Angiology
-
The authors describe a patient with stroke, treated with heparin for unstable angina, whose clinical features mimicked those of thrombotic thrombocytopenic purpura (TTP). His condition eventually proved to be caused by heparin-induced thrombocytopenia (HIT), complicated by thrombosis (HITT). ⋯ Heparin treatment has to be stopped immediately if HITT is diagnosed. First-choice antithrombotic treatment in HITT patients is danaparoid.
