[Heparin-induced thrombopenia: rapid regression of thrombopenia and thrombosis after plasma exchange. Case report]

Heparin-induced thrombocytopenia with thrombosis is a rare but severe adverse reaction to heparin therapy, whose management is difficult. After heparin withdrawal, the initiation of an alternative anticoagulant therapy, such as recombinant hirudin or danaparoid, is strongly recommended before vitamin K antagonists are effective. Several reports of the efficacity of plasma exchanges in patients with life-threatening thrombosis have been made.

We report on a patient with severe aortic thrombosis related to heparin therapy in whom a unique plasma exchange resulted in both dramatic improvement in the platelet count and marked reduction of the thrombosis.

This case provides further evidence that plasma exchanges can be useful in the management of heparin-induced thrombocytopenia with thrombosis. They are rapidly efficient and can be used before heparin alternative treatment is effective.
