Vertebro-vertebral arteriovenous fistula (VV-AVF) is an uncommon vascular disorder characterized by an abnormal direct connection between the extracranial vertebral artery (VA), as well as the first and second branches of subclavian arteries, and the draining veins of the paravertebral venous plexus. Endovascular occlusion or surgical ligation of the high-flow arteriovenous fistula is the main goal of treatment for VV-AVF, but there are no guidelines for the best treatment to date. Endovascular treatment is the primary treatment procedure due to its safety, effectiveness, and simplicity.

Objective: Vertebro-vertebral arteriovenous fistulae (VVFs) are a rare disorder characterized by a direct shunt between the extracranial vertebral artery and the veins of the vertebral venous plexus. This study aims to comprehensively review the characteristics and outcomes of endovascular treatments for VVFs at our center.
Methods: A retrospective review was conducted on 14 patients diagnosed with a VVF who underwent endovascular treatment at Siriraj Hospital from January 2000 to January 2023.

Vertebro-vertebral fistulas (VVFs) are uncommon vascular pathology. It can be either primary (spontaneous) or secondary (iatrogenic or mechanical trauma). Spontaneous vertebral arteriovenous malformation is often associated with connective tissue disorders.

Pediatric pial arteriovenous shunts in the brain and spine are challenging to understand because of low incidence, variable presentation, and associations with genetic syndromes. What is known about their natural history comes from reviews of small series. To better understand the natural history and role for intervention, two cases are presented followed by a review of the literature.

Vertebro-vertebral fistulas (VVFs) are vascular lesions that may develop after trauma or spontaneously in association with connective tissue disorders. We present a rare case of a post-traumatic VVF in a young patient presenting with a painless swelling and a bruit in her left upper neck. Digital subtraction angiography showed an arteriovenous fistula between the left vertebral artery (VA) and the vertebral venous plexus with significant steal phenomenon.
