  • Title: Endovascular stent-graft treatment for a traumatic vertebrovertebral arteriovenous fistula with pseudoaneurysm.
    Author: Li F, Song X, Liu C, Liu B, Zheng Y.
    Journal: Ann Vasc Surg; 2014 Feb; 28(2):489.e11-4. PubMed ID: 24200138.
    Abstract:
    The 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.
