Heparin-induced thrombosis with a normal platelet count.
Heparin is commonly used in the intensive care unit for preventing and treating thromboembolic disease. One of its more significant complications is heparin-induced thrombocytopenia (HIT), an immune-mediated disorder which can provoke an extreme prothrombotic state. We describe an unusual presentation of HIT, where thrombocytopenia was absent.
