A case of acute purulent pericarditis due to MRSA treated with daily pericardial lavage for one month followed by pericardial fenestration.

UNLABELLED

Acute purulent pericarditis is a rare infection in developed countries. We herein report a case with diabetic nephropathy under maintenance hemodialysis who suffered from acute purulent pericarditis caused by methicillin-resistant (MRSA). The treatment of purulent pericarditis mainly involves rapid administration of appropriate antibiotics and drainage. However, in this case, the patient was unresponsive to vancomycin and performing early surgical intervention was challenging due to highly pathogenic MRSA. Therefore, we performed pericardial fenestration in the chronic phase to suppress the risk of fatal secondary infections after daily irrigation for one month to reduce bacterial load mechanically.

LEARNING OBJECTIVE

In a case of purulent pericarditis caused by highly pathogenic methicillin-resistant resistant to antibiotics and resulting in constrictive pericarditis, it was possible to perform pericardial fenestration in the chronic phase, while mitigating the risk of fatal secondary infections, by controlling the inflammation through daily irrigation for a long time to reduce the bacterial load mechanically.
