title: [Management of intracranial dural arteriovenous fistulas with cortical venous drainage].
abstract: OBJECTIVE
  Intracranial dural arteriovenous fistulas (DAVF) with cortical venous drainage are vascular malformations with high hemorrhagic risk. Their treatment may be complex and requires a multidisciplinary approach.
  
  
  METHODS
  We retrospectively report 38 observations of dural arteriovenous fistulas with cortical venous drainage from 1990 to 2001. There were 28 men and 10 women with a mean age of 57 years. Hemorrhage revealed the malformation in 24 cases (63%). The other patients had headache, neurological deficit, seizure or pulsating mass of the scalp. One patient was asymptomatic. All the patients had DAVF with cortical venous drainage and decision of treatment was in each case multidisciplinary.
  
  
  RESULTS
  Of the 38 patients, seven had no treatment for the following reasons: spontaneous occlusion of the malformation after hemorrhage, refusal of treatment, or poor neurological status at the admission. Thirty-one patients were treated and complete exclusion of the fistula was obtained in 30 cases. Endovascular occlusion of the fistula was performed in 14 patients, surgical clipping of the origin of the draining vein in 12 and combined treatment (surgical clipping after embolization of feeding arteries) in four. One patient had an untreated fistula despite several procedures.
  
  
  CONCLUSIONS
  Complete exclusion of these malformations is mandatory because of the potential risk of hemorrhagic complications. The best treatment is the occlusion of the origin of the draining vein (endovascular or surgical) and requires multidisciplinary discussion.
