We present here a case of a posttraumatic vertebral AVF previously treated (unsuccessfully) by ligation of the vertebral artery proximal and distal to the site of the fistula. Unusual transspinal interarterial collateral blood flow from the nonaffected left vertebral artery toward the affected right vertebral artery resulted in a neurologic disturbance related to a vertebrobasilar 'steal syndrome'. In addition to the absence of an adequate intraarterial route for embolization, no venous route was available, since the right vertebral vein was thrombosed at the time of the initial injury. Total occlusion of the fistula hole was, therefore, accomplished by direct puncture of the blind segment of the affected vertebral artery (between the previously placed surgical ligatures) with introduction of Gianturco steel coils at the fistula site. All neurologic symptoms and signs disappeared after the fistula was obliterated.
