Abstract
Seven cases of dural arteriovenous malformation are reported with analysis of the symptoms, hemodynamics, treatment and follow-up results.
The present disease is thought to be progressive and should be definitely distinguished from the intracerebral AVM and traumatic arteriovenous fistula since the hemodynamics of arteriovenous shunt showed extensive and dynamic changes with the lapse of time as observed from the results of long-term follow-up studies.
The best treatment is to primarily block arteriovenous shunt at the dura and tent as much as possible.
