Patient with rare disease

The purpose of our study is to demonstrate by blood samples in situ in the vascular lesion (performed during any cerebral catheterization for an embolization of arteriovenous malformation) the existence of angiogenic growth factors and inflammatory factors that would confirm the decompensation of venous ischemia.

Main Inclusion Criteria:

• Presenting a DVA requiring hyperselective catheterization
• Having sign an informed consent form

Exclusion Criteria:

• Presenting a contraindication to the realization of hyperselective cathterism
