Pediatric heparin-induced thrombocytopenia: management with Danaparoid (Orgaran)

Heparin-induced thrombocytopenia is a rare and serious complication of anticoagulation therapy. There remains a paucity of information pertaining to alternative anticoagulation strategies for use during cardiopulmonary bypass concomitant with heparin-induced thrombocytopenia, especially in children. We report the successful treatment of heparin-induced thrombocytopenia and subsequent hemorrhagic complications postoperatively in a 2-year-old child with Danaparoid (orgaran). Emergent conduit revision with cardiopulmonary bypass was required for a thrombosed systemic-venous to pulmonary-arterial connection (completion modified Fontan procedure). Required doses of Danaparoid were consistently twofold that previously reported for adults.
