[Hypertriglyceridemic pancreatitis and cardiac tamponade in a 26-year-old woman].

A 26-year-old woman with type 2 diabetes mellitus and discontinued intensive conventional insulin therapy was admitted to the authors' hospital with acute upper abdominal pain. Severe hypertriglyceridemia and acute pancreatitis were diagnosed. Treatment included insulin administration and plasmapheresis. On day 3, the patient developed sudden haemodynamic instability and in-hospital cardiopulmonary arrest. Focused echocardiography showed pericardial effusion with right ventricular collapse. Pericardiocentesis was performed, leading to a return of spontaneous circulation.
