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.
