Successful Conservative Treatment of Chylopericardium after Open-Heart Surgery: A Case Report

Chylopericardium is a rare complication following cardiac surgery. The incidence of this pathological condition is very low and mainly attributed to lymphatic injuries to the thymus or anterior mediastinum, thoracic duct injuries, or extensive posterior pericardial dissection with the possible interruption of major cardiac lymph channels. A 62-year-old man was admitted to the cardiovascular surgery department for coronary bypass surgery, and the surgical procedure was performed 3 days later. Revision surgery was performed, because of the drainage associated with bleeding. In the post-revision days, the amount of serous drainage increased, and then chylous drainage occurred. After conservative treatment, the drainage of the chylous features decreased and eventually disappeared. The patient was discharged without any problem. At 6 months' follow-up, the patient was doing well with a normal left ventricular function and without effusion.
