Successful treatment of a patient with purulent pericarditis by daily intrapericardial washouts.

Abstract

Purulent pericarditis in adults is rare, but once it develops, it carries a high mortality rate. Adequate pericardial drainage and proper antibiotic treatment are essential in the successful management of purulent effusions, for which percutaneous catheter drainage is the most commonly performed technique. We herein report the case of a 75-year-old woman with purulent pericarditis attributable to methicillin-resistant Staphylococcus aureus. Although percutaneous pericardial drainage by catheter was used, the drainage was insufficient because of hyperviscous effusion. We performed surgical subxiphoid pericardial drainage, and a piece of a purulent stone was found in the pericardial cavity with purulent effusion. Additionally, daily intrapericardial washouts with physiologic saline alone were used as adjunct therapy. Five weeks later, the patient had a decreasing inflammatory reaction and symptom relief. She was discharged with no complications such as constrictive pericarditis.
