'Early' post-cardiotomy chylopericardium and the imaging value of magnetic resonance thoracic-ductography.

Isolated chylopericardium is a rare postoperative complication after cardiac surgery. A delay in diagnosis or an inappropriate management can lead to serious consequences. The treatment, which may either be conservative or surgical, is controversial and it depends on the duration and volume of effusion. We report a case of chylopericardium after atrial septal defect repair in a young woman. The patient was treated initially with total parenteral nutrition for 10 days. After drainage diminished, low fat diet containing medium chain triglyceride was instituted. Postoperatively, the role of magnetic resonance thoracic ductography was important for the assessment of the treatment strategy.
