Why the study?
COVID-19 causes coagulation abnormalities for which heparin is advised, but heparin-induced thrombocytopenia is a concerning complication.
This case highlights the importance of monitoring for heparin-induced thrombocytopenia in post-cardiac surgery patients receiving heparin for COVID-19 associated coagulopathy.
Background : Coronavirus infectious disease 2019 (COVID-19), which evolved to a global pandemic issue leads to coagulation system abnormalities and low molecular heparin or unfractionated heparin is advised. Heparin-induced thrombocytopenia (HIT) is one of the most worried complications of heparin exposure.Case Presentation: In this case report, we presented a 75 year- old male patient with suspicious COVID-19 infection who admitted to our intensive care unit one month after cardiac surgery. On admission due to increased D-dimer level and history of CABG, he was started to LMWH (enoxaparin) 0.5 mg/kg twice daily yet HIT occurred and enoxaparin was held. Fondaparinux was started to decrease the thrombosis risk.Conclusion: In the era of COVID-19, the management of coagulopathy is important while HIT should be mind in every patient after the preliminary heparin treatment.
