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) rel ated to cerebral arteriovenous malformations cerebral arteriovenous malform ations can be correlated with the anatomy and the angioarchitecture of the cerebral arteriovenous malformations. The most dramatic data were the bipol ar-like correlations between hemorrhage and seizures: each parameter correl ated positively with hemorrhage was correlated negatively with seizures and vice verse. These data seem to show that cerebral arteriovenous malformati ons causing seizures have a low risk of hemorrhage, and cerebral arterioven ous malformations with a high hemorrhage risk have a low risk of seizures ( excepting with an hematoma). For headaches and progressive neurological deficits anatomoclinical correla tions can improve knowledge of their pathophysiology.
