Since the introduction of antibiotics into clinical practice, purulent pericarditis has become a rare disease. The major complication of the standard management for this condition is constrictive pericarditis. We report two cases of purulent pericarditis in which intrapericardial fibrinolysis was performed in order to minimize this complication. The first case was a 38-year-old man admitted to our intensive care unit (ICU) for management of constrictive pericarditis complicating purulent pericarditis diagnosed 17 days previously. The patient was treated with four intrapericardial injections of streptokinase (250,000 IU each). Fluid drainage and cardiac output were improved. No change in clotting parameters was noted. Pericardiectomy and esophagectomy were then performed for a diagnosis of esophageal neoplasm. The postoperative course was uneventful. The second case was a 16-year-old boy admitted with loss of consciousness due to cardiac tamponade. Percutaneous pericardiocentesis drained 900 ml of cloudy fluid. Two intrapericardial injections were performed (day 1 and day 5) without any complication. Pericardial drainage was withdrawn on day 13 and the patient was discharged from ICU on the same day. Six months later, there was no evidence of constrictive pericarditis. Intrapericardial fibrinolysis appears to be safe and effective when prescribed rapidly in the course of purulent pericarditis.
