Heparin-induced thrombocytopenia (HIT) type II is typically characterized by a decrease in platelet count to values between 20 and 120 × 109/L or a platelet count fall of greater than 50 %. We report on a patient who developed a HIT syndrome, thrombosis of the vena cava, and fulminant pulmonary embolism during heparin treatment after cesarean section, without a significant decrease in platelet count. Lepirudin anticoagulation and ecarin clotting time (ECT) monitoring were used successfully during cardiopulmonary bypass.
