INTRODUCTION: 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. CONCLUSION: Transvenous balloon assistance is a useful and feasible technique in the treatment of dural arteriovenous malformation when sinus preservation is in concern.
