[Extracorporeal circulation with danaparoid sodium for valve replacement in thrombocytopenia induced by type II heparin]

Abstract

A type II heparin-induced thrombocytopenia (HIT) was diagnosed in a 64-year-old woman at day 20 of intravenous unfractionated heparin (UFH) therapy, given after myocardial infarction treated by angioplasty and intracoronary stent. The infarction was complicated by a mitral insufficiency that led to a mitral valve replacement. Cardiopulmonary bypass was successfully performed with sodium danaparoid (Orgaran), as an alternative to UFH, without thrombotic or haemorrhagic complications and the follow-up was uneventful.
