Abstract
The risk for immune-mediated heparin-induced thrombocytopenia (HIT) in neurologic patients receiving unfractionated heparin (UFH) is not known. In a prospective study of 200 patients, the authors found a 2.5% rate of HIT and a 2% rate of HIT-associated thromboses, suggesting that neurologic patients treated with UFH are at considerable risk for development of HIT and its complications. Prevalence of heparin-induced antibodies was 20.5% and was dependent on heparin dose. It was higher in cerebrovascular than in noncerebrovascular (29.4% versus 11.2%, p < 0.01) patients.
