Hereditary hemorrhagic teleangectasia: Interventional treatment of pulmonary arteriovenous malformations in the pediatric population

Abstract 

Pulmonary arteriovenous malformations are present in a large proportion of children with hereditary hemorrhagic teleangectasia. The major risk caused by such a malformation is paradoxical embolism and cerebral stroke. Currently, only feeding arteries of 3 mm in diameter or more are considered appropriate for embolization. The purpose of this review is to describe the unique features of hereditary hemorrhagic teleangectasia in the pediatric population and to report our cases of embolization of arteriovenous malformations in such patients. We believe that feeding arteries <3 mm in size should be embolized in the pediatric age group.
