HIT affects 1 in 5000 hospitalized patients and paradoxically results in a prothrombotic state and usually does not induce bleeding.4 Thromboembolic phenomena are seen in half of the patients with confirmed HIT.4 The mortality rate is around 5% and 10%.6 In our patient with HIT, the diagnosis of venous thromboembolism preceded thrombocytopenia, which is not uncommon. In a series of 408 patients of HIT with thrombosis, 33.5% of patients developed thrombosis before the decrease in platelet counts.7
