Arteriovenous malformations of the dura mater.

The presentation, angiographic findings, and treatment of eight dural arteriovenous malformations is reviewed. The majority presented as intracranial hemorrhage, one of which was an intracerebral hemorrhage, and an aneurysm was found in conjunction with two of the eight. Preoperative embolization of one of the malformations was used with an excellent result. Five of eight were treated surgically with a good outcome. Patient outcome, whether surgically treated or not, was good in all cases though follow-up is a maximum of 3 years, except for one case of 23 years.
