title: An analysis of the correlation between angiographic and clinical findings in cerebral arteriovenous malformations.
abstract: One hundred and sixty-seven cases of cerebral arteriovenous malformations (AVMs) confirmed by digital subtract angiography (DSA) and surgery were analyzed to find the correlation between clinical and angiographic findings with regard to sex, age, size of angioma, and number of drainage veins and feeding arteries. Statistical analysis showed that the risk of hemorrhage was highest in small AVMs with only one drainage vein, and decreased with increases of volume and number of AVMs. Statistics also demonstrated that small AVMs usually have one drainage vein and so have a high risk of hemorrhage.
