Elemental mercury injected intravenously can distribute throughout the body, forming microemboli in organs. A case study found widespread mercury microemboli and high serum mercury levels, yet no chronic intoxication signs.

Area of Science:

  • Toxicology
  • Vascular Medicine
  • Neurology

Background:

  • Elemental mercury (Hg) is a toxic metal.
  • Intravenous (IV) injection of elemental mercury is a rare but serious exposure route.
  • Understanding mercury distribution and toxicity is crucial for clinical management.

Observation:

  • A 39-year-old male self-administered elemental mercury intravenously into his cubital vein.
  • The exposure was incidentally discovered during medical treatment.
  • Widespread microemboli of metallic mercury were identified in multiple organs, including lungs, liver, spleen, kidneys, and the central nervous system.

Findings:

  • High serum concentrations of both dissolved and oxidized mercury were detected.
  • Despite extensive microembolization, overt signs of chronic mercury intoxication or organic functional disturbance were not apparent.

  • The distribution pattern suggests rapid systemic dissemination following IV injection.

    • Implications:

    • This case highlights the potential for severe systemic distribution of elemental mercury after IV injection.
    • It underscores the importance of considering mercury toxicity in patients with unexplained microemboli.
    • Further research into the long-term effects and management strategies for elemental mercury vascular injection is warranted.
