Use of Low-Molecular-Weight Heparin for Right Atrial Thrombus Following Extracorporeal Membrane Oxygenation in Neonates after Surgical Repair of Congenital Diaphragmatic Hernia: A Case Report and Review of the Literature

Some critically ill neonates with congenital diaphragmatic hernia (CDH) require extracorporeal membrane oxygenation (ECMO) during the perioperative period. Neonates on ECMO face a significantly increased risk of thrombotic events. Thrombosis management varies across centers and may include anticoagulation, thrombolysis, or thrombectomy. We present our experience using low molecular weight heparin (LMWH) to treat a right atrial thrombus (RAT) following ECMO in a neonate with CDH.
