Lepirudin anticoagulation for heparin-induced thrombocytopenia.

Lepirudin is indicated for anticoagulation in patients with heparin-induced thrombocytopenia (HIT). We describe 2 cases of HIT and thrombosis in children with heart disease, including one that required extracorporeal membrane oxygenation. Lepirudin, dosed in the recommended adult weight--based fashion, was an effective antithrombotic agent in pediatric patients with HIT.
