title: Balloon protection of the Labbé vein during transarterial embolization of a dural arterio-venous fistula.
abstract: BACKGROUND
  Endovascular treatment of type III dural arterio-venous fistulas can be challenging if the fistulous point is close to a functionally important cortical vein.
  
  
  METHODS
  A technique is described for temporary balloon protection of the vein of Labbé during transarterial Onyx embolization of a type III dural arterio-venous fistula. One illustrative case is presented. Careful anatomic consideration of the concerned venous segment (at the insertion point into the lateral sinus) and the choice of balloon minimized the risk of venous rupture.
  
  
  RESULTS
  Using this method, satisfactory progression of Onyx was obtained within the arterio-venous shunt while preserving the patency of the Labbé vein.
  
  
  CONCLUSIONS
  Temporary balloon protection of the Labbé vein is a feasible option to preserve its patency during embolization of dural arterio-venous fistulas. To the authors' knowledge, this is the first report on the use of temporary balloon protection of a cortical vein.
