Cerebral arteriovenous malformation

Arteriovenous malformations of the brain are tortuous, morphologically abnormal vascular channels between arteries and veins that lack an intervening capillary network, allowing high-pressure arterial blood from feeding arteries to shunt directly into the venous outflow system. These vascular malformations occur in approximately 15 per 100,000 persons and are a leading cause of hemorrhagic stroke in young adults and children (summary by Nikolaev et al., 2018).
