[Purulent pericarditis in a patient with diabetes mellitus treated by percutaneous pericardiocentesis]. / Péricardite purulente chez un patient diabétique traitée par drainage péricardique percutané.

Purulent pericarditis seldom occurs in Western countries, yet its mortality rate remains high between 20 and 35 % despite early treatment. We report the case of a 43-year-old patient admitted in the intensive cardiologic care unit with a pre-tamponade, requiring an immediate percutaneous pericardiocentesis allowing the drainage of a purulent effusion. Evolution with antibiotic therapy adapted according to the bacteriological findings was favorable and 3-months follow-up shows a near complete regression of the effusion. This case recalls us this rare diagnosis entity and illustrates the possibility of a mere percutaneous pericardial drainage with the condition of a strict medical surveillance.
