Abstract
Previous exposition to heparin and protamine in patients undergoing cardiopulmonary bypass and postoperative therapeuticanticoagulation with LMWH may lead to the development of heparin-induced thrombocytopenia (HIT) and/or protamine-inducedthrombocytopenia(PIT).*iscasedealswith arareclinicalpresentationofcirculatingIgGantibodies againstheparin/plateletfactor4complexesandheparin/protaminecomplexesaftercardiacsurgery.Ensuingpurpuraandskinnecrosis(blisters)at the injection sites of LMWH and clinical symptoms improved rapidly after replacement of LMWH by an alternative anti-coagulant.*eaimofthisreportistodrawattentiontotheseveraldifferentclinicalmanifestationsofheparin-and/orprotamine-induced thrombocytopenia and shows a possible course of treatment and recovery.
