title: [Thrombocytopenia after cardiac surgery due to anti-platelet allo-immunization. Apropos of a case].
abstract: Thrombocytopaenia is rare after cardiac surgery but carries a very high risk of bleeding and thrombotic complications. It is generally due to heparinisation but may be secondary to the surgical procedure itself (cardiopulmonary bypass, sepsis, platelet consumption by the prosthesis), or associated factors (massive blood transfusion, drug reaction, rare antiplatelet allo-immunisation). One case of post-transfusion thrombocytopenia with antiplatelet anti-HPA-la allo-antibodies with a favourable outcome with high dose polyvalent gammaglobulins is reported. The authors describe the diagnostic and therapeutic approaches to this problem.
