[edit] Discussion of Developmental venous anomaly

  • Developmental venous anomalies (DVA) are cerebral vascular malformations that consist of dilated intramedullary veins converging into a large draining vein that reaches either the superficial or the deep system in an area in which there is an absence of normal draining veins.
  • DVAs are known to be associated with other developmental vascular anomalies, especially cavernous malformations.
