title: Heparin-induced thrombocytopenia associated with pulmonary embolism.
abstract: Type II heparin-induced thrombocytopenia (HIT) is a potentially severe adverse effect of heparin treatment triggered by an immune response. Although most cases occur in patients receiving unfractioned heparin, HIT can also arise after low-molecular-weight heparin (LMWH). We report a case of HIT in a postoperative orthopedic 75-year-old woman in treatment with LMWH (nadroparin) complicated by pulmonary embolism and treated successfully with recombinant hirudin. Early recognition and proper treatment are fundamental for the management of this life-threatening disorder.
