The putative role of the venous system in the genesis of vascular malformations
Neurosurgical Focus, 11/10/2009
|
Aboian MS et al. – The authors review the clinical and experimental evidence linking the venous system and its anomalies to the genesis of various intracranial vascular malformations, including dural arteriovenous fistulas, cavernous malformations, parenchymal ... malformations, and capillary telangiectasia. They also describe the potential significance of different associations of these vascular anomalies.

An intrathoracic arteriovenous malformation discovered as an extremely uncommon reason of neonatal congestive cardiac failure
Cardiology in the Young, 10/23/2009
|
Hofmann SR et al. – Congenital arteriovenous malformations are rare causes of congestive cardiac failure in neonates. The most common sites are in the head and liver ... malformation of the vein of Galen, and other arteriovenous malformations in different locations which produce high flow can present early. The authors describe here the first case, to the best of their knowledge, of prenatal detection of an intrathoracic arteriovenous malformation producing neonatal
