Developmental Venous Anomalies

Developmental venous anomalies are benign developmental anomalies of the cerebral venous system that rarely hemorrhage [9]. They comprise numerous small veins that drain in a centripetal pattern into a large venous trunk, analogous to the spokes of a bicycle wheel. The venous trunk subsequently drains into a superficial vein that connects to a dural sinus. These lesions are thought to be primitive venous elements that fail to regress during fetal development and so function like normal subcortical veins. Consequently, surgical resection is not indicated. Histologically, DVAs comprise normal, thin-walled venous structures. Vessel wall hyalinization may occur; this, however, is not associated with a worse prognosis. Developmental venous anomalies may be associated with cavernous malformations.
