Interventional occlusion of a large pulmonary arteriovenous malformation with an Amplatzer septal occluder.

Interventional occlusion of pulmonary arteriovenous malformations with large feeding arteries may be associated with an increased risk of device embolization. In a 40-year-old patient with a solitary pulmonary arteriovenous malformation one large feeding artery was successfully closed by means of an Amplatzer septal occluder and detachable coils. The use of an Amplatzer septal occluder should be considered as an alternative therapeutic option in cases of huge pulmonary arteriovenous malformation to reduce the risk of device embolization.
