Summary

Infective endocarditis caused by Staphylococcus aureus can lead to severe complications like brain abscess and disseminated intravascular coagulation. Dental management requires careful physician consultation, prioritizing oral hygiene and pain relief over immediate extractions.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Dentistry

Background:

  • Infective endocarditis (IE) is a serious infection with increasing nosocomial acquisition and broader pathogen spectrum.
  • Staphylococci, not typically oral flora, are emerging as significant causative agents in IE.
  • Immunosuppression plays a role in IE pathogenesis.

Observation:

  • A case of IE caused by Staphylococcus aureus is presented.
  • The patient developed disseminated intravascular coagulation, multiple septic infarcts, and a frontal lobe brain abscess.
  • Dental extractions were complicated by hemorrhage, and abdominal hemorrhage was the immediate cause of death.

Findings:

  • Staphylococcus aureus can cause severe IE with systemic complications.
  • Dental interventions in IE patients require careful planning and physician collaboration.

  • Delayed post-extraction hemorrhage and abdominal hemorrhage complicated the case.

    • Implications:

    • Dental management for IE patients must consider the specific pathogen and complications.
    • Prioritize oral hygiene and pain relief when the oral source is unconfirmed.
    • Defer definitive dental treatment, including extractions, until IE and complications resolve.
