Arteriovenous fistulae may be single or multiple. Clinical signs emerge depending on the size of the fistulae and amount of shunt. Due to the advancements in transcatheter devices and increased experience render enable the fistula embolisation procedure as an alternative to surgical treatment. Extracorporeal membrane oxygenation is used to support the patient haemodynamically and respirationally in cases of treatment-resistant, severe and revocable cardiac or pulmonary sufficiency. This paper presents an infant patient with pulmonary arteriovenous malformation, who had haemodynamic instability due to severe hypoxia and received successful transcatheter fistula embolisation via extracorporeal membrane oxygenation under emergency conditions.Cardiac and cardiovascular systemsPediatricsJournal Article1467-1107849225900001Q45847
