Postpericardiotomy syndrome as a cause of recurrent pleural effusion

The postpericardiotomy syndrome occurs frequently after cardiac surgery, and shows a strong tendency to recur. It is characterized by febrile illness with an elevated erythrocyte sedimentation rate, leucocytosis, and symptoms of pulmonary and pleuro-pericardial inflammation. Pleural effusion is a common manifestation of this syndrome, and is usually left-sided. We describe a patient who shows a periodic left-sided pleural effusion with an interval of 5 to 6 weeks 18 months after cardiac surgery. This is the first description of a 'cyclic' pleural effusion due to the postpericardiotomy syndrome. On the basis of this case report and the literature, we discuss the pathogenesis, therapy and clinical outcome of this syndrome.
