Biology of Cerebral Arteriovenous Malformations and Prognosis of Cerebral Arteriovenous Malformations
Biology of Cerebral Arteriovenous Malformations and Prognosis of Cerebral Arteriovenous Malformations
The cerebral arteriovenous malformations correspond to the formation of an entanglement of
 morphologically abnormal vessels called nidus, which shunt the blood circulation directly
 from the arterial circulation to the venous circulation.

 The cerebral arteriovenous malformations are an important cause of hemorrhagic stroke.

 The hypothesis is that cerebral haemorrhage associated with a cerebral arteriovenous
 malformations would come from peri-nidal micro-vessels, in connection with infiltration of
 leucocytes and / or defective maintenance of microvascular integrity by platelets.
