Summary

Arterial gas embolism (AGE) is a rare complication of medical procedures. Early diagnosis with cranial CT scans is crucial for identifying AGE and assessing resulting ischemic stroke and myocardial infarction.

Area of Science:

  • Neurology
  • Cardiology
  • Radiology

Background:

  • Arterial gas embolism (AGE) is a serious iatrogenic complication of invasive medical procedures.
  • Diagnosis of AGE is challenging without high clinical suspicion.

Observation:

  • A 67-year-old male with cardiac history presented with malaise and fever.
  • Neurological deficits including loss of consciousness, facial paralysis, and Babinski sign were observed.
  • ECG revealed atrial fibrillation and ST elevation, suggesting myocardial infarction.

Findings:

  • Cranial CT scans identified serpiginous air in vascular structures, indicative of AGE.
  • Subsequent CT scans showed resolution of air and evidence of ischemic stroke in multiple cerebral arteries.
  • Clinical and radiological findings suggested AGE leading to stroke and myocardial infarction.

Implications:

  • Accidental air entry into peripheral veins is the likely cause of AGE in this case.
  • Early cranial CT is vital for diagnosing AGE.
  • Serial CT scans help evaluate the extent of embolic consequences, such as ischemic stroke and myocardial infarction.
