Occlusion of a large pulmonary arteriovenous malformation in a paediatric patient using multiple vascular plugs.

Pulmonary arteriovenous malformations (PAVMs) are caused by an abnormal vascular communication between a pulmonary artery and vein. They are usually congenital in nature and are associated with considerable morbidity and mortality if left untreated. Transcatheter techniques are the favoured option for PAVM occlusion in children, and large lesions can have multiple feeder vessels that may not be appreciated until selective angiography is performed. We describe the successful occlusion of a large PAVM in a paediatric patient using multiple Amplatzer vascular plugs.
