Coil Embolization of a Neonatal Pulmonary Arteriovenous Malformation

Pulmonary arteriovenous malformation (PAVM), as a part of Osler-Weber-Rendu Syndrome, in the neonate, is a rare hereditary vascular malformation. Large intrapulmonary right-to-left shunting, causing hypoxaemia and cyanosis, can be a life-threatening condition. Repeated transcatheter coil embolization procedures proved to be a favorable strategy to improve systemic arterial oxygen saturation, with a good outcome in a newborn child. While the radiation dose was high, the use of this amount of radiation was felt to be justified and its effects considered tolerable in the treatment of this patient's serious malformation.
