Thromboembolic prophylaxis with danaparoïd (Orgaran) in a high-thrombosis-risk pregnant woman with a history of heparin-induced thrombocytopenia (HIT) and Widal's disease.

There is no consensus concerning thromboembolic prophylaxis in high-risk pregnant women with a previous history of heparin-induced thrombocytopenia. An alternative anticoagulant therapy is danaparoïd, whereas unfractioned and low-molecular-weight heparin therapy is contraindicated. We report a case of successful thrombosis prophylaxis using danaparoïd in a high-thrombosis-risk pregnant woman with a history of heparin-induced thrombocytopenia during a previous pregnancy and Widal's disease.
