Radiosurgery of cerebral arteriovenous malformations with a linear accelerator: preliminary report.

The authors present the results obtained in seven patients with arteriovenous malformations treated with radiosurgery on a linear accelerator. In four patients obliteration of the malformation was obtained after one year. Two of the patients had a transient period of acute brain oedema surrounding the radionecrotic nidus with neurological signs. The present position of radiosurgery in the treatment of arteriovenous malformations is discussed
