RESUMEN

A 50-year-old man was admitted to our hospital due to chest pain. He had a history of chronic pancreatitis associated with a pancreatic pseudocyst. Coronary angiography revealed stenotic lesions in left main trunk and right coronary artery coronary artery bypass grafting (RITA-LAD, LITA-OM, SVG-#4PD) were performed. The postoperative course was uneventful without any complications, and he was discharged on the 9th day after surgery. A week later, fatigue and dyspnea appeared. Echocardiography showed a large mount of pericardial fluid and echo-guided pericardiocentesis was performed. One week after the procedure the pericardial fluid reaccumulated. Pericardial drainage resulted in continuous drainage of pericardial fluid. A 7 French plastic stent was placed in the pancreatic pseudocyst, which decompressed the pancreatic pseudocyst, which led to the disappearance of pericardial effusion accumulation. The possible relation between a recurrent pericardial fluid accumulation and a pancreatic pseudocyst was suspected.
