Developmental venous anomaly

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

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.

Developmental venous anomalies are known to be associated with other developmental vascular anomalies, especially cavernous malformations.
