Fig 3. Right vertebral arteriovenous fistula after a stab wound injury of the neck. A, Prominent ascending and descending venous drainage with the presence of pseudoaneurysm (arrow) is noted. B, Uncovered stent deployment with coiling (arrowheads) was performed. There is partial occlusion of the pseudoaneurysm and reduction in venous drainage in the immediate postreatment angiographic images. C, Angiographic control image 18 months after treatment shows normal flow through the right vertebral artery without evidence of fistula or pseudoaneurysm. D, Reconstructive endovascular approach by using a stent (double arrows) and coils (arrowhead) was accomplished. E, Transverse T1-weighted MR image demonstrates the right vertebral AVF compressing the cervical spinal cord (arrow). F, MR control image 18 months after treatment shows AVF thrombosis (arrow) and patency of the right vertebral artery (arrowhead).
