Argatroban for an alternative anticoagulant in HIT during ECMO

Abstract

Background: Extracorporeal membrane oxygenation (ECMO) have become more frequently used in daily ICU practice, heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication while on extracorporeal membrane oxygenation (ECMO). HIT confirmation directly impacts on anticoagulant strategy requiring no delay unfractionated heparin discontinuation to be replaced by alternative systemic anticoagulant treatment. Case presentation: We report two clinical cases of HIT occurring during ECMO in various settings with subsequent recovery with argatroban and provide literature review to help physicians treat HIT during ECMO in clinical daily practice. Conclusions: HIT during ECMO is uncommon, and despite the absence of recommendation, argatroban seems to be an appropriate and safe therapeutic option. Finally, there are not enough arguments favouring routine circuit change in the event of HIT during ECMO.
