White clot syndrome associated with renal failure.
In a minority of patients, heparin administration is associated with thrombocytopenia and this thrombocytopenia may be associated with thromboembolic events. Heparin-associated thromboembolism is described as heparin-associated thrombocytopenia and thrombosis or white clot syndrome. White clot syndrome is caused by antibodies to a heparin-platelet membrane complex. The diagnosis carries a high mortality and morbidity from limb thromboembolism. Treatment includes discontinuation of heparin, use of alternate anticoagulants, and aggressive treatment of thromboses. A case in which acute renal failure occurred in the setting of heparin treatment and thrombocytopenia is described, and evidence that renal failure was a result of white clot syndrome is provided.
