.

    Observation:

    • Two distinct cases of pacemaker electrode migration are presented.
    • One case manifested as deep vein thrombosis (DVT), an unusual presentation.
    • The second case was asymptomatic, discovered incidentally on a chest X-ray.

    Findings:

    • A literature review identified only 13 previous cases, totaling 15 cases.
    • Four deaths were reported among the 15 cases.

  • No correlation was found between migration site, infection, or thrombosis and patient morbidity.
  • Surgical treatment was associated with a better prognosis.

    • Implications:

    • This study highlights the potential for serious, albeit rare, complications from retained pacemaker electrodes.
    • Early detection and appropriate management, particularly surgical intervention, may improve patient outcomes.
    • Further research into the long-term effects and optimal management strategies for electrode migration is warranted.
