Targeted neonatal echocardiography-guided therapy pre-embolisation for congenital hepatic vascular malformation: inhaled nitric oxide to prevent paradoxical embolisation to the systemic circulation

Abstract

AbstractArteriovenous malformations may present with significant haemodynamic compromise in the neonatal period, typically with high output cardiac failure that may be accompanied by hypoxia and right ventricular dysfunction. Targeted neonatal echocardiography performed by trained neonatologists provides an enhanced physiology-based approach that can guide treatment and minimise complications. We present a case of a large hepatic vascular malformation whose therapy was guided by targeted neonatal echocardiography to prevent paradoxical embolisation of procedural glue to the systemic circulation.
