AbstractThe rarely occurring vertebrovertebral arteriovenous fistula (VVAVF) is characterized by abnormal direct communications between the vertebral artery or its branches and the neighboring venous system. We present our experience using a stent graft to occlude a chronic, traumatic VVAVF. A 40-year-old woman with dizziness and loud bruits from the occiput underwent digital subtraction angiography (DSA), which revealed a VVAVF with pseudoaneurysm at the C5-C6 level, with retrograde flow from the right vertebral artery. A stent graft was placed across the fistula after balloon dilation. The fistula and pseudoaneurysm disappeared immediately. After 9 months, the patient remained asymptomatic with a patent stent.Copyright © 2014 Elsevier Inc. All rights reserved.
