Interventional treatment by neuroradiological embolisation of cerebral
arteriovenous angiomas has become an alternative to surgical exstirpa
tion especially in problematic localisations and large-size malformati
ons. Clinical results showing a marked reduction in attacks and recurr
ent haemorrhages, evident from a three-year report on 17 patients, con
firm the value of the method even in case of only subtotal occlusion o
f the malformation.
