Isolated chylopericardium, a rare condition with milky fluid in the pericardial sac, was diagnosed in a young male. Surgical intervention involving thoracic duct ligation and pericardial window creation proved effective for this challenging lymphatic disorder.

Area of Science:

  • Cardiology
  • Thoracic Surgery
  • Medical Diagnostics

Background:

  • Pericardial effusion, the accumulation of fluid around the heart, can have various causes.
  • Chylopericardium, characterized by milky, chylous fluid, is a rare form of pericardial effusion.
  • Isolated chylopericardium, without other systemic lymphatic abnormalities, presents diagnostic and therapeutic challenges.

Observation:

  • A 25-year-old male presented with asymptomatic pericardial effusion detected during a routine medical evaluation.
  • Pericardiocentesis yielded 1200 ml of milky-white fluid, confirmed biochemically as chylous.
  • The patient was diagnosed with isolated chylopericardium after excluding other potential causes.

Findings:

  • Despite initial diagnosis, the patient experienced recurrent episodes of chylopericardium.

  • Surgical management, including thoracotomy with thoracic duct ligation and pericardial window creation, was performed.
  • The etiology and pathogenesis of true isolated chylopericardium remain largely unknown, with a postulated primary abnormality in thoracic lymphatic valves.

    • Implications:

    • This case highlights the rarity and diagnostic difficulty of isolated chylopericardium.
    • Surgical intervention, specifically thoracic duct ligation, is considered the most effective treatment.
    • Further research into the underlying mechanisms of lymphatic valve dysfunction is warranted to understand and potentially prevent this condition.
