[Successful use of a heparinoid (danaparoid sodium) for heparin-induced thrombocytopenia type II in aortic valve reoperation].

The 29-year-old, heroin-addicted patient received an aortic valve prothesis (SJM) 10 years ago because of aortic valve stenosis III. One year after surgical treatment he refused to take Phenprocoumon and thus received no anticoagulation for 9 years. The patient was hospitalized due to cardial decompensation and thrombosis of the aortic valve prothesis was diagnosed. Under heparinization, he developed heparin-induced thrombocytopenia type II, which disappeared after changing the medication to Danaparoid-Sodium. In order to avoid any further heparin exposure, we also carried out the surgical replacement of the aortic valve prothesis under anticoagulation with Danaparoid-Sodium.
