title: Transvenous balloon-assisted transarterial Onyx embolization of transverse-sigmoid dural arteriovenous malformation.
abstract: BACKGROUND
  Endovascular treatment of dural arteriovenous malformation is challenging especially if the related dural venous sinus is patent and might be usable for normal venous drainage.
  
  
  METHODS
  A new particular venous balloon remodeling technique was described in the treatment of transverse-sigmoid dural arteriovenous malformation by using transarterial Onyx. The goal was obliteration of the malformation with preservation of the dural sinus. Two illustrative cases with 6-month follow-up result were narrated.
  
  
  RESULTS
  The penetration of Onyx in the dural arterial feeders was well achieved. Obliteration of the malformation with preservation of the dural sinus was finally demonstrated.
  
  
  CONCLUSIONS
  Transvenous balloon assistance is a useful and feasible technique in the treatment of dural arteriovenous malformation when sinus preservation is in concern.
