A 58-year-old man with medical history of thrombocytopenia was admitted to an outside hospital for a 6-day history of worsening dyspnoea requiring mechanical ventilator support. He was transferred to our institution for extracorporeal membrane oxygenation (ECMO) given his refractory hypoxaemia. On arrival, H1N1 influenza virus was confirmed and all measures to improve oxygenation were ineffective. Thus, the decision was made to start venovenous (VV)-ECMO. Although a low baseline platelet count was recognised (60–70×109/L), a sudden further decrease occurred (30×109/L) and platelet transfusion was initiated. A substantial increase in the pressure across the ECMO oxygenator was identified, and the diagnosis of type II heparin-induced thrombocytopenia was suspected and confirmed. Heparin was discontinued, the oxygenator was exchanged and argatroban w...
