Diagnosis and endovascular treatment of pediatric spinal arteriovenous shunts

Abstract

Spinal arteriovenous shunts (SAVSs) are rarely diagnosed in infants and children, but they are important clinically because morbidity can be significant. Although these lesions do not form a distinct pathologic group separate from the SAVSs seen in older patients, experience with these malformations in the pediatric population has led to the identification of several important features that are characteristic of this group of SAVSs. Association with genetic abnormalities, heritable (hereditary hemorrhagic telangiectasia) and nonheritable somatic (spinal arteriovenous metameric syndrome or Cobb syndrome), is relatively common and likely underrecognized. Male predominance is more pronounced than in the adult population. Hemorrhagic presentation is more frequent than in adults, except in extremely young children. The natural history seems to be better than previously thought, with early rehemorrhage uncommon. Despite early presentation and severe symptoms, these lesions are frequently amenable to endovascular treatment, often with anatomic cure achieved and with improvement or stabilization of symptoms after partial targeted treatment.
