Three patients with vertebral arteriovenous fistulae are described. Transarterial embolization by microcoils and balloons was used in each case and the fistula was completely occluded in one case immediately after embolization. Another two cases with partial obliteration of the fistula were followed and showed complete occlusion of the fistula after a one year follow-up.
After embolization of the fistula, each patient improved in clinical signs and symptoms and showed no complications. Transarterial embolization for vertebral arteriovenous fistula is a safe and effective treatment.
