Patterns of practice for management of cerebral venous thrombosis in Canada are unknown. We surveyed Canadian neurologists and hematologists regarding anticoagulation in cerebral venous thrombosis. The response rate was 28%, with 27 neurologists and 20 hematologists responding. We found that choice of first-line initial anticoagulation differed significantly between neurologists and hematologists, with 89% of neurologists favouring unfractionated heparin and hematologists’ preference split between unfractionated heparin (50%) and low-molecular-weight heparin (50%). Differences in patterns of practice likely reflect clinical equipoise.
