Subclavian venepuncture caused subcutaneous emphysema, leading to pacemaker malfunction. Air in the generator pocket insulated the anodal plate, causing device dysfunction in a dual-chamber pacing system.

Area of Science:

  • Cardiology
  • Medical Devices
  • Surgical Complications

Background:

  • Physiologic dual-chamber pacing systems offer advanced cardiac rhythm management.
  • Pacemaker dependency necessitates reliable device function for patient survival.

Observation:

  • A patient with a newly implanted dual-chamber pacing system presented with device malfunction shortly after implantation.
  • The malfunction was linked to subcutaneous emphysema originating from the subclavian venepuncture procedure.

Findings:

  • Air accumulation within the pacemaker generator pocket was identified as the direct cause of malfunction.
  • The emphysema led to insulation of the unipolar anodal plate, resulting in device dysfunction.

Implications:

  • This case highlights a rare but critical complication of subclavian venepuncture in pacemaker implantation.
  • Awareness of this complication is crucial for clinicians managing patients with cardiac pacing devices.
  • Preventive measures during venepuncture may reduce the risk of such device-related issues.
