Suppression of fluid accumulation following pericardial inflammation in a patient with primary chylopericardium.

The patient was a 50-year-old woman with primary chylopericardium. Triglyceride rich chyloid fluid was continuously drained from the pericardial space through an indwelling catheter. A surgical procedure was scheduled since a medium chain triglyceride diet was insufficient to control the fluid accumulation. Before the operation, inflammatory signs were apparent around the indwelling catheter and the catheter was removed immediately. The inflammation was easily treated with antibiotics, and the pericardial effusion no longer accumulated during a follow-up period of 10 months. The inflammatory process may have caused fibrin production and tissue adhesion in the pericardial cavity, and these might have prevented an accumulation of chyloid fluid and occluded the connection between the thoracic duct and the pericardial cavity.
