Arteriovenous malformation drained into a developmental venous anomaly: a case report and up-dated literature review.

CONCLUSION: The co-occurrence of a DVA and an AVM is rare but has a higher bleeding risk than AVM alone (69% vs 38%) and must consequently be suspected when a DVA is revealed by a haemorrhage, in the absence of associated cavernoma. These mixed malformations represent a therapeutic challenge which has to be tailored to the venous anatomy and to the malformation Spetzler-Martin grade. DVA permeability should be preserved to avoid deleterious venous infarction.
