Through an anatomoclinical classification for arteriovenous malformations

This brief study tends to point out that each clinical symptom (hemorrhage, seizures or epilepsy, headaches and progressive neurological deficits) related to cerebral arteriovenous malformations cerebral arteriovenous malformations can be correlated with the anatomy and the angioarchitecture of the cerebral arteriovenous malformations. The most dramatic data were the bipolar-like correlations between hemorrhage and seizures: each parameter correlated positively with hemorrhage was correlated negatively with seizures and vice verse. These data seem to show that cerebral arteriovenous malformations causing seizures have a low risk of hemorrhage, and cerebral arteriovenous malformations with a high hemorrhage risk have a low risk of seizures (excepting with an hematoma). For headaches and progressive neurological deficits anatomoclinical correlations can improve knowledge of their pathophysiology.
