Pregnancy associated with lupus anticoagulant and heparin induced thrombocytopenia: management with a low molecular weight heparinoid.

The management of pregnant patients with coagulopathies and heparin induced thrombocytopenia is difficult and poorly defined. We report the case of a patient who was treated with a low molecular weight heparinoid. The treatment was complicated by the delayed occurrence of thrombocytopenia and a thrombotic event. This is the first report of thrombocytopenia caused by heparinoid. It is possible that this complication could have been avoided by a shorter duration of treatment with heparinoid and the use of Vitamin K antagonists during the second trimester of pregnancy.
